Overheating Engine

Just wondering what could be the reason for the engine to overheat and how to cool it off. I have CH80 Engine if that means anything. I know it was overheating as I can only idle and rev the engine when it's really hot. That and I could feel the heat through my pants. It acts up when it's to hot. It would putter like it does when say your going to slow and it's about to stall due to a very slow speed. Another way to describe it is the sound it makes when you forget the to switch the gas valve to the one position and it's starving for gas..

I hope I made this clear enough.

An air leak will make it run poorly AND get really hot, next step- oblivion.

Air leaks cause lean conditions which kills the 2 strokes. Same goes for incorrect carb settings. If in doubt, run rich.

There are guides on this site (or links) to read your fuel/air mix from your spark plug colour.

Yes, you are running lean to cause overheating, vacuum leak at manifold or at carb. Or the carb need's to be looked at.

I suspect your plug is white? Here is a chart of plug's

Carb does not appear to have any leaks and I retightened it to make sure. The spark plug I have no means to take off. I can't find the tool that came with the engine kit. Where can I get one in Ontario ?

Any auto store, canadian tire etc. home depot/ rona (in the lawn mower section). There are generally 3 sizes, you want the 3/4 inch one (if yours is a Z4C plug), I'd say look at the lawn mower sections first.

Just make sure you can exchange it if you need a different size.

I would definitely have a look at the plug, it will tell you a lot.

The little metal piece that creates the gap is grey and the rest of spark plug is brownish black.

That's a little lean...look for an air leak, or adjust you needle clip down one notch and check it again.

How do I check for an air leak ?
