I do have a new OVP in there (new plugs also) but where is the cold start valve located? I'll test it. I haven't had a problem since I did the above and it has started on the first crank every day until today this afternoon, when it was actually warmer out. I did get it to start after several attempts at it trying to catch. Almost seems like it's not getting enough voltage but feels nice and strong when it cranks. Sounds like it's flooding and barely tries to catch when trying to start and having difficulty. BTW...my daughter has an 88 300E and it blows my engine away in idle, take off power, and high end power. Runs like a champ!
