1994 Johnson Venom Fuel problem

I just bought a 1994 johnson venom Model #J225STLERK. I am having a problem keeping the thing running. I seems like a fuel problem. I went trough the carburators and everything seemed to be fine. All the jets were clean and there wasnt any trash in the bowls. The primer bulb is sucking gas but gets hard to the point where it cant be squeezed. The VRO is disconnected and the wires to the fuel pump are unplugged. Im trying to figure out if the fuel pump is bad but i dont know how to trouble shoot it. I dont know how the pump works and is it supposed to be getting some sort of power? Anyway im starting the motor and it starts easy right away after priming but then it doesnt stay running more than about a min and then kills. If i try to give it throttle it just bogs it down and kills it. I also checked to compression and 5 cylinders were around 100 PSI and the top left cylinder was 130 PSI. Not understanding why this was like this i decided to pop the heads and inspect. I found that the high psi cylinder was missing the exaust rilief hole that is drilled at the end of the cylinder wall. I dont know if it came from the factory this way or if the cylinder was re sleeved and the hole was not drilled. Evinrude said that motor was not resleevable??? wich doesnt seem right to me either. SO i need to figure out this fuel problem and if running this motor with 5 cylinders at 100 psi and one at 130 psi will hurt it. http://xs-s.com/zf/images/smile/emthdown.gif http://xs-s.com/zf/images/smile/emthup.gif Thanks for the Help!!!

Probably needs a bit more troubleshootin...

What about performing a spark test, set an adjustable gap tester to 7/16th inch gap and look for bright blue spark. Auto part store sells the tester for $12.

Try hitting the choke when putting it into gear.

pre mix sum gas in a jug. pull your fuel line and put it in the jug. pump the bulb and try to run it. if it dies like it has been try pumping the bulb as it is starting to die. if it keeps running i would say your vro is bad. you can pull the hose on the top of it and see if it is pumping also. i have been there this year.

it gets no power. those wires are for the oil injection side. its vacume powered

i figured out the problem. It was a bad fuel pump. tahnks for the help.
