Problem syncing carbs.

[Guest]

Hi

Rebuilt the BS34CV carbs following "The Guide".
I have 4 pods installed. Waited for the bowls to fill up. Puled the choke and it started instantly.

I can not seam to get the carbs sync at idle.
I do 2-3 then 1-2 all is perfect then 3-4 = 2-3 are no longer sync'd.

Open the throttle and they all line up perfectly.

It did this even before the rebuild.

Any ideas?

Did you adjust your valve clearances?

Last year.
I'm redoing them this weekend. I'll report back.

After you do your valve clearances, you will have to sync the carbs again.

No idea why your sync changes like that. It is common for the level to change, but it will change all across 1-3.

Did you plug the vacuum port on the carbs? The one that goes to the gas tank?
