I have not touch the carb. adjustment screw (didn't do syncing after carb. clean as there was no reason to), do I need to sync. carb. after cleaning? I've checked all the vacuum hose and they were correct, fuel line not clogged. Again, it only dies when there is any throttle manipulation, can't figure out why.... |
I think there may be something assembled incorrectly. Are the "collars" or Needle Jets installed? Because it starts without choke, it sounds like it may be getting too much fuel. Are the diaphragms in good shape and installed correctly? Did you remove the idle mixture screws and check the passages and o-rings? They can break and get lodged. The idle mixture screws should be set to 2.5 turns out as a starting point.

Once running I would sync the carbs and adjust the idle speed.
Fixed! — anh3, Mon May 06, 2019 3:01 pm || |
