Hi guys.. what a way to start my new job today as a mechanic at a landscaping company... There is an edge trimmer there.. I can't remember the name of it for the life of me.. but anyway it has a Kawasaki FC420V 14HP motor on it. What happened (from what I was told) The edger is front heavy because of the motor and it was tipped forward and laid like that for a few hours.. I was told that this 'filled' the cylinder with oil or something.. The oil wreaked of gas.. They said the fix for it was to drain the oil out and make sure it's all ok and it should start and run fine then. Well I drained oil.. replaced filter.. refilled the crankcase.. go to start it.. nothing.. got a few carb back fires saw a spark jump out of the carb a few times but that was it... After that you just pull and pull and pull nothing.. SO I put a compression tester on and yanked.. Needle would jump and then drop back to zero.. No compression.. no wonder it won't start! So I rip the valve cover off and go to town.. notice that the exhaust valve for some reason is being pushed open slightly when the piston comes up for compression.. letting the compression out.. wtf... So I set the piston to TDC on the compression stroke.. Guestimate a good valve clearance (since I don't have any factory specs on it and no Kawasaki spec book for this motor) and I put it all back together.. leave the valve cover off though.. Yank the cord and UGGGGHHHH.. cable snaps out of my hand.. So I try it again this time slower.. everytime it comes up for compression.. you CANNOT pull the cord.. just won't budge! For some damn reason the camshaft was pushing the pushrod out and making the exhaust valve open slightly .. which I already went over... EVEN AFTER I set the valve clearance! I'm lost and confused on this one.. with out ripping the motor apart.. I'd like to impress the boss.. so if anyone has any clue as to WHAT THE HELL is going on I'd really appreciate some help! Also, I'm going to try another google search to find engine specifications but if anyone has them bookmarked or something please post the link, thanks!
