Spark plugs?

Probably correct on that. I'm sure there's a fix for that. Guys race these predator engines in racing carts.

Edit.. disconnect the low oil cutoff switch. Just remember to check oil level.

 

I figured there was a way to deal with. There’s quite an aftermarket for these engines due to all the racing that gets done with them.

My experience is that people seldom actually wear spark plugs out in small engines, in cars/trucks, sure.
More likely that a small engine fouls a plug than wears it out.
And I agree, Champion plugs suck.

 

Update:

Spent $3 on a new NGK plug, and the old girl started right up. It was high time, the plug that was in it when I bought it, wasn't even the correct one.

Good thing, cause I just spent $26 on two new PTO belts.

Can't be sure the coil isn't going bad, because it was hot when it wouldn't start. But after fretting about correct torque, etc., I'm just gonna enjoy my success getting it running again!

 

Glad that worked out for you. Years ago I put an incorrect spark plug into a one cylinder engine in an old garden tractor just to see if it would turn over. The plug exploded in the cylinder immediately and the porcelain shattered all over the place. Not one of my smartest experiments.

I used to change spark plugs after every 1/4 mile... there wasn’t much left of them.... lol

 

That's an extreme situation, you know. Were you running nitromethane?

 

That sounds like a good experiment to share. Hopefully there were no injuries to you or the engine.

I once put a stick into a one cylinder block on a 700 Yamaha Enduro through the spark plug hole, to check something, I don't remember what (travel, maybe). I then turned the engine over, and promptly broke the stick off in the head. Had to disassemble it to get it out.

Generally speaking, curiosity is a great thing. But, we all remember what it did to the cat.

 

Yes... lots of it ... lol
