Martin 40 hard starter

[78bluestreak]

So One Martin 40 starts on 2 pulls, the other nothing.
I have checked spark, good both cylinders
I have checked condensers, both test fine
points polished and gaped.
fresh fuel, oil ratio correct.
cleaned carburetor, floats not sticking.
Primer is working.

I was told that this engine was a hard starter in 1955, it’s still true and accurate.
suggestions on next step to getting results on two pulls?

I once had a Martin and it started very well. Agree with checking the O rings on the valves.

Make sure the poppet valves completely close. Then lap them in.

I’ve got many years as a youth and young adult with a martin 40. Don’t know of a primer on one but there is a choke…ya need to find out if it is a lean or rich starter first. Make sure choke closes fully.

Mine ran so much better after I put on a diaphragm carb off a techumsah 2 stroke 5hp…way back in 1973 or so. Vertical throttle shaft made it easy.

this model has the flex line to prime the engine. I have the front cowl off so I can see the primer move and smell gas. the second unit I spoke of has a different carburetor set-up for the primer. straight shaft, no flex line. i am thinking the condensers may be an issue in getting this unit started. My method of testing (based on recent article in Outboarder) magazine was lacking the proof needed.

thanks I will look at this also..sounds like this issue may be an on-going and long issue for the grandfather. could be how he was able to buy it from the marina where he rented a boat.

So Friday this week I got back to work on the motor. 40 minutes of pulling produced a start and fair run. so I went form rebuilding a leaking carberator to thinking that was the magic bullet. next day went out pulled three times, almost turned over . 20 minutes later I broke the recoil starter pawl that engages the flywheel.
so is this motor effected electronically – or mechanically?
I’ll pull the coils and condensers and upgrade.
as to the recoil any one have experience with repairing the pawls?
It appears I will have to contend with the rewind spring.
