TheSamba.com :: View topic - Help with rebuilding Weber 34 ICT shafts and parts kits

Thu Jun 06, 2013 10:31 am

I have a dune buggy that is supposed to have a built 1915 in it. If I remember right, it did have 8 dowels in the flywheel. It has been more than two years since I did the clutch. I have only had the car out twice. It seemed to run fast and was responsive.

It has two Weber 34 ICT's which are stamped maid in Spain with "TIPO" under that. It also has a "6" stamped in the same area of the carb, at least on the first one.

This carb is nasty and wasn't flowing fuel to the driver's side cylinders. I did a quick and dirty clean out while at the off road vehicle area last time. When I pulled it out of the trailer last weekend, it was dead on that side again.

I disassembled most of the carb so far. I still need to count the turns on the screws and pull the jets. The throttle shaft has play up and down and side to side (in all the wrong directions). I pulled the shaft. It looks like the threads may have banged up the holes that the shaft goes through, so that could add to any problems with play. I haven't torn down the other carb yet.

My plan was to buy rebuild kits and then clean them up and run the carbs again.

Where is the best place to get rebuild kits? Is one kit more complete than others? I live in SoCal (near San Bernardino) but I may just mail order the parts. I don't go to the Orange/Anaheim area anymore, otherwise I might hit up a few shops that are there.

Who do you recommend for shaft bushing service? I have a milling machine, but I have never done shaft bushings and I don't want to screw it up.

I have read a bit about Glenn, on this forum, but his web site didn't list carb work, just distributors.

It would be nice to know what parts are really in my engine, but I am happy with it just hauling but across the desert.

Are the 34 ICT carbs big enough for a well built 1915? My budget is low, so I'm hoping these are not holding back the engine.

Thanks guys,
Chris

If you have a healthy 1915, (decent cam, heads, and exhaust) the ICT's are holding you back for sure. I'd look into a set of HPMX/IDF 40's, or 36 Dellortos.

I will look into better carbs for the future.

This engine sounds like it has a decent size cam, but I have nothing to compare it to. The exhaust is a set of headers with a stinger. I want to quiet down the exhaust. I don't know if a quiet pak system would hold it back too much or if I should find a performance muffler. My stinger is held on with springs, so I am guessing I need a different header to run a muffler.

Right now I run on hard pack in Barstow and at Ocotillo wells. I have paddles but need to buy new wheels for them. It sits with all terain tires right now. I plan to buy suspension seats to help with the beating that I get, maybe from a manufacturer that is in temecula, ca. The car is an IRS and appears to be stock suspension. Rear tires are 33"

I might be able to find the paper that had the advertised specs for this engine, from the guy that sold it, but that doesn't mean they are correct or honest. I think I will have to keep the webers for now. The car weighs 1320 pounds and moves pretty good. I weighed my toy hauler and truck with and without the car, on the same day.

If this was a small block chevy from the 70's to 80's I would feel right at home, but I am new to vw's. I actually thought I would never own one.

I have already learned that smaller isn't cheaper. I bought the car with engine, and trans, for $2k. I put thousands more into it: front brakes, front wheels and tires, steering box, clutch, custom gauge panel, rebuilt front king pins (is that the right name? its been a while), rewired all electrical, etc. The previous owner claims to have spent $5k on the engine and $2k on the trans rebuild.

My short term goal is just to get it running an comfortable to go out and have fun with. Of course, with a small block chevy, in my pickup, that could produce 525 ft. pounds of torque, you know I will want to push the vw just as far.

Maybe I should just have kept my dirt bike and taken a chance of breaking my leg again. :roll:

The ICT carbs are certainly rebuildable, you might try contacting Jeff's
Kaddie Shack and see if he will bush them for you. He specializes in Kadron's
but a carb is a carb. Speaking of which, the ICT carbs are not a great choice
for an offroad car. I ran a set on my sandrail for a year but very quickly
changed to Weber IDF's as the ICT's did not like the rough stuff at all. You
might want to consider a set of Kadron's, they are relatively inexpensive,
very durable, and easy to find. As stated before, Jeff is a Kadron specialist.
I run a set on my DD Baja, and have a set on my 1776 spare engine for
my sandrail, and am a fan.

Thanks for the info. I looked at his web site. A tricked out set of duals would probably be about $900 for the whole setup, but they sound nice. I will give him a call this week and see about doing the shafts on mine and I will consider his IDF's for a future upgrade. The ICT's ran pretty well, but I have stalled the car on big bumps and I have only driven this VW. As long as I don't get to drive another VW before I can upgrade carbs, I should be ok with what I have for a while :D

The problem with ICT's is they don't have bushings to begin with, the shaft is just riding in the carb body, they just a cheesey little seal that wears out pretty quickly.
I would think any good machine shop could do it for you, I had Mark Harney do a set for me a couple of years ago but he is not doing any work on carbs any more.
