weber 32/36 disappointment

I just installed a new weber 32/36 and to cut to the chase it pretty much ****s. The motor is stock eccept for HEI and compression is great. Though the original carb never really worked right I have to say that all I did was change out drivability issues. This thing has a hole in the power band so wide my wife could parrallel park in to it. Has anyone rejetted theirs with any success? Would anyone be willing to share some jetting swap info? I undrstand now that two would be better but thats alot of $$. So any help with getting this thing drivable would be great. I feel as though I lost 20hp from a motor that did not have it to spare. It idles great but hs no power I need to start it in low and shift it to drive after the rpms get up there. I removed the air cleaner to see if it was lean or rich. The bottom got better but alot worse when the secondary was open. At $7.00 a jet i can not buy a series of them so if someone has fiddled with this weber and remembers the sizes they had succsess with please share.

 

Folks might need to know a little about the engine it is on.

 

Totally not what I want to read after installing one myself.

Where did you get it?

Mine came setup ready to run out of the box set for my 230. I can't ***ess the power loss/gain until later this week when the new exhaust is installed.

I wonder if adding headers will help your application.

There is a book. It is about tuning webers. It has a graph that allows a gearhead to figure out how big the main jets, venturis and idle jets need to be. That will get you close. But you have to read the book. I tune webers for folks..mostly side draft units but the 32/36 deals are like about the same. Hope you have it on a small engine. A 32/36 is good for a 2.0 or smaller 4 cylinder...a lot of VW guys use them on the 1600 cc bug engines and some guys use them for the street on 1500 cc british engines.
Feel free to pm me, I will try and help ya sort things out.

 

It is a 235 I read on the board here that the lower Cfm of this motor would make it an ideal upgrade. I fear that now that the pod bar has been made a 38 would have been a better fit. I purchased it from carbs unlimited

 

Purchase has been made. Not pob bar. Fat finger syndrome

 

I'd guess you might need another. I ran a single 32/36 on my Datsun 2.0 which is about half the size of your motor. it ran great and I never even touched it after I bolted it on.

 

I think headers would exasperate the situation. Inliners state that 32/36 for stock motor 38 for any mods.

 

I'd suggest calling Tom Langdon from Langdon's Stovebolt.

 

I probably should have bought it from him

 

well I just want to give an update for all interested parties. I ditched the weber 32/36 and installed a 38/38. I have been jetting for a week to get half *** drivability. Bolted the 38 up and I did'nt do **** to it(yet) smooth as silk. to hell with gas milage( until the card declines) drivability is what I was after and by joe I got it. recomend 38 over 32/36 to anbody.I know langdon knows his stuff but for my motor , for what ever reason, loved the bigger carb. peace at last.

 

Yup. The 38/38 is both barrels, all the time. The 32/36, regardless of jets, is just too small for a 235. I run a 32/36, and, at 32MPG, I love it. Of course, it is on a 144.

 

I ran a 32/36 on an old scout I had with a 196 with a carb adapter from Landon's. I was totally happy with that carb. Electric choke and Electric fuel pump, that thing started almost instantly everytime. I think you just got a bad carb.

 

you may be right hillbilly, I may not no too much about webers but I am no stanger to jetting in general. I believe I would have gotten closer to where i wanted to be by now. Granted I think the 38 will need some fine tuning, albiet w/out a air/fuel ratio meter. Seat of my pants tunning, slowly going through the throttle positions.
