been watching all your vids, cause Im trying to build a big homemade rc car with a 31cc engine. Having problems with the ignition system right now (its shorting out i think the flywheel with the magnets is hitting the magneto). I was wondering - is it safe/does it damage the clutch if I were to put sideways strain on it, like putting a sprocket and chain on it to drive my wheels?

Well, usually it is fine as long as the sprocket on the clutch shaft is centered propperly. But I'm guessing the 31cc engine you have is a half-crank homelite/ryobi. The clutches on these engines wil not handle the sideways strain (i've tried this before and it ruined the clutch). You will need to have a support bearing like I have used.

@fingalickenchicken yea its a ryobi 410r and thats what I thaught, thanks for the advice! It came as a cultivator, so there is a work gear that attaches to the clutsh, and then to a heavy duty strong axle i plan to directly drive wheels from. This way it will also act as a break when I decreas the throttle. Dont suppose you know how could modify a normal ball beaing mini bycycle wheel so that there is a fixed 15mm axle going through it to drive it? Thanks again.

No worries.

For the wheel, you will need to make a flange that pins onto the driveshaft, then bolt/lock the flange on to the wheel somehow. The easiest way to make a flange without a lathe is to buy a aluminium pulley with a 15mm bore and drill 2 holes through it. If the wheel has spokes, you can lock the flange onto the wheel by threading lots of wire through the spokes and the holes in the flange. If the wheel is solid plastic/steel, you may need to drill some holes in it.
