Carb

[Powerstroke816]

I have a sky hawk and the carb spits gas back into the filter and I was wondering if there is something I could do to fix it or do I have to get a new one?

It's the nature of the beast. All 2 stroke engines will produce some 'spit back' into the carburetor and the air filter. Unlike a 4 stroke with valves that isolate the intake from the exhaust, a 2 stroke will allow some crankcase pressuer, containing the fuel/oil charge to be drawn back into the carb.
There's nothing you can do to prevent it, just keep your air filter clean.

You need to adjust to the float , it's set to high. The carb. is still good

Thanks we already adjusted the float when I got it. It was bad in my old motor but the new one just started a few days ago but not as bad.

The only cure for this is to modify the engine to accept a reed block, which requires other mods as well. Best thing to do is clean the filter regularly.

CNS? I highly recommend you replace it with an NT Speed; very cheap, much simpler, more reliable, responsive, and less of a headache on a Skyhawk.

A slightly oiled air filter catches particles more easily though doesn't it?

Fo'Sho'! Just squeeze it out once in awhile, it's normal as 2Door said.

Do you have the red plastic air filter or the cone style?
