I know this has been touched on before but from what I have seen it doesn't match what I have.This is the two that I'm working on.


These are the two I have been working on today.Now I have got them both the start and idle,but revving is another story.I just can't seem to get the springs to pull back hard enough to get any kind of revving going on.
These pictures here of the springs is the best I have it so far,but still not what is should be.



Now I know that's proberly not the right position,but I just can't seem to get it right.I wish I knew more about these engines.I guess by playing around with them I will learn.So how should they be?

Now I take it this butterfly (pictured above)should not be at full throttle position? At all? As while I was playing around with it I pushed it to the full throttle position. omg I thought it was going to eat me up and put me in the catcher.I certainly would appreciate help with this set up as I have nothing to go off.I don't have any manual on these engines so I haven't anything to check with.

if im seeing it right ? the yellow spring goes into the long hole in the top of throttle control . something like this ........ this was a good running machine when it was borrowed as his stopped for reasons unknown !!!!
the triangle shaped bit the small silver sprind is connected too i use to adjust idle speed sometimes bend it back or forward as needed , might help i hope

Hi Blumbly...Good to see I can help a mate out that has helped me..

So, to solve your problem, I would start by putting the spring in the designated place. Looking at the picture below this tab that I have circled, you can bend to the right to increase the rpm's which puts more tension on the governor spring, or bend to the left, to decrease the rpms, which puts less tension on the governor spring. (bend with a flat blade screwdriver or pliers) This is how you adjust the rpm's on this engine. It should hook in here:


So when hooked in properly, it should look something like this:


Be careful not to bend the tab too much, the maximum rpm's for this engine at full throttle is 3200. Set it with a tacho. Remember to have the throttle cable adjusted properly.
Try this first and see how you go. Hope this helps for you.

Sorry vccomm. We must have posted at the same time, lol!!

I wouldn't have posted my post if I had seen yours.

Well at least Blumbly has the right information from two people. lol

hahaha yeh and cheers mate , now its gotta work i hope never be sorry , it all helps

Thanks guys that's where I had the spring to start with but it just didn't make any different's at all. That's why I changed its position and it sort of works. I've tried about 3 different springs all do the same. I just don't know what's wrong with both of them.

So what happens when you put throttle at the run position? It doesn't rev any higher?

I know you had the governor spring in the right place before, but did you try bending the tab to increase the rpm's? Try bending the tab with the air filter off and the engine running at full throttle. It should increase the rpm's.

I think you mean the tab closest to the engine that has the small spring on it . Once you have the machine running at full throtal then move the the tab with the small spring using pointy nose plyers back or forth to adjust the tension on the govenor this inturn will give you less or more revs to which ever you need. Hope this is of some help cheers roebuck.

I fogot to mention when you take the air filter off to ajust any spring setting /I always put the air filter screw back in the carby as this will help keep dirt out of your carby and help tune it properly while its running. If you still have trouble I can always put a picture up to show you what I mean.

Thanks guys that gives me a couple of things to try when I get back to them. As it is now when I go to full revs it does increase its rpm's but not very much. That's with the spring where it is now. When the spring is at its right position there is no change.

Hi blumby,

Move the plyers foward and this will put more tension on the govenor spring and will pull your revs up to the desired rpm. If this dosent do any good maybe check that you have the plastic and rubber ring inserted correctly in your carby before installing back onto the manafold as they can sometimes dislodge upon installing or forget to install one or both which is easy to miss sometimes . Cheers mate hope I'm not annoying you rob.best o luck.

Ok cool another thing to look at. I'm sure something will work with that. One did have bent arms on it so maybe I didn't get them straight enough. I'll let you know how I go. Hopefully will get a chance to have a look some time this week after work. Your certainally not annoying me and I feel it will all help.

Roebuck. That tab that you have the pliers on is not the governor adjustment. That is connected to the anti surge spring. Bending that tab that you have pictured is to stop initial high surging when you start the engine. And sometimes as mentioned by vccomm, it can be used to lower the engine idle.

I would like to make it clear that the way to adjust the engine rpm's is with the tab that the governor spring is connected to. Not the anti surge. If you go back to the picture I posted I have circled it in red. I would try this first Blumbly and put the spring back in its proper place.

I think that the help that everyone is giving great, that's why I enjoy this forum, because people are very generous here, but I just want to make it clear the proper way. Because this is usually a very simple problem to fix.

Thank you.

Thanks James I hope it is simple as I don't want to spend a huge amount of time on these.

Its good to always learn something new . Sorry James I wasn't trying to correct you in any way . I am learning myself and appreciate every bit of imformation I can look at. All the best rob.

Well I just don't know what is going on.No wonder I play around with 2 strokes.Why can't Briggs just design a linkage set up? I have put the springs back to there correct spot and bent the arm a little.The lawnkeeper one is almost doing what it should.I'm just not sure it's idle is slow enough.It does rev but not much more than idle.The Vantage does pick up revs but then it revs to full revs and before I can get to it then shuts itself down.With the black piece connected to the butterfly how far should that move? I'm assuming that it should be around the half way point.As more than that does sound like its starting to rev a little to much.

Hi Blumby, at full throttle the black piece should only be about a quarter of the way off fully closed(so nowhere near half way). There isn't much difference between idle and full throttle on these setups so the lawnkeeper is about as good as its gonna get without going to too much trouble. As for the vantage judging by the symptoms(fully revving out then dying) try a couple of simple checks first; Is the carby sealed on the manifold correctly? Remove the blower housing and check if the manifold is loose or cracked.
Swap the 2 fueltank/carby setups around (as complete units) to see if you get the same symptoms or to at least eliminate the possibility of a dodgy carby diaphragm.

Thanks Bigted I'll give that a go.Well in that case I might have the Lawnkeeper just about there then.I just have to adjust the cable as it's not quite making it to the kill switch.

All good found the problem with the lawnkeeper.It turned out the small spring had broken and somebody had made it shorter.Therefore not returning to idle,if that's what they call idle.
Here it is ready for sale.





Now I'm still learning how to date them does this mean 2008 or 2006? Or do I have it completely wrong?

The problem with the Vantage was I didn't put the carby back onto the manifold correctly so the o-ring and the plastic thingy was just flapping around in the wind.My bad.It is almost ready to be sold as well.I haven't taken any pictures of it yet(ran out of daylight).I will tomorrow and show you how it looks.Any guess on the sale price I should put on the Lawnkeeper?
Just to add I still really don't like working on these.I really think they should have some king of linkage.There really doesn't seem to be much of a rev change from idle to flat out.

Oh Blumby, stop whining, theyre not victa 2 strokes...lol
Youve done a great job on the lawnkeeper, i sold one today for $160. it just depends on the market up there in sunny QLD and how much competition you have in the neighbouring suburbs, but $140-$160 for a serviced machine is not unreasonable.

Great as I think I have already sold it.I did say around the 160 mark for it.Just have to find out tomorrow as to whether they want it.

Good on you blumby, if your into doing them up for onsale its good to do 2&4 strokes and once you've done a few 4 strokes you'll find yourself wanting to do more allthough I think you are addicted to 2 strokees. Their all fun to play with and more options and you get plenty of trusted advice from the outdoor king forum. Cheers roey

I'm not to sure about wanting to do more. Maybe if they had a linkage it would be better and easier. If it wasn't for selling them to make a few dollars then I couldn't see me playing around with them. I do prefer 2 stokes though. Now that I have these 2 done now I have two 2 strokes to do then another two rover 4 strokes. By the time I'm done should have 6 mowers to sell. Also yes there is a good network of knownledgable people on here.

you will find the more you play with 4strokes , the easier they are though . try out new things , adjustments and the like , allhave them just hard to find and sometimes it doesnt feel right to bend tabs to adjust speeds ! now you done 1 the next is more fun good luck with it

Your properly right there vccomm,but I don't share your enthusiasm in doing more.Have managed to to get me both done.I will take some pictures of the vantage and post them up.Even that one came up looking near new.Next I have three Victa 2 strokes.Here,




..and then 2 Rover 4 strokes.Here.


Now somebody was asking about some parts on the this mower.

I can't see me doing anything with it.So could they PM me and let me know what they want off it.
Thanks.

OK here is the Vantage all done and ready to be sold.




Not the best place to take photos but you get the idea.Went to bunnings last weekend and found that they still stock and sell these mowers for $299.So I think if I get around the $150 to $160 I'll be happy with that.
