And I appreciate that Mr Fixitall, cause without the forum to lend a hand I'd never have started it, just left it with the bio-diesel system and called it good enough. Ran it as the POS it was till it died. I knew I'd have assistance if I needed it, and its most appreciated.
on the Pyrometer front
The ferret fitting sounds pretty easy, although it does irk me to have to drill a hole in my brand new headers. Butchered as they already are, someone should be held for war crimes on that one.
The pump only moves about 3/16 to either side of the mark on the block. Period, then it runs out of oblong hole. I started out today with it as far to the passenger side as it would go, ran like two dogs *******. Then I moved it to about 1/16+ to the passenger side, ran like one dog limping. I then moved it to 1/16 to the drivers side, ran a little faster than I can, but blows a lot of unburned fuel through the exhaust system if you get after it. Course that might have happened at any point in the process. I took some of the exhaust system apart to check what kinda soot I was getting and it was soaked with fuel/oil. Lots of unburned fuel. If anything I'd think I needed to turn DOWN the fuel. Remember I'm at altitude, mile high. Denver C0 5,280" elevation and I regularly drive up over the pass, say 10,000 range. I'm a little baffled as to how turning up the pump results in higher temps. Leaning out an engine is what increases temps isn't it? Turning up the fuel should result in cooler exhaust. If someone can explain that one I'd sure appreciate it.
Anyway lots of good info in those last few posts. I'm encouraged by the sound of a light for $40 and would consider installing an EGT sensor. But I've got to prove more power is available before I can really consider spending any more on this thing. Yes it drives the way it is, but hauling anything would be pretty grim and I built this thing to haul lumber back from Missouri to CO.
I'm inclined to want to turn the pump down not up. The reason I might have so much unburned fuel is likely a poor air fuel mix. I'm pretty sure this thing is purely mechanical IE no computer, so adjusting for altitude must involve turning fuel up or down. In this case it seems like down is my best bet.
