hi i noticed my truck hesitates when i drive at a constant speed i know it can be a few things like intake air leak fuel pump and carb problem if any one has had this problem can they let me know what they did to stop this its getting real annoying i order a weber just cause i like their performance hopefully it will stop my problem

 

I find that it's usually the simple stuff for me. Or it's stuff that I messed with previously.

When I finished my rebuild my engine would stumble randomly at about 2400-2800 in 4th and fifth gear. It ended up being vacuum lines, and a slight vacuum leak at the bottom of the carb riser plate. I really had to concentrate on knowing what item was what and I had to stick to the diagram on the sticker under my hood. The ones in the manuals I had were confusing as hell. At seemed to be missing parts. Verify and double check that's all good.

Fuel filter? Plugs, cap, rotor? Timing?

I'm not a good mechanic, but I know enough to look at what I messed with previously and correct the mistakes I made the first time. That's usually 70% of my problems. Actually, since the rebuild its 90%. Then I start with the simple stuff and work to the more complicated.

 

Thanks it has recently had a new timing chain so i hope that's not the problem cause id hate to ruin my motor but i will definitely check the carb I'm hoping puttung the weber on will fix it i don't want to expensive of a fix
