Ok, took the intake off to redo the intake gaskets. Put everything back together, hook everything up, double check all my connections, drop in the dizzy...well, it doesnt go in the same way I took it out....
Ok, so I rotate it clockwise a little, and it slides into the spot...
I figure that maybe I was off a little, so I hook it all up, go to start it...nothing.
Alright...somethings not right here...why doesnt it want to fire up?
Ok, so maybe the dizzy is 180* off. Take it out, rotate it, drop it down, slides right in, hook it up, go to start.....again, nothing only this time with a loud bang....dunno what it was, didnt see fire or smoke.
Any ideas? It just tries and tries, but doesnt start.
