Thanks for letting me join. I have lurked a long time. Great knowledge here. I have myself a mess. I have a 84 near mint 720. Had head gasket replaced and it ran great a couple weeks then it started hesitating in between first and second gears. Just jerky and when in town it just runs rough. Get it on the road its fine, lots of power etc. Runs great. Seems head gasket is good, and put new plugs and wires on and replaced both coils new fuel filters and pump same problem. Only thing that sticks out to me is one coil has a red wire on the negative terminal. Seems red should be on the positive. Also it is using double the fuel it used to. Any ideas? This is my daily driver, I hate to park it. But tired of the money pit it is becoming. Thanks!
