I bought a model M back in sept. runs like a damn aslong as you have the choke on and a piece of tape covering 90% of the air hole. I painted it made it all nice and shiny looks great. Now i cant even get it to fire. I have tons of gas if i really want to i can make gas poor out the exhaust pipe.. ive made the gap bigger on the plug it makes a nice whiteish/blue spark. Has great compression after turning it over for ten min your arms are ready to fall off.. I even hooked a 1.5hp electric motor let it turn for 20min not a whisp of smoke once in a while it will make a whisp of white fog when you give it alot of gas and thats it.... Any ideas???? I guess i should have left it rusty and trusty now its shiny and whiny
