hi all...i did away with my points and put on a solid state coil.the engine is a briggs cast iron 16hp model 326437.any way ive got good spark and gas but it just wont start. any ideas? i can shoot it with ether but still no start. it has to do with timing of spark i know . how do i get it timed right? the only thing i can think of is to move the coil bracket. i have it to the far left for gas where it was.
