"I restarted it with a lot of throttle"- - - - - -to paraphrase, "I held the throttle wide open and cranked until it started". Is that correct? If so the engine is flooding. Find out why, and fix it.
Have you done the volume/pressure/vacuum test on the fuel pump yet? Didn't think so.

I have to hold open the throttle, but not WOT and it starts right up. I believe it flooding too and I have been trying to figure out why. I have checked the float and adjusted it twice. Lowered it below spec by 2/32". Needle and seat are clear.
You're NOT reading my responses then cause I have done the volume and pressure tests. I will do the vacuum tomorrow when I have daylight. Geez. Take a breath already.
