carb sync again?

[ratiug]

I recently pick up a 95 XII , it ran a little rough in idle . So ,I drained carbs, New fuel filter , synced carbs, ran a few tanks through with seafoam, still wasn't as smooth as I liked, as I was installing new NGK Iridium plugs, I found one of the old plugs on cylinder 1 had practically no gap, Installed New plugs and runs much better, my question is , Do I need to resync the carbs? Though I probably know the answer , I just want to be sure, Thanks

Man, I hate spell correct!

I believe the carbs are balanced by using #1 as the base which the others are made to match. In other words, yes, re-balance the carbs. It's the only way to be sure. Cheers!

Sync carbs 1 & 2 to each other. Then 3 & 4 to each other. Then sync them all together using the middle adjusting screw.
Easy to do. I use this gauge for adjusting carbs http://www.carbtune.com" onclick="window.open(this.href);return false; Best I've used

If syncing hasn't improved performance you may need to go through them again making sure every tiny jet hole has been unplugged.
