Everyone,
I'm the one trying to figure out why my newly acquired 1971 MGB died on its way to its new home. Was running on a couple of cylinders like it was being drowned. One possibility is the choke on front carb might have been stuck because it drove great for several miles before it puttered and died. Got it started again and home. I have been trying some of the suggestions (those that I can while waiting for routine maintenance parts). Being a newbie with only a Haynes manual so far (more on the way), I am trying to understand how the choke works on these HS4 carbs. From what I can gather the choke actually lifts the jet assembly. Is that right? How is it related to the fast idle screw? I also noticed while digging around that only the rear carb had a choke return spring attached, there wasn't one on the front carb that supplies the cylinders I thought were being drowned. In addition, the throttle spring on this same carb isn't looking so hot either. Since I putz with the carb (moving the piston up and down and getting a better idea of the design), the engine seems to be running on all fours (went around the block). I wanted to take it down to the station tonight and fill it with new gas but the weather is bad here (not like FL though). Just to see if I could get stranded somewhere. It still seems very rich (gasy smelling) but it may be because I have exhaust manifold or manifold seal problems too. So how do the chokes work on these Bs? /ubbthreads/images/graemlins/crazyeyes.gif
