Should there be a lot of unburned fuel dripping out of the exhaust. The motor is a 32 os max. Iam running 30% heli fuel.

Thanks

Yes. Oil coming out of a 2 stroke engine means you are getting plenty of lubrication. If you lose oil and smoke, then you are running WAY too lean.

How much is a lot..? Pouring out as a steam or dripping slow drops

Pouring out... No... Till you are running stupid rich.. Like during break in or something or after engine flooding


My helis drip a a few drops right after flight and then a very slow drip., point is ... Yes like tony say, you should have some always but too much is an indication of a very rich motor , and basically wasting fuel

No it isn't poring out. But it blows out a fair amount when it is setting in a idle position. I will try to take a video tomorrow so it is more clear. I don't think it is a issue. I have only had a nitro for about a month or so and just gettin good weather to run it.
