well thanx guys for all the info. The fuel pump is only about a year old and has about 300 gallons of gas or so through it, so i hope its not that. The jets right now are at 73 primary and 84 secondaries. The power valve is at 4.5 which i had at 2.5 but the shop put in the 4.5. And no powervalve in the secondairies.

As for the altitude, Ya i hate it, This truck was built for me buy a friend/ dad type of figure and i moved a ways away so now im having to learn very fast. Never had any trouble with the darn thing until coming up to this altitude . lol. Im a rookie when it comes to all this. One more thing i forgot to say is i only drive like 8-10 miles and i get the smell of gas in the oil, and it starts to get a little thin.

Also, how would i check if its leaking in the crankcase?

thanx guys,
david
