92 B2200 replacing vacuum lines

I've got a 92 b2200. Had carb rebuilt, can't get anyone to check out vaccum lines. Truck runs terrible. I've decided to replace the vacuum lines and see if that fixes the problem. Some of them are toast. The truck has been sitting on and off for the last 10 years. I'm calling it the "phoenix" cause I want to bring it back to life again.

Welcome to the site man! Vacuum lines are a big deal when dealing with carbs and if some are plugged or cracked/split and leaking then that could be the issue. Do some searching through threads on here maybe in the repair section you might find what you're looking for. Ever though about upgrading to a Weber carb?

You try this?

Throw that carb a way go buy a weber. Never worry about vacuum lines again. ..

I will definitely get a weber if I can't get the lines right. Spent $350 on a rebuilt carb so don't have the funds to get a weber now. Thanks to all for the info. I will definitely check madza trucking site out. Appreciate the help!
