billyt Posted February 8, 2007 Report Share Posted February 8, 2007 (edited) Mark You stated: "A slight pink when you chop the throttle does not bother me as you are cutting fuel off a that point. But only slight. Once again a tradeoff!" That alone tell me that the pilot is too lean, why. When the throttle is backed off, the engine is still turning at higher than idle requiring fuel. If the slide and needle is almost down or down, the only place it gets fuel from at that point is the idle and pilot circut passbye. The pilot is only designed to supply enough fuel for an engine running at low rpms. When one chops off the throttle at say 3/4 throttle the piston is still going up and down the plug is still firing. BUT it is sucking and starving for gas and gets from guess where THE PILOT circut. Ishy is eluding to a similiar thing in the other Sherco post about the pilot circut. My tuppence....

copemech Posted February 9, 2007 Report Share Posted February 9, 2007 (edited) Billy, I do not disagree wit much you ave stated, yet I can tell you that running closer to stoich, on the left side, smoothes the response. The VX plug provides better ignition with no starting problems! That is another story. The throttle chop pink, is as stated, yet to the absolute minimum! And there you find the sweet spot! Never heard any once warm! A very fine line though, and varies with the weather. So there you go!
