Re: [MV] fouling sparkplug and timing question about M151

I think Joe answered all but one question.  "can an engine run 180' out of time?"  Yep it sure will try!!!!  It will sputter, cough and spit.  It will have you grey in no time at all.  Be very diligent when checking the timing on any engine.  Be a perfectionist.  Cause its a pain in the butt to come back and do it again.  Been there on M151's and M35's as well.



As for the rest of the electrics, not being electic savvy, but a gear head of years.  Yes the porcelean may have a hair crack in it, ANY PART in the distributor may have a hair line crack in it, or the electric components inside the dist may be bad and causing weird problems.



Yes the ground, engine to body/frame, is another good place to check.  dont just tug on it, take it off and clean both ends and both attachment points.  Make sure the strap is good as well, not frayed or "worn".



Go back and check the simple things first.  How is the plug fouling anyway?  That is a big indicator of what is wrong...........too hot, too cold, oil, fuel +/- ........look at the symtoms then doctor the remedy!

Just ask any Amateur Radio operator. A cracked insulator will cause a weak spark or no spark at all, on the other side of the argument, NO ground connection, or a poor ground connection will cause such to happen, too. By "ground" I mean return path to the magneto, that being a poor connection between the plug and the head of the cylinder, dirty threads, oil is an INSULATOR. Also, carbon tracking, or other impurities making a resistive path from the center conductor to ground. All of the above could happen to the wires, too. Run the engine in a dark garage and see if you can spot any arcing along the wires, connection, etc. Joe --- "Mil-Veh Co." <milveh@sbcglobal.net> wrote: > I know a spark plug can actually look pretty and > clean > in good shape, but it still won't fire right and we > call it a fouled plug...ok fair enough and let's > skip > the part about dirty electrodes, thats a given they > won't fire right, but what possibly could happen > internally that would make a plug not fire or fire > weakly?
