32/32 project on my 1100

[SJBikesaws]

So first I tried a 32/36 on my gl1100. Jetted it to as close to perfect as I could, but still had a lagging flat spot but tons of top end. TO BIG!

Next was what I have on it now, a 28 pict solex. Runs perfect, until it runs out. TO SMALL!

Afetr reading through this thread http://www.ngwclub.com/forum/viewtopic.php?f=47&t=49727 then I was on the hunt for a 32/32 weber, which is tough to find, but I got a reman one,,,,,,for about $65 on ebay.

It was listed as: ROS 1981 FORD/MERCURY FOR 1.6L 98 CI ENGINE 2 BARREL REMAN CARBURETOR and the guy shows to still have more than 10 available. I couldn't really find out any specifications for the carb, so it was a leap.

Sure enough, when it got here its a motorcraft branded weber 32/32. Looks like I have quite a few vac ports to plug, and 2 solonoids to either modify or remove. I believe they are both fuel shutoff solonoids and I might use both, not a bad idea since my tank is a gravity feed.

Here it is next to a 32/36 weber (well, most of it anyway)

Cool, please post how it works for you. You are high elevation if I recall?

It looks like this carb originally had a factory sealed idle screw, the rebuilder company removed it.

Here are some pics, some with some carb numbers:

YES, 9286 feet at my house, 4200 foot in the town I ride too often.

Here is the leaky old POS I am replacing. It came straight off an early 60's bug in my friends junk pile, all I ever did was open it, and see that when that bug sopped running that it was stone empty of gasoline (and clean), bolted it back together, and ran it. It really runs good, and the jetting is bone stock, but I am after a little more umph.

It is sitting on a Scat intake that is set up for a weber, with a home made adapter plate right now. So the weber is already a bolt on for me.



All that is going to slow me down on putting this together is the massive snow storm that is coming in tomorrow, and running a snow plow or front loader pays my bills, so it will probably be next week some time. But hey, did I really want to test it in a snow storm anyway????

Here is my old Scat intake so you can see it better, I pulled it from an old baja bug. Very cool intake, and the only one I have ever seen. And it will NOT fit under a stock frame, it took a really tall backbone to make it work. Just putting this up so nobody relies on me to know what intake to use.

Just something I found on the web, I am putting it here for reference.

It looks that the solenoid by the inlet is a bowl vent shutoff solenoid, so that will be gone. The one on the front is called an idle stop fuel shut off solenoid. I think it stops flow from the bowl to the idler jet, probably to control dieseling, so I will probably modify/remove it too.

I have the same carb ... it is not perfect as in jetting .. but good enough to run decent ... I have gotten mine to run really good ...the biggest reason why is the weber copy like you have will accept all the jets tubes and air bleeds that webers DFT-DTFA dose....once I figure how to work the carb and got rid of the auto choke and epa power valve and that solenoid shutoff deal and it was all just strait carb to dial in power really started to come in ... it surprised me how far off the carb was ... I see you use rubber hose me too with no problems what so ever ... ive never seen one done with the manifold you have be watching this big time ..mine the type4 plenum....good work sean

I wouldn't expect jetting to be right out of the box, though it does happen sometimes. When I put the solex 28 pict on mine, it was stone perfect for my riding conditions, which usually means 2 jet sizes leaner from anything that will run right at sea level.

If this carb was too lean for your bike, it might be right for mine. Of course, no way to know until its bolted up and running. Luckily, I have a good pile of weber and solex jets, and a set of jet drills.

Any tips you could give me are greatly appreciated, this carb is all new to me.

Looks like I have to hog the mounting holes out to fit my manifold, no problem

Well, I have been out busy for a few days, so progress will be SLOW. I run a snow plow and business has been good! And I guess that riding wouldn't be that much fun right now anyway.


I have been messing around with it a little bit. I don't have to lose the electric choke on my setup, I have tons of room over a stock set up, so I am going to try to set up the electric choke, if that gives me problems then I will put a manual cable on it.

I have also been trying to do a little research on this carb. Looks like people have had problems with the power valve, the fix is to block it and fatten up the jets. I have this as an option later, but I am going to try to make the power valve work first. It looks like people have had vacuum issues that cause it to pulsate. I was going to try a lighter spring on the power valve so it can operate off the weaker vacuum if it does give me problems. I am using a different intake than most with much more volume so I might not even have that pulsing problem in the first place. I have removed both solenoids from the carb, I had a plug the size of the idle stop, and just completely removed the vent solenoid. This carb also had a restricted fuel return, I have plugged that. My system is gravity fed so I shouldn't have a head pressure/ vapor lock problem anyway.

I also am trying to find out more about the altitude compensator from the 81 escort, It seems like a controlled vacuum leak. Since I ride from high to low elevation I would like to give it a try if I can find the pieces.

that's a bunch on the table .....I am definitely on the other side and do take all the non adjustable stuff off ....im right now stripping all the stuff off a carb ...very interested to see where this goes

[SJBikesaws]

Not a big deal, I have time to mess with it, and I have a solex that works great in case we have a nice weekend. As long as I keep it a bolt and swap operation, I won't be left with out a bike in between messing with the new one. I'm just hoping I can make it run as good as the solex on the bottom end. The carb on my ride is just super easy to swap so why not.
