I have an O-360-A1 and see about 1.5GPH spread between 1/2 and 3/4 (3/4 run richer). 1/2 are very close, and 3/4 are very close. This is at about 2300rpm. If I try to run WOT it gets much worse and the engine is too rough to run lean.
I attempted to correct this with an airflow straightener on the intake to the carburetor (per another thread). This worked very well at 2200rpm, but made the spread worse at higher rpm's.
I am considering trying to add a cross-flow pipe between the 1&3 and 2&4 intake pipes. Has anyone tried this, or have an opinion? Does anyone have a set of used intake pipes they would like to sell?
