Carburetor Tuning

[Ivin <wsurfer1@mindspring.com>]

Hi All-

I brought my Roadster over to a friends shop to have my carburetors 
checked out cause I cannot get them to run lean at idle.  He has a 
Roadster and a few "Zs" and if fairly good at tuning his carbs on his 
Zs.  Anyway, he took a look at them and is puzzled by the type of 
needles used in them.  I already forgot what size he said they were.   
Does anyone no what the proper size needle should be for a 66 SPL-311 
1600-cc Roadster?   Also, any suggestions on what to do to get them to 
run leaner.

Thanks

Ivin
