This coach had been fully rebuilt and then parked for seven years when i got it.
This made it hard to troubleshoot. It would run OK and then bog down. So of course we looked at fuel lines, filters, old gas etc.
Got all that sorted still no change. Chased vac leaks etc. No change.
Then someone suggested a cracked intake- that fit the symptoms perfectly. The issue would get worse as the engine warmed up but also, the severity would get worse over time. So it made perfect sense that a crack would open more as the engine wormed and get bigger over time.
I scored a good intake and commenced to changing it. And when it was all back together there is NO CHANGEit still does not run right.
So maybe the carb? The Revcon is sitting there, has not been run in over a year. The original Toronado Carb has NEVER been rebuilt, but i swap it out and the GMC runs PERFECTLY!
Ok, that was a long and winding road. Whatever is going on is happening in the carb ONLY.
Here's the symptoms-(before i swapped the carb) engine starts pretty easily, takes off smoothly and accelerates into second gear and then has no more power. If I give it more gas is bogs down like it's gonna stall.
This gets worse the longer i drive it (lately not more than a couple miles)
This carb was freshly rebuilt for the Coop in 2013. it went 1000 miles and did not move again so I'm not inclined to tear in all apart, it's not like parts are worn or thousands of gallons of fuel have run through it.

It's gonna take a lot of Adderall to get this thing right.
