dead on road update

Barry, My previous post about the carb's float setting involves removing the carb & rotating the carb body about 90 degrees so that the float hangs down like a pendulum.  The carb is rotated until the float tang just barely contacts the pin on the float needle & then the float height is checked. If you're very careful, you can check & adjust the float with the carb mounted in its normal upright position.  The problem is that many float needles have a spring loaded pin that contacts the tang on the floats.  Sometimes the spring is very weak & it's easy to get an improper reading because the pin is partially depressed. To change the float level, the tang is bent (very little & very carefully) to change the float height.  This trial & error routine is repeated until the floats are properly set.  You can use a small flat blade screw driver to bend the tang.  Double check that both floats are the same height when your finished.

As an aside, sometimes a float will leak & hold gas inside.  In this case you can have perfectly adjusted floats but the added weight will cause a rich running condition or gas overflow from to high a float level while running.

You may be able to service the coasting enrichener by following Kurt's method of disconnecting cables & rotating the carb (after removing the gas tank).

I believe that the resistor type spark plugs are to help reduce electrical interference for radios.  You should not notice any difference in performance if you use the proper heat range spark plug, resistor type or not.  Correct me if I'm wrong.

Proffesor,

I'm not following the float setting info you provided.  I take it this method is done with the carb off, bowl off and the carb in the upright position...

Measurement is done from float bottom to the float bowl mateing surface.  How does the tang on the float come into play here? How is it adjusted if it is out of tolerance?

Maybe I'll just have to do it to see it next time I have the carb off.  I think I am going to look closer at the coasting enricher on the left side of the carb to see if all is well there.  I don't recalling seeing an O-ring but I could be mistaken.  Is this easy to get on and off with the carb on the bike?

Thanks for all you thoughts, advise and help!  That goes to everybody!
