Just wanted to post about a stall out problem I’d been having on a 73 Monaco 400 v8 2bbl (rebuilt from Autoline). Car would start fine and run for about 5 minutes, but as soon as it was warmed up, it would stall out.
I swapped out the carb with a $50 eBay replacement carb today, and amazingly it fixed the problem. Got rid of flat spot under acceleration also, and it idles great now. I suspect either there is dirt in the old Autoline carb or, as one member has suggested, the air horn is warped and was not drawing adequate vacuum to pull fuel through the venturi’s. I will likely take it apart and see if anything obvious is visible. I’ll post pics, if anything interesting.
