A mate dropped off his Deutscher H660 here a couple of weeks ago and asked me if I could sell it for him because he sold the place he had up the bush and it is way too big for any of the lawns he mows.
I have just had a look at it and it is impossible to pull start, and on reading up on a few reviews that is what they are all saying about this Briggs motor, very hard to pull start and if you are not careful they will kick back violently which I have discovered. I have a 10.5 flathead motor here with electric start, does anybody know if this starter will fit on the Intek OHV motor. All I can think of is fitting E/S on it. I can drill start it sometimes and the motor runs fine but even with the drill it can still kick back. Does anybody have an idea on fitting an external decomp valve to stop the kickback. Obviously these Briggs were a dud motor from the start from the reviews

Hi Norm, before you try the ES on it just make sure the valve clearances are right on it. They can be a real pita to start if the clearances are out resulting in your symptoms.

Hi BT,
Thanks for that I will have a look at them, these motors are just too big to be pull starting them. Just pure stupidity from Briggs

Even if you're a bodybuilder, you're likely to just break the starter.


Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!

I think I will tell my mate to see if he can flog it off as a non starter, I just don't have the interest to bother messing with it, these big pull start Briggs are junk

There's always the drill start.

Hi MF,
No way am I drill starting it again, got it started twice but the kickback on the third try nearly smashed the drill and it ripped the drill out of my hands, so I won't be trying that again

An impulse starter would have been good for that.

All the fools at Briggs should have done is fit electric start on these bigger motors, aint rocket science and they have been fitting electric starts to mowers for many years now .

Hi Norm ,BT and Mf,



I would disconnect the spark plug wire and pull the motor over and if there isn't any kickback with the spark
wire off then I would replace the spark plug as I've had a few that an old plug would advance fire.

As BT mentioned valve clearances must be checked ,also I have heard of a few problems with these motors when old like
worn timing gears that can move a tooth.

As you say Norm as it's not your mower it's not worth getting too involved but may be worth checking the quick easy things.

Cheers
Max.

If it's the Briggs & Stratton 6.5 INTEK EDGE Model Series 121600 it's OHV Norm.

Hi Max, the identification plate on the cowl is missing, but I believe it is a 10.5 Intek, 6.5 is easy to pull over and they were fitted to the 22 inch machines. Yes this is OHV but is it pushrod or OHC

Hi Norm.

Yes it's pushrod , I'm surprised your 10.5 doesn't have electric start.

Another check would be to check for bent pushrods.

Cheers
Max.

Thanks BT and Max,
I picked up an H26 for a bloke 6 months ago and that had a 10.5hp flathead motor on it. I got it started once and just said to the bloke, good luck starting it. I do have the parts here to convert that one to electric start but he didn't want to pay the money for me to do it. Just waiting to see if he comes back this season wanting me to convert it. They are pigs to start

Just as an update on this topic, I have fitted electric start to both these motors and the starters couldn't turn them over. I fitted Victa decomp valves to both of them and they spin over easily and start straight up

I think mine just must be perfectly tuned in - as I find it as easy to start as my Honda GXV160, perhaps even easier. I concede I've read they're infamous for kickback but have had none of it at all on mine and I'm a very normal sized 50yr old. Must just be lucky.

Hi Nick
The issue is well known to Briggs, the cam valve lifter fails and then you can't turn them over because you are hitting full compression too early. They have been known to fail after only 20 hours use and the Briggs fix it to replace it with a new cam that could fail again in another 20 hours. Good for the dealers but Briggs don't care about the customer, they can pay the bill
