Re: ENGINE WILL NOT START CONTINUED

[wmmulvey]

THANKS FOR ALL YOUR HELP


Engine running great last 4 yrs. plus.

Replaced rotor, points, condensor, wires, and plugs as routine spring maint.

Did not touch timing.

Last run of A-4 was on 6/9/11 for an hour or so.

Week later was the start of the NO START problem.


At that time I did all the ignition checks and replaced dist. cap and coil.

Compression good on all fours.

TDC on the compression cycle. Rotor facing 9 o'clock. Rotor on the dist. (left it off once a long time ago

) LOL

#1 SP wire from flywheel end at 9 o'clock
#2 at 12 o'lock
#4 at 3 o'clock
#3 at 6 o'clock

Gas good

Carb float bowl OK.

I do not think the carb jet is fouled but will check this out in the next round.

Next step maybe valve timing.

I went on Moyer Marine and I did not see any parts labeled VALVE TIMING GEAR.

In the service manual under the troubleshooting section under ENGINE WILL NOT START (POOR COMPRESSION AND OTHER CAUSES) it suggests valve problems amoung other things.

Has anyone done a valve timing? How difficult is that?

Does the The Moyer Marine Service and Overhaul Manual show the complete breakdown and rebuild of the A-4.
