NOVICE ALERT!!!! I have not owned this truck long. I have no business owning this truck, except that I do want to learn. Assume I know nothing. Thank you for your patience.
Right, so it's got that DGEV carb on it, has been backfiring since day one and has finally gotten bad enough to drive me to post something after annihilating my muffler. Sick of it. Joe mechanic says "You got more carb than engine" but I see a lot of these swaps; seems like the thing to do. Put new gaskets in but of course that did nothing. Tinkered with that mixture screw and that idle screw to no avail. That's the extent of my understanding.
Here it is, I'm suspicious of the big hose coming off the filter housing and into the the top of the engine. That just doesn't make sense to me. If that's right, can anybody tell me what's going on there?:
(I'll figure out pictures, heres a link:)

Anyway, what's happening, what am I looking for, don't make fun of me, I love you all, and thank you very much!
Oh, and for future reference, should I post this in "engines" or "620" like I did?
