installed a new vro pump still have to depress the key prime to go into gear get her to run at 2000 rpm tied to the dock. for a while . then she stalls could it be low compression? SHE seems to suck oil because the level goes down. but why isnt she sucking gas properly? I have gone over this engine with a fine tooth comb??? Any suggestions or ideas would be greatly appreciated!!!!!!!!!!!!!! thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
