I'm brand new to the board this evening and hoping you folks can help.
Just so you know I'm not a complete idiot , I have been working on pre 80's V8 motors for most of my life. (I'm 64)
Now, with that being said, I'm sure this is going to be one of those "You stupid idiot" moments when you tell me what I did wrong.
I rebuilt the Kawasaki FD620 in a friends 6x4 Gator, It fired up and ran but it was spitting fuel out the carb (a lot of fuel)
I pulled the engine back out assuming I must have screwed up the cam timing, I didn't, the timing marks were fine.
I manually ran it through its cycle(s) and deduced that I could possibly be 180 degrees off.
I turned the crank 1 full turn which brought the mark on the crank gear and the cam gear to the 12 o'clock positions, I then pulled the cam out and rotated it 180 degrees to it's 6 o'clock position which then realigned the marks. I put it all back together installed it in the cart and its still doing the same darn thing!
Just so you know what I'm looking at... the mark on the cam gear is about a 1/8" to 3/16" dia hole and the mark on the crank is a punch mark. I do not see any other marks on either gear. And of course the service manual just says "Line up the marks"
When I run it through it's 4 "strokes" with a wood dowel in the spark plug hole, I can see that the intake valve is opening to soon.
Either the marks aren't right or I'm doing something totally wrong.
Any help with this will be greatly appreciated, and please be gentle. "You [email protected]#$#%$ idiot is totaly acceptable" I can take it!
