Last Sunday I thought I would clean up the SU filters as they looked
dirty. After removing the filters I noticed what felt like wet gas
right at the intake of the front SU. When I lifting the piston on
that carburetor I noticed a slight dribble of gas come out of the
disconnected (now reconnected) vacuum advance tube to the
distributor. When I put the piston down it stopped & when I lifted
it again the flow restarted. The next day when I rechecked there was
no dampness nor dribble out the disconnected vacuum tube.
Does this sound like float on the front SU is set too high??? I have
not seen any flow out of the overflow tube.
Given that I have not rebuilt SUs in about 20 years, I cannot
remember if I can adjust that float with the carburetor mounted on
the engine (just take the top off of the fuel bowel), or if I need to
completely remove the entire carburetor to do the job?
Any advice would be appreciated. With the long weekend coming up I
thought it would be a good time for a little adjusting....
