I'm in Everett so can't help U with a shop but every carb Ive ever purchased is Holley and Ive been around them alot for some time. So I would be happy to help you with Q's and I have a couple of in depth books on the them. They are the simplest on the planet IMO. I strongly suggest first that you make sure the ignition system is in perfect working order or you may find yourself beating a dead bush. What is it doing that you think it needs tuning?
