Well, I don't even know where to begin with trying to figure out what the heck is wrong with my truck.

I took it out today for the first time since a few tanks over Memorial Day weekend, and I could barely get the thing started. Once I did manage to get it started, it wouldn't stay running for more than a couple minutes without dying. Usually I would just give it some throttle while it was on the stand, then I would hit the brakes, and it would immediately die on me.

I did manage to get it to run long enough to get a few laps in through the parking lot, but literally by the time I would bring it over, then bend down to grab my temp gauge, it would shut off.

All my measurements never got a single temperature over 145*. Obviously, once it's had time to warm up, it should get much hotter than this, but even letting it run on the stand for 2 or 3 minutes would not put the temperature over 145*.

This made me think it was running too rich - I have always run it on the rich side, but, if I leaned it out even 1/4 turn, it wouldn't start, acting like it was starved for fuel.

Then when I would richen it back up, it would bog down when I tried to give it gas, and if I kept on the throttle it would power through and give copious smoke at WoT, but then usually it would shut off as soon as I hit the brakes again. Is it possible that maybe I just need to lean it even more?

I have never had any real problems keeping it running once it was started and warmed up, and it ran with no problem the last time I drove it, but the same settings today (very similar conditions) were not even close.

And naturally, I tried to get some videos with my Blackberry (which is REALLY hard to do when there is only one person there), but those are currently not working for some reason. I will try to get them up.

In summary - when I could get it started (I usually had to blip the throttle with the igniter on and the roto-start spinning to get it to fire up), it never stayed running for long.

Any ideas would be very much appreciated, I am at my wit's end with this thing. Thanks.
 
I have not changed the idle settings at all. As for the glow plug, it's an O'Donnell Medium and it's only about 5 or 6 tanks old.

I did remove the glow plug to examine it and it looks REALLY wet, which again makes me think it's running so rich it's bogging down, but if I lean it, it won't start...
 
adjust your idle screw..... change your glow plug... how old is your fuel... you let it sit for a while right...

This is not good news for team hamster hat.......
 
check your exaust gaskets and couplers i had the same issue with my sh my coupler was ripped and cause tuning issues up the bung hole like yours and check your fule lines make sure there not cloged or something blocking the fuel pickup in the tank also check the carb for blockage. hope this helps
 
Well, I did let my fuel sit for a long time in the trunk of my car, but that isn't the problem because I was using a brand new gallon of Trinity Platinum 20%. I will try a new glow plug and I'll replace the fuel lines too. I'll also try adjusting the idle screw to see what I can find. And, I'll check the couplers and gaskets. I'll try to get everything back to factory settings and work from there. Thanks for the input everyone.
