Carbs and idle
Posted: Sat May 14, 2005 4:36 pm
Update on 4378 and the idle/carb problem:
I changed out the carbs (I had a spare set - the new SU ones) and problem solved. Idles smoothly down to 500 RPM; set it at 700 after tuning.
I think there is an air leak either at the butterfly valve or the shafts. Haven't studied it enough to know yet though. Will figure it out when I rebuild these.
Thanks to everyone for their suggestions.
