Reply to "Carb sync-ing"

Come to think of it, maybe you can use this as a great educational opportunity:

You now seem to have it running to your satisfaction at idle and (hopefully) at 2,500 with the washers on the idle stops, which, BTW, I'm OK with.  Take it out and drive it and see how it performs.

Then, try running all of the bleed screws out 1 turn and re-sync everything at idle and at 2,500 rpm.  I would be curious to see what effect you see in twiddling the bleed screws when running at 2,500 - do they only affect the low idle or do they have significant effect at 2,500 rpm?  Please let us know the result if you do this.

Once sync'd with the bleed screws somewhere around 1 turn each, take it out and drive it and see how it performs and report back on any differences, positive or negative, that you feel.  

Reading Tomlinson's book on carb "theory" is one thing, first-hand experience is a whole 'nuther thing.

Don't make me go out into the garage and start twiddling with Pearl's bleed screws just to see what happens.  I am known to really screw things up once given a screwdriver.......

Thanks,  Gordon

It's much easier EXPERIMENTING with the people's carbs isn't it Gordon?
