ok well here is my latest dillema. i took the engine that was all built up but was not getting spark and put it in my other sled that was getting spark and everything. the stator was dead on the built engine so i took the stator, fly wheel, and the points of the running engine and put on the built one. (built engine has a 440 racing base, same ad my sno pro base that was running, so all is the same) so after i get everything switched boom runs great for aobut 20 mins then no spark again. so wha tim wondering is when i test the stator with a test light i stick it in the stator plug (white one) and 2 of the 4 holes make it light up, and when i test the coild and cdi nothing at all. should all four holes on the white plug make it light up, if not does this mean it was a fluke and CDI jsut went.. please respond really bothering me.. o yah if anyone wants to know the built engine is a 440 sno pro base, chrome molly crank all polished, chrome molly rods polished, shaved heads, ported and plished carbs, and exhaust ports. running HUGE jets love the speed.
