Just guessing. But if this is a two cylinder. Have you checked the other spark plug.Never shut one down under load. Unless you like spending money.

Do the simple things first. Check fuel flow is the pump working, do you have good flow. Change the fuel filter. If you know enough like suggested above check the choke. Also see if you can manually increase the RPM(just for a moment) could be stuck throttle. This is all low cost or free. Does it continue to smoke blue or just for a couple at startup. Does the exhaust look black, sign of stuck choke. Is the air filter plugged or dirty, clean or replace.

I'm going to check the choke tomorrow, and if it is ok, I'll take it some place to take the boot off the spark plug, I don't want to pull any harder then I have been doing and make things worse. Something that does puzzle me though, before this blunder, I had the hardest time getting it to start, sometimes I would have to walk away for a while, and then try again then usually it would start, but now it starts in about 2 or 3 seconds on the first try, never did it like that in the 14 years I have had it. PS it smells really rich when it's running now too.

Good news!!! It was the choke. Thanks everyone for all your help. RELIEVED!!!!!!!
