1 cylinder is not getting much fuel. I have swapped carbs and the issue follows the carb. Went through the carbs once but issue persists.

Will go through that carb again.

which passage is the idle circuit / jet?

Also, These carbs cross feed the cylinders, correct? IE, starboard top cylinder is fed by port top carb?

Thanks anyone for clarifying!
 
See my other reply to your previous post.... about the high speed jet! Fuel has to flow through that jet before it can gain access to any other fuel passageway.
 
Wait I'm confused by 90hp versus 90 degree.


are you saying my 60 degree looper, 90hp does not cross feed? I.e. Port top carb feeds port top cylinder?

thank you for your help!
