I got a victa off a junk pile it's the power torque motor first thing I've seen it's missing the decompressor (I think that's what it's called) so to get it running without that I can put a spark plug in right? But where would the hose go too? Do I block it? I'm just doing it to know it starts I will get a new one when I know this.

Just block the hose and put a spark plug in there.

Ok cheers

Ok got it running with another decompressor( dunno how people pull start with a spark plug there) but when I pull start its really hard and almost kicks back like a motor bike why would this be?

Ok my fault I had the blade plate off! I'll try it tomorrow and see if it's any better

Ok got it going need a catcher! But it only starts in max throttle. Maybe I don't have it on choke propperly or is this common on a power torque? My old one did it too

maybe the kill switch leads need attention. on full throttle a little tab on the cam inside the carb just touches the centre terminal and pushes it away from the crosswire slightly. Maybe try pulling the leads out, separating them and try to start.
cheers

Well I doubt it could be that cos it'll run after started, in the choke position. I'll try it again starting with the choke on

A quick test just to rule out the kill wire is to push it down to full throttle while not running (a good shove, hard and fast) then gently pull it back to choke and start, if that does it, then look into the wires.

However, to me like a tuning issue, you can adjust the throttle positioning by lostening the little screw at the top of the air hose.

When done corectly, the trottle lever should stop about one matchstick short of the top of the slot.

Apart from that, thorougly clean the jets and fuel side of the carby, and check the priber buld for damage.

Have you done a work over on the carby, I usually find it pays to sit down for 20 minutes with the carby, a toothbrush and some old fuel, and clean it all up nice.

Where is this air hose screw? Up near the throttle? Or on the carb? I can't see anything on the carb

I assume by air hose screw he means the adjustment screw for the throttle cable thats on the air hose/throttle housing.


You could pop the back off the carb and flip the top of the diaphragm aside and check that when you move the cable that the grey thing inside the carb gets its full range of movement.


Some wont start on the choke, ive had a few like that.

Id assume that a plastic carb as it came from Victa is pretty well sorted. Anything that doesnt work right has had work shop improvements. Theres no way you could get half the replacemnt parts, theres heap of different spring combos.

I'll try that then first I don't really want to pull the carby apart cos it might not run at all after that! Victa should have used holleys haha

No need to be afraid of the carb.

Its a pretty simple thing. Dont loose any parts and put it back together the way it came apart.


Clean a bit of bench space and lay it all out as you pull it apart.

Theres a good video on youtube that shows you how to unclip the throttle cable. Wont be hard to find if you search for it.

The screw I reffered to is indeed the adjustment screw on the air filter housing.

As Bob said, don't be afraid of the carby, the G4/Lm carbies were designed to be fairly simple, most of the components just snap together, the only tricky part is the cut out wires, and there are numeous guides (including a few here) on doing those.

Remember to get the 3 arms of the lifter (the only 3 armed thing in there) into the 3 slots inside the body.

Make sure the diagphram is good, and the right way up (flat side away from engine) and clean out the float chamber (behind the brass screw)

And make sure that the 3 arms of the 3 armed thingy (yeah awseome technical term there Bob) slide in and out freely in the slots in the body. If the dont sand paper or file them till they are a nice slidey fit.

If the springs have to push against any rubbing friction the carb wont owrk propperly. Ive had quite a few ive pulled apart where the 3 leg thingy has been binding up.

Yep, same goes for the "wobbly" trach on top of the cam (the big, grey round thing) that has to be smooth too.
