Well, i'm just about finished putting the powerhead back togeather!!! The last step is trying to figure out what position these damn bleed line check valves go! I know where they go, one is on the top, and one is on the bottom of the block, but which was is the block suppose to bleed? Pressure from the bottom is bled to to the top? or opposite? Block bleeds from the top to the bottom?
Hope you guys can help! Thanks!

Hi,

They are ment to pump the unburnt oil from the bottom to the top and burn it after it does a little lubing of the top crank bearing.

Thanks Corm!
So then if its ment to pump from the bottom up, and I install a new fuel/oil hose and its bone dry. Should I add a little bit of oil to the hose before I install it so it has some oil once the powerhead fires up for the first time?
Thanks

That is unnecessary. Most of the upper main bearing lube oil comes from the air/fuel mix from the top carb.
