i gave up on rebuilding my TR for now and bought a new one. i have completed the break-in process and have benn running the car around a parking lot, but it seems to want to run lean. O.S. suggests starting with the needle valve 2 full turns out from closed. i actually ran it richer during break-in. but as far as driving the car,it will only spool up when the needle is 1 1/4 to 1/12 turns out. does that seem to lean? i have a infrared temp gun(very high quality SNAP-ON gun) and i have been watching the temp closely,trying not to go over 240(210 during break-in). how hot is too hot?
