I have a '78 124 that does not like to start up when it's cold outside, (to me that's 45 to 50). It starts up and then putters out. It takes a light touch on the gas to keep it going without backfiring and quitting. I have rebuilt carb, replaced timing belt, valve shims, tune up, adjusted timing... It runs good after it warms up, it's just when cold. Any ideas on what to check?
