OK, I think I'm on the right path here to fix my cold start problems. I tried to adjust the start of delivery with the drip method but I could not find a spot where I would get 1 droplet per second. I put everything back together and now it ran like crap. I probably moved the IP to far away from the engine (retarded it). Next I moved it all the way towards the engine and WOW: the next morning it started at 27F without the block heater. Before it sometimes wouldn't start below 30F even when it was plugged in. It still needs two or three minutes of "playing with the gas pedal" before it stays running by itself, though, and that's the question: If I pull the IP out and "jump" one tooth and then advance it even more, what could possibly happen? Would this solve the problem or create new ones? Any other ideas?
