Did a search, didn't find my problem, and hoping the solution helps someone. My issue with a newly received MEP 803a was that the fuel pump would run for about 2-4 seconds and shut off with a no fuel light. There was plenty of fuel and the gauge showed greater than half a tank as well. I...

Update: Put it all back together and set the cold operation slide off. Shutters opened this time exactly as I expected at the temperatures I measured (> 120 degrees). They did not before, and I think this was the real cause. I think only time will tell now, I need a real outage, or for the...

The unit was definitely hot, maybe even hott :). No smoke off valve cover, but it was "I wouldn't touch the sucker" hot. Didn't think to pull my sensor at that time, plus it was wrapped in the ASK. which I have off now for diagnostics. It's definitely not the oil pressure cutoff, not only do...

Ok, I think my post is getting moderated for pasting a link to a manual in here. Removing link. Massachusetts No mouse nests (took off all covers) Ran overnight for 12 hours at 30 degrees, then next day ambient at 40-50 and higher load (approx 50%) it would shut down every 3-4 hours. 20...

No mouse nests. Massachusetts (sorry I'll update my profile). It ran for 12 hours over night at just under 30 degrees F, then when it warmed up the next day (40-50 degrees), it would cut out. Let it cool for 20 minutes, it'd run for another 3-4 hours or more depending on how hard we ran it...

I'm getting overheating on mine only under load, cutout switch shuts it off. No obvious issues, but seemed like shutters were not opening (ok maybe that's obvious). Pulled them, used a torch to heat up thermo power unit after soaking in oil, seems to work. I guess I'm looking for either...
