YICS Tool Rental?

umm...you do know that chacal sells an aftermarket version of the tool for not a lot of money, right? And that it works?

 

Didn't know that, but I was going to PM him about it. Thanks Fitz

 

ok stupid question but what is this tool used for?

 

If you have a YICS engine it blocks the ports so you can sync the carbs. The YICS (in simplest terms) is a passage that allows the carbs to share vacuum.

 

ok very interesting because i have a yics engine. i think i might try to fabricate one of these tools then, i have a guy with a lathe also il have to takea closer look at the the diagram to see if he can build me one.

 

Is it me or did everyone in here miss Rick saying to stuff it with mystery-oil-soaked t-shirt and plug it up?
Sounds good to me!

I trust Rick so much, I think I'd trust him to do heart surgery on me.
Well, maybe not HEART surgery. lol

 

Wait until you actually do the stuffing. It is a royal pain. The tool is easier. I tried it and it does indeed work.

 

And to un-stuff the wadded up tee shirts, I tried picking them out with a litle hook I made, and ended up driving them thru with 2 Chevy push rods
and a hammer. If you stuff it, tie knots in it.

I'd like to thank Polock for giving me his YICS tool.

 

ok,stupid question coming on. been reading all bout these carbs and the issues so i could better understand it all but this yics thing is a gray area in my brain at its not brain matter.LOL, anyway where does this tool fit to block the yics ports? that is the only thing i havent figured out yet?

 

On either side of the head, at the rear, just above the joint with the cylinders is a flare-nut bolt head with a copper gasket under it. These are the plugs at the ends of the YICS passage. You remove one or the other to insert the tool; both to clean out the passage.

In this picture, it's visible at the VERY BOTTOM of the pic, just behind and below the fins on the head:

 

ok now i got it thanks!!!!!!!!

 

Hi all. Anyone seen this YICS tool on ebay? Any thoughts?

ebay

The o-rings are Viton and withstand almost 400 degrees. I wondered if it was worth a look or not?

Hope you all have a great weekend!

Just a logical thought, no experience. . .
Since the "O" ring only seals while compressed, you are shoving this precision tool in, and the "O" rings are scraping against the sharp edge of the smaller transfer ports, with the possibility of cutting these "O" rings.

The tools we use/build expand the rubber seals once in place.
If it doesn't ruin the "O" rings, then it sounds fine.

 

I got one of those it works ok but as TIMEtoRIDE the "O" Rings do get cut and dont always seal. I thinsk thte tool from Chacal is a better buy.

 

Hey guys, I tried Rick's t-shirt method and it worked like a charm. If you have trouble getting it out when you're finished thread a wood screw into the wadding and pull it out. Presto! Unplugged. Just be sure you're threading it into the wadding and not your engine.

 

Got any more info? How many t-shirts did it take? Did you have to cut it up? What kind of oil did you use? Was it hard to get in? Why am I asking so many questions?

 

I just cut two 1 1/2" x 3' strips, soaked them in motor oil, and packed them in the passage a little at a time with a piece of threaded rod I had laying around. Anything long enough would work. I agree that getting a tool would be easier but if you're not going to use it all the time why not use this method that doesn't cost anything?

 

I'm renting strips of oily "T" shirts, but I need a big deposit :lol:

 

TIMEtoRIDE, how much do you want? Do you ship to Canada?

 

Is this the correct reverse engineer of the YICS tool?
Sorry to hijak so to speak. Didn't really see the point
in starting a whole 'nother.
