Im at my wits end, Every time i get a gas powered anything with a pull cord it a problem. i drove out to commanche land and snagged this old sears briggs powered compressor 3.5 horse horizontal shaft from early 70's-started fine at the guys shop--tiny bit of smoke, Take it home and used it 4-5 times and suddenly it quit-Got more fuel and it seemed to have a problem getting its self priming circut to take fuel, --got it going again then the next time--it acts like it sucked trash up its tube So i took the tank and carb off, cleaned everything out, re welded the tab at the bottom of the tank that bolts to the block, got about a tablespoon of gritty rust dust out of the tank.
The carb--There aint much to one of these. I cleaned it with the carb cleaner-parts tag wire in all its little passages--The diaphram looked good so i reused it
At this point a frikkin go cart motor has kicked my ass and I have thrown up my hands, the only thing I can think could be a problem--The tube that goes down into the tank did not fit perfectly snugg in the hole on the carb and this seems to be a point where the siphoning is loosing its suction---But these were not glued in with sealer, So.....?????????
