ok i just got all my cylinders pistons rings ect... back.... ok i had a lean problem on one cylinder.... so there is only 1 line going to each carb and the lines are clear... it looks green (oil mix) in one line and the other line looks like just fuel (clear).... is that block where the fuel line and oil line goes plugged.... does it mix right there... i did hold wot and run the oil pump with a drill and got oil to the block..... any help would be great... i just need to get this figured out be for i slam the motor back in... thanks ty

The oil and gas gets mixed IN the fuel pump, thinking you have a blockage
open the f/p up and have a look.

well.... i took it all apart and all look well so i pulled the lines from the carbs and blew back in to the pump... (gas in the eye hurts) lol but how much oil should come in to the fuel pump when oil pump is ran from a drill (fast speed on drill) it was going in just very little.... i think it should be ok now.... i think it was a lean problem bcause the one piston was crome and the other was brown
is that what the problem was???
