Basic bench carb balance

(1/3) > >>

Bryanj:
This is to bench set carbs that have been completely disassembled or adjustment altered wildly


First undo the main tick over screw out until there is no thread showing past the bracket and there is a gap between the end of the screw and lever on carb.

Pick a carb, needs to be the one with the lowest slide or the no adjuster if there is one.

Make sure that the slide on the carb you picked touches the base of the body, if not use the adjuster to make it touch.

Find the smallest drill bit you have, must not have a chewed up shank, 1/16 inch max and turn in the main tick over screw until the shank of the drill just fits under the flat side of the slide.

Using the drill like a feeler gauge set the other slides to the same height, using the individual adjusters.

You may need to undo the tick over screw to get the bike to start but this will give you a good basic setup.

This does not set the high tick over found on PD carbs these I try to stay away from as much as possible.

Hey, quick question... do you do the measurement with the drill bit from the air side or the engine side of the carbs. Thx

Bryanj:
Engine side, it has the flat bottom not the cutaway

K2-K6:
Thought I'd bring this original topic to more current listed.

Also to add some detail from another to help with assessment/recovery of wrongly set carburettor with them in situ to at least get someone back on track without stripping carbs from bike.
