Will only start with choke on - if I let it run with choke on the exhaust pipe glows red. I can take the choke off if i keep reving it and the pipe quits glowing. It will not keep running with choke off. I replaced the diaphram and the two o-rings also the needle valve had a bad o-ring I replaced it too. I'm at a loss. I cleaned the carb very good. Help!!

Your pilot circuit is not working right.You got an air leak somewhere in the carb. In my case it was the after market fuel/air screw. The o-ring wasn't seeding properly. Check your hot start and choke to make sure they are fully closed in the off position. Make sure your fuel/air screw is working properly. Check the boot on the front off the carb for a leak. Start the bike and spray starter fluid around the carb. If it rev's up, replace the boot. Hope that help. These are tricky to trouble shoot and get right. Good luck.
