Need help!
My Villiers XIIC 148cc long stroke engine has been running briefly and then it has no stroke. I have already done all sorts of things; replaced gaskets, new spark plug, reset timing, had cylinder loose, disassembled carb etc.
What is striking is that even after many start requests, the spark plug is not wet. Carb is a 1 1/8" Villiers with needle adjustment, needle 4.5 and nozzle 2, so should get quite a bit of petrol.
But what am I overlooking? Is it sucking in false air through the bronze bushings on the crankshaft?
Any tips welcome as I don't know any more.
