Was just out on a test drive when it suddenly started surging and shut off. When I tried to start it again it was only running on 3.
What I checked:
- Timing was the first thing, flywheel and cam marks lined up. I was worried I skipped a tooth. Stuck an endoscope in each cylinder, nothing colliding.
- Compression test, each cylinder was exactly at 154.
- Cleaned distributor points and checked cables, all good.
- Spark plugs appear to be fine. It is showing to be running a little rich, but that's another issue I was working on, hence the test drive.
- Builds oil pressure as normal.
- I'm fairly certain there's fuel in it, I put in 4 gallons last week and haven't been running it enough to burn through that yet.
I was going to run a spark test and figured I'd just see what it did with the DME reinstalled. It now fires up fine, all 4 cylinders, but then shuts off. Actually very consistently; starts, idles for 1 second, shuts off. When I try to give it a little throttle to prevent it shutting off I now get a belt squeel, which was not there before. I'll take the accessory belt off to rule that out, but I don't think that would be it seeing as it's never sqeeled before just now. Also power steering isn't hooked up so it can't be that belt.
So...any thoughts before I start tearing things apart?
