Ayuh,... It takes Fuel, Fire,+ Compression, All at the Right Time, for a motor to Run....

The shift switch should be Centered All the time, except when shifting From forward or reverse To neutral...

ok i will check the compression how much psi is good,and let me get this straight the switch only works when i shift to forward or reverse. ok but as soon as i have it in gear do the switch pivot back to the center spring loaded while im still in gear.

Nope,... Only when coming OUT of gear,+ Only IN the water....
At ALL other times, it's centered....

150psi is a pretty Good #....
Less than 100psi is a Junk motor...

Re: still wont start

so maybe that my problem when i have in forward or reverse the switch is compressed. if you say that allways in the center the roller in the v area my switch is cutting my ignition. because my motor wont start and switch is not in the center. but how if my switch is in the center in neutral.any way im confuse so the switch cut the engine half a second and return back to the center while im in gear correct.
