Default Re: help with grubee skyhawk gt5

Runs for a few minutes and quits.....when it quits, do you have spark at the plug? Could be a crankshaft seal (1 or both). The carburetor to the intake hook up (O ring), or the intake manifold to cylinder gasket. To test for a leak if you can't find it either pull a vacuum (best) or put pressure in the case... about 5#. Block off intake and exhaust and use the plug hole. Piston at BDC. How are you set up for tools, if any?

If you have a CNS carburetor, get rid of it and get a NT, so much easier to work on.
