Onan 6.5NH-RV Running Rough
I posted this in the smokstak forums, but it can't hurt to ask the experts here, too.
1984 vintage Onan 6.5NH-RV. Came with the RV. It had sat for about 6 years when I got it. I changed the plugs and ran some sea foam through it and it's been fine for about 3 years.
Back in June while boondocking at the Pocono Raceway I needed to rely on it when my fridge stopped working on propane. It ran fine for around 10-12 hours when it began doing this:

Runs rough, comes close to stalling (sometimes does stall), backfires through the exhaust occasionally.
It smells rich but there's no black smoke. Choke is pulling off just fine. I took the carb off and cleaned a piece of junk that was stuck in the needle seat. I was SURE that was the problem. Put it back together this morning and it does the same thing.
New points and condenser are on the way, but it seems like fuel?
Ideas?
