haven't come to far from last posts i tore the carb apart and checked every little thing to sterlings specs.

today i tore off the manifold just to start my "whats thought to be vacuum issues" elimination from the farthest possible point on the motor heres some pics

i am also about to be on my 3rd nikki 2nd manifold and 2nd spacer with this dam thing... i wanted to know about freeze plugging my antifreeze ports anyone know of a cheap plug?

also if there is anything wrong with my setup in the pics let me know, and is it bad to not run a check valve on the oil breather cuz i have a vac line straight to the spacer..

 

20mm plugs work good.
