I have just refitted the 1500 engine in my track X after a year and a half doing body repairs. The engine hasn't been touched in that time, I had the headers ceramic coated before refitting, and on start up the pipes from cylinders 3 & 4 are running hotter than 1& 2, so much so that the white ceramic coating on 3 & 4 has turned a noticeabley darker colour than 1 & 2. I am thinking 3 & 4 may be running a bit lean, but I have checked everything I can think of that may be causing this, float levels, all jets in both carbs, progression holes, fuel passages as much as possible without stripping completely. Can't find anything wrong. Car is not registered, so only running between 1200 and 5,000 rpm in the shed, no load. Any suggestions would be appreciated.
