Carb Balancing by "highest idle" instructions?

[gk45011]

Help

Steve or others. I know where the fuel/air mixture screw is. CAn someone please point out the synch screws??

True enough. You need to to a bench sync, which is just checking visually that the carbs are open about the same amount at idle speed, then do a dynamic sync using gauges. THEN you can check the idle mixture screws by using the highest idle method.

Here is what you are looking for on the bench sync. Notice the openings under the throttle butterflies.
Adjust the sync screws between the carbs so the sliver of light is as close as you can get from one carb to the others.

#3 carb is the fixed carb, all others are synched to that. See the adjustment screw in Steve's picture that is between the two carbs. There is a special screwdriver/nut tool that is extremely helpful. Has long shaft to reach in and adjust screw while loosening and tightening the lock nut. Here's a link at Z1

Those cheap sets are fine - the needles only jump around if they're not damped. We used to use the Kawasaki sets rather than the Suzuki gauges as they were easier and the Kwacker set were dial type, almost the same as those cheap ones.

You can pay a lot more and get the Davida dial type gauges as well. They work, just no better than the cheap set - if you damp things down.

Yes they are fine once setup properly. You have to trim the dampness else the needles will bounce but that is part of standard setup. I have had. Two problems. Rubber vacume line is cheap and tends to split. I have had to cut back the ends a fee times. Also the brass extensions work well but can start to come apart. I use some solder and soldering iron to sweat the ends into the tubes to stop them fondling spart. Had mne for 4-5 years and both chef1366 and myself have used them for balancing podded carbs

Sorry about that.

I looked at the thread, then had to go do something else. Came back and posted a picture that I had saved from a previous post quite some time ago, apparently using the same picture that you did. I already had it done (but not in Photoshop) and posted to Photobucket, but did not see your post until after I had posted mine.

There are times that you don't really need anythng fancy, good ol' MS Paint works just fine.
