View attachment 1715331811 listen very closely this time. He has not paid for this carburetor whatsoever. It is not working well for him seemingly no matter what he's doing. He was going to pay x amount for this carburetor. If he took x amount plus $100 he could probably buy a brand new carburetor. You also suggested he started drilling holes in it which he is already said would just make the problem probably worse. He can get out now and have no problem whatsoever.

Ok. I said spend 8 dollars on two butterflies and drill them out. I realize it's not his carb yet. It's still just 8 bucks and some drill bits.

If I was home I'd send him two for free. But I ain't driving 3.5 hours one way for that. Maybe someone else here has some (I probably have 20 or so of them) and they can hook him up.

You math doesn't work. If he is going to spend any more money that what this carb is going to cost, plus two butterflies, he's better off buying something with removable brass. Used that's about 400-450 bucks.
