I sent Drew a pretty detailed email—he replied. I was hoping for a limited rebuild on the center carb, but he prefers to do all three or none. I understand that; I’m self-employed in a service field too, and sometimes selective jobs aren’t worth the time or hassle.
I’m sure he could restore the carbs to factory spec, but like others have said in this thread, the real issue seems to be heat—fuel is boiling over, and a factory rebuild won’t solve that.
I’m now less than 75% convinced my warped main body was the culprit. I carefully filed a couple of high spots—took off very little material—and it sealed fine, so I'm confident to move forward.
I just ordered about $250 in parts, including phenolic spacers. Nothing off-the-shelf fits exactly, so I’ll Dremel them to match. Found enough small issues I
can fix to justify seeing this through before jumping to an extremely pricey tri-power EFI system.
One of the missing parts was the center carb’s fuel bowl vent baffle. Installing that might help a bit.
