Dirt in the circuits !! Suck on the carb !
I called the owner and gave him an update. Turns out he's got the same year Monaco (bizzare right?) That runs well. We're going to swap the new Yorker carb on the Monaco and see if the issue transfers
And im starting to think there's debris in the new carb
I was going to suggest NOT running the Monaco carb on the New Yorker w/o getting a good fuel sample from the New Yorker first,,, as you slip quietly and unknowingly further down the rabbit hole..
It would be wiser to put the new yorker carb on the Monaco. Or pull the carb apart and look inside..
Or the fuel Jason ! Sucking on the carb could dislodge it . Its easier to do than disassemble the carb !
It would be WISEST to fix what he’s got in front of him (2 carbs and 1 vehicle) rather than to lick another door handle! Before you know it, he’ll have 2 old Dodge/Chrysler’s that don’t run right.
Usually if there is junk in the fuel, beside plugging the fuel filter, it will effect the needle and seat and cause flooding more-so than immediately plugging new carb passageways. But who knows? Anything is possible and it doesn’t take a lot of junk in the wrong place to anger a carburetor.
Jason, did you drive the New Yorker after you installed the new carb, or did you just run it in your driveway?
Before I had my car's fuel tank coated inside my carb would get filled with a fine rust powder, so fine the fuel filter didn't catch it. The filter looked clean but the carb would fill with this powder in 15-30 minutes, depending on the speed. A clean tank and new sock filter on the pick up tube cured the problem.
I did an autopsy on the original carb. The bottom of the float bowl had a layer of sediment and you can see the damage from the ethanol fuel. The fuel bowl had a rusty "water line" in it. The old carb was definitely done.
The tank was coated, a new sock and fuel filter was installed and I purged out the lines into a clean water bottle. Now it's a possibility that fine debris got past all that.
I did the old, Rev it up and choke it out trick to no avail.
