I've been fighting low power since I got the truck. I think it has to do with carburetor and the choke opener not allowing the secondary to open. Is there anyone else out there that has had this problem? I've checked all the basics and this is what I have come down as the problem. Any ideas on some possible solutions? Thanx.

 

There are alot of vacuum operated parts on these carburators, check all of your vacuum lines, make sure there hooked up properly and there are no leaks, when was the last time your truck had a complete tune up ?.
