Engine would fire over if you spray carb cleaner in the manifold, and then die... Got a carb kit installed after a good cleaning. Same thing.......... Took carb apart again to double check orifices, all clean......... I noticed 2 recesses that are empty, l started thinking maybe someone had removed the welch plugs and not replaced them...... The kit came with 1 welch plug. Kit number 792006.
I just spoke with the owner (it's on a MTD tiller) and he says no one has ever worked on it, it is the original carb......
Thanks.......... I'd checked the passage going across the nut, had failed to check the one going down from the top......... That's what happens when you get in too big a hurry and try to rush things............
