Question on Synchronizing carps again!!!!

Postby whiteeaglepwl » Thu May 17, 2012 5:26 pm



Ok i understand that carburetor #1 and carburetor #3 needs to match, #2 to match carburetor #4. But i think on my carb #2 is out of adjustment and #4 is out also out of adjustment. my question is how do you know or adjust #2 from scratch or #4 from scratch.Also #3 on my gauge is reading 45 lbs. i got #1 to read the same as #3 but when i try to adjust #4 to match #3 it pulls the engine down real bad and starts to knock. so dummy me tryed to adjust #2 to level it out so i think i got them all messed up on #2 and #4.I cannot get #4 the same as #3 45lbs.I got #2 and #4 to read about 25lbs , what am i doing wrong. I am about to pull my hair out on this thing LOL thanks for the help again. If it wasnt for all of you on here i would have gave up on trying to get this wing to run right,
Thanks again Phillip

I am not the best at this, but I just set mine this past Sunday. I put the idle at about 1500rpm's 1st. Them set #1 to match #3. Then I went and #2 to match #4. then #4 to match #3. After each time I did some messing around I opened up the throttle a little bit. I think that this is very important to do. I don't remember what the ready way, but I did get them all to be about the same. I read all of the how to's before I did anything the night before I worked on the wing.

Tprender has the right idea. Sometimes you need to try and sync them at a higher rpm, then try again at idle rpm. If that doesn't work you might need to rebuild them. If you rebuild them, do a bench sync before installing them. Do the same sync procedure as with the gauges, but do it with feeler gauges or a small diameter nail. This gets them in the ballpark to run it and sync with gauges again.

I sync mine right side first and try to keep the rpm adjusted close to 1000 rpm.
Then I sync the left side and again adjust to 1000 rpm
Finally sync the right to the left and set the idle at 1000 rpm.
I'll double check when I'm done.

I despise gauges.They are inherently different in their readings.I had 2 vacuum gauges that read 5'' of vacuum different on the same line.I opted for a different method.It is dead accurate any you can sync the carbs at any rpm you desire.I could get it to fire evenly all the way down to 500 rpm.
The gauges just bounced too much for me,even with dampening valves.
With this,your not looking at numbers,just a even oil level and even bubbling in each pair of bottles.

If one cylinder is off it will try to pull the oil from the other bottle.
When there synced,each cylinder draws from the other creating a balanced level and even bubbles.
