Bench Sync

[Steve]

Where exactly am I putting the paper clip to test the drag? I'm having a hard time visualizing it.

This is talking about the butterfly valves isn't it?

Go ahead and use a "paper" clip (they all seem to be made of metal ) if you want, but be aware that you stand a chance of scratching the bore of the carb and also not getting it right.

Because the space between the butterfly and the throat is an arc, the size of the opening depends on how far off-center you have your METAL clip. If you have it a bit off-center, you will have to open the butterfly a bit more to get the same gap. That is why I recommend eyeballing it with a light on the other side of the carbs.

The other part of the benck synch of course is the mixure screw setting.

I have read thatthe screws shoudl be backed out 2 or 3 turns from the seated position, but can someone please confirm if that's three *full* turns out (ie three x 360 degrees) or three wrist twists out ... which end up being about a half turn each.

I would like to think 3 turns means 3 turns, but my experience with webers in the past tells me that this isn't always the case.

Thanks

I have used the paper clip before, but this last time I just used light coming through the venturi (no slides installed) as the flies just started to open. I was able to get them very closely synced that way.

CONFIRM.

That is three FULL 360-DEGREE TURNS.

How much does a dealership charge to sync carbs?

Much much more than it's worth and you'll likely not get it back running the way it should.
