Hey datsunman, I had a similiar problem a couple of weeks ago. ddgonzal really helped me out. Go to page 3 of the main forum(bottom of screen) and it's under the topic called "stupid question" He gave me a very detailed explanation on how to adjust the carb. As for the timing mark, I'll go out and look at mine. Is your engine an A-12?

I finally figured out the sign in and I have a tune up question or two for a 1971 model 1200 Coupe. #1 The pulley has 5 slots on it and a single hash mark on the chain cover. Which mark is the TDC on the pulley? It seems to be the last one in the direction of rotation, but I am not completely sure. #2 I use the old Haynes manual for carburetion initial set up. I put on a new manual choke carb. The low speed idle screw is initially turned out 2 turns from being seated. The car doesn't seem to idle good unless it is out 3 or more turns and was wondering what the general seeting may be for other 1200 owners? My previous carb was about 1 1/2 turns out. I certainly would appreciate a reply and under the old board I was "Datsunboy1200", but a computer crash has kept me off since ya'll changed over. Thanks again, JJ
