Need recommendation for a Carb for better MPG!

Get a timing light with digital advance (for accuracy) is my recommendation. The cheaper dial advance lights can be off by a long ways and ones with no advance don't work to check total advance unless your balancer is marked or has a timing tape. Then there's the issue of the mark being hidden behind a bracket and hard to read. @halifaxhops has lights for sale. Send him a pm.
I will do that, THANK YOU!
