Oil leaking from exhuast

[George Tirebiter]

Just breaking in 66cc chinadoll, after every run a small amount of oil is leaking from the exhaust pipe. Is this normal?

yes - it'll clear up later

Depends on where it's leaking from. Dripping from the outlet of the muffler? That's normal. But if the leak is at the cylinder where the exhaust attaches you have a problem. The kit exhaust gaskets aren't the best and the flange is usually warped and needs to be ground flat so you have a good gasket surface.

What fuel to oil ratio are you using? If you're going by the kit instructions that tell you to mix @ 16:1 you need to slack off on the oil a little. 24 or even 32:1 is recommended here.

It leaks from the outlet of the muffler. Just a few drops at a time. I'm using
24:1 and I just ran through my first tank. Thanks,

Hey George, the kind of drip you describe is completely normal and nothing to worry about. You will want to remove the muffler and clean it out well with a solvent or degreaser and, ideally blast it out with compressed air after but you should wait until you've broken in the engine a bit more until you do or you'll just have to do it again. That is unless it's getting so plugged up that it is resisting a proper exhaust flow and fouling your plug up. Keeping in mind that plugs will tend to foul a bit during break in with the heavier oil/gas ratio.

OK, thanks for the info and the humor. LOL!
