Weber 32/36 DGEV Float Adjustment help

Recommended Posts

I wanted you guys to look at the pictures and tell me if it looks right to you. Specs are 35mm resting on uncompressed needle valve held vertical and 51mm open. I have a little over 35mm resting and 51mm open. Last 2 pictures are with carb lid upside down with valve compressed. Does that look right? Also the tab for the open drop does not hit needle stem. Can't see it touching stem to achieve full drop. Brand new carb...was at a little over 40mm resting and around 49mm open from factory. Thanks for looking and feedback, waiting to hear from you guys until I put it back together.

This would be open

This would be needle valve vertical (pointing up) and closed. I assume the float weight would compress the needle valve I guess you could lift it with a finger to uncompressed.

Yeah that's right Mike, the first picture you quoted is open position. Measures 51mm from carb lid surface to top of float. The second picture you quoted is with the lid turned totally upside down and needle valve is fully compressed. The first picture I posted was carb lid held vertical with tab resting on needle valve(ball) uncompressed, measures just a hair over 35mm from carb lid surface to top of float.

That shit was wrong. You can tell from the 2nd to last picture I posted in my original post that the float was angled down when resting on compressed ball. If I got in in spec at 35mm it was even more angled down touching a bolt on the bottom of carb lid. The 35mm/51mm spec is bullshit. The correct spec is 18mm from top carb lid surface (with gasket) to top of float with everything held vertical held at 45 degree angle so float is resting on uncompressed ball in needle valve. Full travel of needle should be 2mm, so with carb lid inverted and fully open distance from carb lid to top of float is 20mm. In essence, when float is resting on compressed ball it has to be level.

Anybody else here care to chime in on their Weber plastic float leveling procedure and specs used. I am fairly certain  I have it set up correctly but there is so much conflicting info out there and I want to make sure it's right before I install it. C'mon people give me some info...lol I'm ocd as fuck.

I think you had it right in the first place, at least that's the way I just set mine up (not running or even installed on truck yet). I held it like the first picture you posted (same as the line diagram view), and used the 35mm measurement just as the tab rests on the ball, not compressing it, and with no gasket in place. I didn't mess with the max open measurement, so if anybody thinks that's essential, I hope they post up soon.

I hate to post when I don't feel like I have definitive info or experience, but it looks like you are going through the same process as I did, searching the web, looking on Youtube, finding conflicting, incomplete, half-assed bullshit information. This suggests the DGV works ok if you are in the ballpark, and that makes everybody think they did it right, so they post whatever they did.

For my fellow tool junkies out there, the picture below is the Weber or Redline tool for DGV float setting, plastic on the left (35mm; 88839.00.0328), brass on the right (measures just under 40mm, cutout seems to be so you can place it right over the power valve plunger; 88839.00.0325). Measured from the bottom of the leg to the crossbar on the inside of the horseshoe. I was expecting the brass float one to measure 41mm, maybe it has to do with measuring at the power valve plunger. This doesn't answer the gasket in place or not, or the ball compressed or not questions.... I'd love to see info directly from Weber or Redline.

All I know is that if I got the float at 35mm resting on the uncompressed ball, when it was turned right side up compressing the ball all the way in, the float was angled too far down and hitting a bolt on the carb lid.I just don't see how you could bend that tab as much as you have to ,  to get the 35mm measurement and still get a level/horizontal float to carb lid in a fully compressed ball position. The way I have it now is 18mm from gasket on carb lid to TOP of float lightly resting on uncompressed ball. Measurement from gasket to BOTTOM of float in that position is around 39/40 mm. Full drop I have about 2mm of needle valve travel and have 20/21 mm from gasket to TOP of float. Measures 50mm from gasket to BOTTOM of float in that position. Floats are level and horizontal to carb lid in fully resting position.

Do you get the 2mm of closed to open needle travel, as mentioned above?

Yes. The way I had it originally in my first post, there was probably 10-11 mm of travel, the needle valve was almost out of the seat.
