BC.....is there some kind of regulator to the vane pump or is it where it makes what ever it make at a given rpm to advance the timing.
I keep reverting to gas thoughts on this,with the popping and snapping at about 1900 RPMs,on a gas motor I'd have said its high or low timing. Withe the doggy idle id say that the timings low. The smoke is the only thing that makes me wonder hard about the pressures being produced by that pump. If the pressure isn't there to atomize the fuel and it dribbles out then it'll puddle in the pistons......right? Causin it to act "flooded" untill I clear it out,hence the super mushroom clouds it now produces.
I'm pondering tearing into it,just to peek inside to see how it works. Hell I've been inside for the spring and that wasn't to bad of a chore. Reckon there's something inside that'll get me in trouble?
