Re: 318 ignition system

If you are using the flywheel end for timing (recommended) the center of the arrow is TDC. The required advance is on either side of the arrow, one side for normal and the other for reverse rotation. One problem I've seen is that the spark advance mechanism does not return to the idle position do to...

Re: Marinette name plate

And if all fails, you could get someone to cut you a decal. All you need is a good photo of the name plate for a graphics shop to produce what you need.

Re: 318 ignition system

Re: 318 ignition system

Are you sure the secondaries are opening? If the choke is not opening fully it prevents the secondary barrels from opening. With the motor fully warmed up, shut it down, pull the flame arrestor and see if the secondaries open at full throttle. If not that's the problem. Readjustment of the linkage w...

That'll do it! Had an impeller grenade on me as well and plug up the starboard side of the system.

Re: 318/392 Stroker Motors

Unless some kinda metal bug ate your impeller, I doubt if the circulating pump is the problem. (Their seals leak, that's all.)

Re: LM 318 140 thermosts

Temp will shoot up after a motor, that has been working hard, suddenly shuts off.

A case in point: Running my old Merc OB the other day when a ground strap fell off. (Stupid mechanic!) Motor was at full song when that happened, and the temp shot up to 240 ' F. Normally runs about 120.
