Plugs...

[m00nst0ne69]

Hello folks,

I fired up the Revo after a winters tune up. Added new fuel line and cleaned everything a little better then usual. I put in a fresh plug and started to tune. I used factory plus an eighth of a turn the truck ran great then I got a half tank lean and overheated (310-320f) I added another eighth of a turn but the truck wouldn't run past idle unless I took off the line betweent the exhaust and the tank. I checked for air leaks or blockages to no avail. I put in a new plug and it ran well again. I have never had a plug go bad so soon. Is this common?

Have you checked the tank O ring? Those are notorious for causing air leaks.

Sure thing. Maybe I got a bad plug. I am running on a new plug now and richened up the mix a little and it seems to have helped.

YEP! if you don't have the orange seal replace it! it will just randomly tear on your ending you day. i never noticed mine untill i got a hole in my fuel tank i replaces the tank to find a completely ruined seal(probably what i thought was a hole in the tank).

Orange seal is there. Oh well.

Just seems like you are running too lean, like you said, richening it help. Did you use the SAME glow plugs?

Too lean on the low end and you might want to try a pice of about 5-6 inch pressure tubing form the pipe it will help too.
