Redline Weber ICT Kit Question - Parts?

Chris070780

I received my Redline ICT kit. I Bench assembled everything and took inventory of parts. Kits seems to have a lot of things in that I'm not aware of what they are for nor do the instructions do a very good job of outlining what they are for.

Spring washers? What are they for and are they needed?

1/4" hose was included and a much smaller hose. I assume the smallest hose is for fuel? I also have two T-adaptors. One fits 1/4" hose and the other fit the smaller house. Is the larger tube for a balance tube if one wishes to add? I was very surprised to see there were no provisions for a balance tube. I guess if I sync perfectly it’s not needed.

So what is the spring washer for?

March?

How big is the washer? Is there only one?

There are 8 total. 4 black ones about the size of 13mm bolt would slip thru and 4 silver ones about 10mm size. The bigger ones look just like spring washers on throttle arm of 34pict carb

My guess is that 4 of them are for use under the nuts that hold the manifolds to the heads if you don't already have washers there. Don't know about the other 4.....

Yeah, I was thinking that and to hold the linkage brackets to the carbs, but those washers are huge.

Maybe the larger ones are just replacment ones for carb shafts. Strange. Instructions are horrible when it comes to parts list. I purchased these from ac.net to get them setup but after studying the cb performance kit I think I would have got that instead. It looks setup much nicer than redline.

CB Performance has installation and tuning instructions in the tech info section of their website. The article on the ICT's is here:

I connected the small hose between the vacuum ports on both carbs, kind of works like a balance tube (I guess). I tee'ed it off to my SDVA distributor. I just used the instructions to tune my dual ICT's with outstanding results.

I can just pull vacuum off left carb right? No need to draw from both carbs?

I seems to me they run better with the vacuum ports of both carbs connected together.

The carbs as they are built are incorrectly jetted for the VW engine. The jets as installed are: idle 52 and main 130. For two years I couldn't get the carbs to run right and I finally (recently) replaced the jets. From the recommendations I found here on the forum I changed to a 60 idle and 140 main.

The difference is like night and day.

I also had problems with the crossbar linkage, switched to the SCAT push-pull linkage.

I had Aircooled.net pre-jet and clean them. with 57.5 and 140's. So its set. I might just go ahead and draw vacuum off both carbs. Do you have the Redline Weber kit or the basic Weber kit?

I bought my kit some years ago at the east coast BugOut. I think most items were Bugpack, and the crossbar linkage would bind unless I added another spring. After installing the SCAT push-pull linkage, it works fine with the supplied springs.

One note, if you tighten the throttle shaft nuts too tight, it will cause binding. That's the reason for the washers with the tab on them, bend the tab over the nut so it won't loosen.

I knew next to nothing when I bought the kit. For two years I've been fighting the engine not running right, until I jetted and tuned them correctly.

Redline updated Linkage I think from the original weber design.

I'm curious on others thoughts about running vacuum off of both carbs if it’s truly need or not. I thought I read the left carb was fine.

Running ported vacuum for the advance from one carb should be fine. I think it would be similar to using one barrel of a 2 or 4 barrel carb on a V-type engine with an isolated runner manifold.

Running ICT's on the 1835, had them on the 1641 (same cam a 110) with the cheap Chrome linkage. Got the linkage to work and jetted to 60 idle, 140 main and factory Air Correction jet. Runs great in the 1835 with no changes in jetting. Now if I just had a set of 40 IDF's for the 1835. YeeHaaa Laughing
