This Thread is Featured in our Tech from our Forum Members section!Ok, so I have a Weber 32/36 DGAV on my 81 4x4. The Weber works great on the 22r, and picked up a bit of pep and the driveability is loads better than stock. Even gets 18 MPG much to my surprise. Unfortunately, the Weber really does not like going up hills. Deciding this was unacceptable, I took it upon myself to remedy this situation. The problem is the location of the bowl vent. When the truck tilts back, the fuel spills into the air horn, making the truck stall. To fix this there are three things you need to do. First, make sure the float level is AT MOST spec height, preferrably 1-2mm lower. Second, install a fuel pressure regulator. I use this one:and it's set to 2psi. NO MORE.Third, you need to relocate the fuel bowl vent. This is the hardest part, and the one I'm going to focus on. To relocate the bowl vent:Remove the top of the carb.You will notice a couple of rectangles that pass through the top. One of these is the the bowl vent. It is the one closest to the fuel inlet, furthest from the choke tower. You will need to plug it. I used JB Weld. Here:And here it is after the JB weld:Now you will need to make a vent to replace the one you plugged. Luckily there is a blanked port that isn't used on these carbs. Here's what you do.Drill some holes in the port to allow the vapors out. You will be able to see your drill bit through the hole in the end. Then you will need to vent the vapor somewhere. The fitting in the end is 3/8" inside diameter, so I bought some copper tube from ACE hardware and hammered it in.and from the top:Then I routed it to the stock carb charcoal canister (under the battery) using 3/8" fuel hose.And here's the finished product:Runs up hills like a champ now. Good luck!!!
Interesting. I need to re set my float anyway, so I may as well do this while I'm in there.
I did this mod. & it works perfect for going up hill. As soon as I point it down hill it dies. Any one have any ideas?
How do you reset the float??
if ya cant pork a princess, pound a pig!!!Lower the standards, raise the average!
Those are some huge welds!
