I finally got my truck running and out on the trails. Ran good until I started hitting some bumps. It kept on spitting and sputtering then it would stall. I mean every little bump! Its a 22r with carb that i think is a Webber. Not sure though any suggestion would help. I'm considering propane but money is a problem right now. Thanks

Save your cash and get rid of that weber, I have a Webber 32/36 and I hate it! It's the probably the worst thing that was ever put into my rig. If you don't want to do that, check your fuel pressure and consider getting a manual for that carb. Webbers don't really like the factory mechanical fuel pump because the fuel pressure varies and is probably too high. They have a tendency to choke on inclines. Check out Redline carbs online for all kinds of info. I finally got mine running o.k. after switching over to a 15 psi electric fuel pump mounted on the rear crossmember over the driveshaft and a 3.5 psi regulator, along with sealing the float chamber, drilling another hole with a vent to a vapor canister and adjusting the float level, fuel jets, and air corrector jets. If I do plan to keep my engine at all, I will be looking into a Holley Truck Avenger carb with a LC engineering intake to match it.
How does it do on the road? What kind of tire/gear setup do you have? Just curious...

It has 33s and whatever stock gears are on the 83s. I don't run it on the road it is a truggy. Full roll gage and everything. I race it in an extreme obstacle course here by town. It ran strong until it started to bounce then i couldn't keep it running. I have a holly external fuel pump with reg. but i didn't check the psi because i don't have a gage and didn't have time. I finished the truck on friday and raced saturday. The carb looks old so i was thinking I should get a new one, where can i go to look at the holly carbs? I found a weber 38/38 for $400. Thanks for the info!!!

If it's offroad only I would spend the cash on propane! I don't think LC has the Truck avenger carb, they just sell a regular carb which would need modifying to do well climbing offroad. I would call Holley and ask them. I tried sending LC and Holley emails asking about the Avenger but apparently they don't really respond to emails. I think there is a 470cfm Avenger and it is the smallest, but I would ask them if it will work well with our engine first, you might need a smaller carb, like a 350 since I don't think the factory carb is over 300, it's 2xx. I was thinking it would work because LC sells 500cfm carbs for our engines as well. Let me know what you find out.

Ok I emailed holley and so far no response. LC emailed me back and said that the weber 32/36 or the 38 would be the best bet, what do you guys think? Thank you for all the help!!!!!!!!

Upgrade your exhaust and Cam to get full enjoyment from your carb. 38 way to big for stock, in my opinion.
Later

Check out Jeg's or Summit Racing for Holley (and other) carbs.
Holley makes an offroad carb (model 8007, IIRC), 390 cfm is the smallest size, which is too big for a 4 cyl. It's meant for a 6 cyl (I run it on the Buick 231 V6 in my p/u).
I don't think the Truck Avenger comes in a size suitable for a 6 cyl much less a 4 cyl, but I haven't checked recently.
As for your current carb, could be float adjustment, weak spring on float or needle, etc...
