Pulling this carb apart is getting old. I have tested auto choke and it is working as described in test procedure. After driving buggy all day for hours, I let sit overnight and she just dont want start back up the next day!? It runs pretty decent and will idle after driven a bit. I crank it over plenty and after will check plug and is bone dry. I have removed vacuum pet cock and installed a gate valve so it has plenty of fuel to carb. If I give it a shot to the cylinder it will start and then run fine!!! What gives???
