I recently purchased a 1985 ramcharger 4x4 318 2bbl. The 318 lacks power thats for sure. Its starts great even at -4 degrees. When driving it has a slight hesitation when you touch the throttle. I decided to check the timing and found it to be a 8. I raised it to 12 (factory spec) with the expectation of going more but any more and the engine seemed to labor. Test drive at 12 and it seemed to stumble under load even light acceleration. I'm thinking lean miss? I did notice that when i reved it to 3600 i only had 25 total timing. Are these factory engines and carbs that lean or do i have an issue somewhere else?
