    When I got back and put it away I saw gas on the ground. It may be only when the engine is off now like before I started. It is freezing today / yesterday was 68 degrees. So that will be all for today.

    I will pick it back up again in a few days / hopefully it will be warmer then. I will pull the carbs again and do a little better job of cleaning. I plan to clean out the low speed jet with an e-string (I have one ready) / I will also polish the float valve seat and check the tubes for leaks to stop the pissing fuel out of the overflow tubes.

    A few questions:

    1. Do I just polish the seat? Do I do anything to the float valve rubber tip. When I lapped the valves on my lawn mower I put compound on the valve and spun it with the suction cup rod to match the valve to the seat.

    2. Should the floats / float valve be springy once installed? I see videos with a different version where there is a spring in the assembly / I have a 81 CB750K which has no spring or adjustment as far as I can tell.

    3. Where would you buy replacement O-ring clamps for tor the carburetor engine side boots. The ones I have don't seem to get tight enough and the carbs seem to slip out if moved a little. I see that Randak's has them but they are very expensive. I replaced the air box side boots / I ordered through Honda parts.

    I am learning a lot along the way.

    Thank you for your help. You guys are great!!!

    Check out Randakk Cycle Shack. He is a 70s Honda Motorcycle restorer and supplies hard to find parts. I have used him a few times for my 1978 and 1979 GL1000s

    As you can see from the pic's I like my old Honda.
