There have been several posts recently about Do It Yourself rebuilding of carbs. I can take off, soak, reassemble with new kit and synch the linkage on my twin suzuki 140 2strokes. They have 4 inline carbs each with only one long adjusting screw per carb. The book says to gently seat the adjusting screw and then back out about 3/4 a turn. I think that is to get it close enough to crank, but I would like to hear how some of you then fine tune the adjusting of each carb. On cars, I would turn it super slow in or out until it makes a better difference listening by ear. Same thing with the boat? I am always worried I will get to lean and burn a cylinder.
I think there is a vaccum gauge set-up for fine tuning multiple carbs to “balance” the cylinder performance.
Bring on the 2-3 chop!
With my 70 HP 'Rude, the manual said to adjust all three the same amount, waiting 15-20 seconds between each adjustment of 1/8 turn. IIRC, mine was to begin @ 2-1/2 turns out…I’m at nearly 3 full turns now to maintain smooth idle, but each motor is different.
Thanks,
I think the correct way is to slowly go in or out with the same amount on each one. A tiny bit at a time as you stated.
Thanks for the replies.
