correct float levels

In rebuilding my carbs on my 64 the manual says 1 13/64"float level and clarks says 1 1/8" which is right (i think i did them to clarks before but not sure)both agree on the float drop however!

I believe my "Line 9" Rochester Products" catalog calls for 1 13/64, but you should be OK with 1 1/8.
A tip from when I lived in Rochester N.Y. in the 1970's. A family friend, Frank Mason, Rochester Products Engineer who worked on the Rochester H and HV projects in the day.... be sure the float spring is agjusted properly. With the float hanging down, the spring should hold the float assembly nearly weightless. Too much float drop-weight can cause Venturi drip especially with modern gas and all it's additives. The fuel float valve quality can also play into this if the floats are too heavy. Fuel pressure will open the valves. However heavy floats will have more of a problem closing them.

For 40 years this tip Works for me!

I've used 1-1/4 and 1-1/2 with no problems.

When rebuilding mine I went with what Clark's instructions stated. I figured they have found in the past that these levels work better than the Manual (maybe the difference with modern gas?). No problems so far, but it's only been a week.

I used Clark;s numbers when I rebuilt mine. Had a bad hot start problem so I lowered the float level some (and installed double insulators). Starts fine now.
