After I messed up my timing and then reset it, the car is very sluggish going into the next gear. I know bad timing messes up a carb but why this? I reset it back and after finding a bit of a leak at one head gasket and fixing that, it sounds better than ever. I didn't change anything on the carb except a bit if fiddling with the needle valve (mix ratios) and I put that back to where it needed to be. I'd rather not pull the carb and take it apart. Just don't know why it's sluggish all of a sudden.
