Hi, I’ve been running into some carburator/fuel problems. For the last month, my ‘86 Volvo 740 Pierburg 2B5/7, has had a rough idle. Dropped in RPM’s, then stalled. Whenever I was driving in 4th or 5th gear and did a pull, it started stuttering as if it wasn’t getting enough air or fuel (no idea). I thought it was just a fuel issue (bcs I drove on e10 95 fuel for some time and the car had been sitting a few months before I bought it.) Changing the fuel filter, didn’t help. Usually I do everything myself, but I had no idea what the issue was.
Went to my local (classic car) mechanic, he told me that one of the compartiment in the carb wasn’t getting enough fuel, he took apart the carb, changed the gaskets etc. Turns out it didn’t help, issue remains the same.
