1938 S Pilot Jet size and Rocker Arm Bearing Oiler

[guzz...@gmail.com]

I have a size 50 Pilot jet in my 1938 S and my Idle Mixture screw is all the way in. It still needs to be choked to idle w/o backfiring through the carb. Off idle I need to take the choke off to run it. It seems to want a larger Pilot jet but that"s the largest I could find.This is based on turning the mixture screw in richens the mixture. This is where it runs best.

Anyone have a solution to the grease pot leaking around the threads while turning it in to oil the exhaust rocker arm bearing.

Thanks Bill Doll

Could be a worn slide causing it to be lean. 
I know the old Harleys you screw in the grease pots to force in the grease. Is it the same on the Guzzis or do you screw them insight and they drip oil into the rocker shafts?

My 1945 Airone behaves similarly. It does have a worn slide!
