workman75 Posted May 13, 2008 Share Posted May 13, 2008 I know they were fixed screws with that pesky cap....the previous owner has done everything but destroyed these carbs and I've finally got them back into service. While I usually tune by ear and a carbtune, these little buggers do not want to sync or even out. The engine is a fresh top end rebuild, new seals and valves reground. A mac exhaust with dunstall type reverse cone exhaust. I think the jets might need to go up a size...any suggestions? Link to comment Share on other sites More sharing options...
