Wires cap and rotor are fine, the plugs are new.
the starter seems fine, the ignition module died a while back and it would just crank and crank and crank but not spark, so my feeling is that the starters in these are pretty damn sturdy.
There is kind of a fluttering sound when I accelerate, hard to tell whether its just something shaking around, or the sound of power escaping or something or that sort.
My feeling is that the spark is definitely getting to the cylinder, but there is an intake valve sticking or something like that going on.
I am planning on doing a head gasket job/ minor rebuild with new valve stem seals, pistons rings, headgasket, valve cover seal, and whatever other gaskets come with the kit (intake/exhaust, thermostat, etc.), however the one website I found that carries parts for m115 engines (autohausAZ.com) has them out of stock and back ordered.
That being said, anyone know where I can get m115 engine parts?
Any other ideas as to whats causing the misfire? Is my stuck valve theory a plausible one?
