I bought a rebuilt kit and followed a lot of the instructions found on TT especially using http://www.thumpertalk.com/forum/showthread.php?t=688056&highlight=re+jet+stock+carb to show how to disassemble. I replaced the needle valve and set with the one in the kit as well as the pilot screw and bowl gasket. NOW THE DARN THING WON'T START! I can get it to fire with a little ether but that is not the best - I know. Where do I start?
