Anyone recommend a good mechanic in Sacramento

Timing and Carb adjustment will fix that. Buy a timing light and use the service book for the proper settings. It may take you a couple of times but its easy and will save you money. Shops can charge $100 just to do it for you. Do it once and it pays for itself. If you need guidance the forum is here to help you. The service books can be found here as well. There are links to them to read online. If you were in socal I could show you how. I collect the large Shop manuals that cover most American and some foreign such as VW. From 1954 thru 1982. All the tune up specs are there. Pm me if you need the tune up settings
