Roger,
I cleaned the carbs in carb cleaner and blew out all the orfices but as you state one could still be clogged. I figure I may as well order carb rebuilt kits due to thinking the same as you stated in possibly having old seals and dried up O-rings. I will leave the clip where it is at and go through the carbs again. When I did the synching I did it at all RPMs. They seemed to be synched much better at the higher RPM (steady green) and would be 'flickering' at low RPM. I was using a borrowed Cab Mate with the LEDS.

I had read someplace that the plug gap was best at a smaller setting up here in the north country. I am in northern MN and it was in the 20's last night and up to a whooping 40 degrees right now but supposed to get up to 70. :) I will reset them to 0.25 and see if that does anything.

Thank you for the help.
Keith

Hi Keith,

Your right about the gap in cold country. If you live in MN then I would use .023 for the gap. I have seen many a carb that has sat a long time and the jets needed to be rodded out because carb cleaner won't touch the dried on fuel residue.
