What is the optimum float level setting in relation to level in main jets.I have read from 1mm down from the nozzle tip to 1/8 or 1/4 below to at the top.Trying to sync both levels to best position.
Thanks
Tom
 
The float is set using a 7/16" drill bit or rod. The static setting for the jet is set by running the jet up level with the bridge, the wind the adjusting nut down 2 turns, or about .062" if using a dial caliper. The fuel level in the jet should be approx. 1/8" below the top, not real critical.

Thanks Berry.I wanted to use the height in the jet because I am not sure if the needle/seat parts are original spec.
Thanks

Tom-I think that as long as you use the 7/16" rod to set the float level, any difference in the needle/seat won't affect the fuel level in the jet. I kind of wondered the same thing as there is difference in length between the Grose jets and the conventional ones.

Hey Berry.Finished earlier with adjustments and the levels are now even in both jets slightly below the tip.
Car has been running great but I noticed the different levels cleaning the carbs.
I don't see how a different height close off for needle and seat assembly would not effect float level.Mine looked slightly different in height with the shorter(barely noticeable)front having the higher level,although both are the same,spring dampened needle assembly which appears to be threaded into seat.Not sure if that's OEM.
I have rebuilt lots of vintaqe MC carbs and never have good luck with a dry measurement,maybe because of slight differences in repro float buoyancy or needle and seat parts.
Anyway I believe the end game is correct level in the nozzle so that was an easy way for me to gauge.
I also went from the 20/50 engine oil in the dampeners to auto trans fluid and it seems a little snappier.
Thanks
Tom
