Yea that sounds like some of the problems i am experiencing.
I just ordered the OFNA valve so i am hoping that take care of the problems. i also got the O.S. #8 glow plug.

and i tried contacting CEN about these problems but i guess they are moving to a new location thats what i was told when i called anyway.
But if the plug and valve dont fix this thing i am going to be very upset as i just spent 400.00 on a truck that wont run right no matter what i do to the tune.
