Mikuni Carb tuning help

[510love]

I screwed the idle screws/valves all the way to the right and then did a quarter turn to the left ( unscrewing ) hoping to re-tune the carbs.....well i failed and now have big 1969 datsun 510 paperweight......i sat there for like 2 hours trying to get it to kick over..... so how many turns to the left ( unscrewing ) on the idle screw is idling? thanks for helping me through my fail.......:D

I'm lookin' at an original Toyota 2T-G repair manual (factory Mikunis)... it says 1 1/2 turn from fully closed.

1.5 turns out SHOULD get you started, but it will depend on your pump and idle jet size too. Has the car run before with this carb set up? PM me if you want some more guidelines if you are having trouble.

What you have performed is simply a baseline or 'bench' setting. It should be about 2 turns, not 1/2 turn.

 

But even that will not be right. Once you get it running and fully warmed up, adjust each mixture screw for fastest idle. Keep turning the idle screw down, and adjust the mixture until it is right on.

did you rev it up with the screw's where turned in

are you getting gas to the carbs? Those carbs are very friendly....seems something's wrong on the fuel deposit.
