Message: <blockquote data-quote="kilohertz" data-source="post: 94359" data-attributes="member: 6974">I put in the new starter, completely disconnected all electrical from the machine, centered the sticks, put in fresh fuel, replaced the missing hydraulic hose, topped up the hydraulic resevoir...and got ready to fire it.I simply connected 12v to the IP solenoid, and cranked it with a hot wire, nothing else connected. I just wanted to see if it would run....it didn't. Made sure the lines were purged of air, cracked the injector lines and let the bubbles clear while cranking, tighetend them down and still nothing. Finally decided on a little breath of ether to see if I had compression and sure enough she coughed, and a few more cranks and away she went...ran nice for about 2 seconds then immediately took off full bore, wide open run away it's gonna explode type fast...that was scary...thank the good Lord I had the forsight to disconnect the air intake pipe at the manifold and I had a tennis ball ready to stuff in it, which I did and it shut right down. Even pulling the IP power wire off wouldn't stop it. After I cought my breath, I started it again, with tennis ball in hand, this time when she caught and showed signs of takeoff, I used the tennis backk to modulate the input air and was able to control the RPM, crude, but it worked the engine ran just fine, no knocks or bad noises, just LOTS of black smoke. Let it idle for about a minute hoping it might clear itself but it didn't...it still wanted to run away if I removed the tennis ball.  If I cut the power to the IP while it was running mid speed, say 1800 RPM or so, the engine would quit, if it was running at high RPM, around 3000, removing the power to the IP wouldn't kill the engine, the tennus ball was required to block the air to shut it down.So, I have an excess fuel problem....anyone know if there is a common failure mode in the IP? Seals, govenor, anything else? Don't know where else the fuel would be coming from.Help! Your thoughts?cheers</blockquote>
