Question about spark, I’ve set points so many times are it seems I just don’t get as great of spark out of one cylinder as the other cylinder.. is it normal to have one not as good as the other? Coils/condensers/wires all meter out to exactly the same but seems too cylinder is just weaker and can find out why.. thought it was gap in points put they’re exactly the same.

yes below is my next headache stripped out top spark hole. Had everything in/out so many times and over looked the out come of heat on aluminum. Unfortunate but seems to be a lot of lessons.

It sheared last trip out on water long after that was mentioned and I believe it was timing

I suspect that your woodruff key sheered off because you failed to torque the flywheel down to 65 foot pounds of torque.



Did you catch that it was 'well greased', too?

After reading that the cracked flywheel seems less likely.

This should clear up your questions regarding timing your 1956 30 HP motor.

Correct on screws I believe I’ve got that it was what to line it up on but your picture showed that. Made woodruff key twice think I’ve failed it.
I guess a day away wasn’t enough..

These are the two screws that hold the butterfly cam.

Vintin thx and np I get everyone has their own stuff to do appreciate the time. So that adjustment screw is tight but doable and that’s what I thought Ray was referring too in earlier question to me. So I lined up cam follower to brass cam to just crack throttle as it hits mark.. it was out considerably (3/4”). And thought I had it until you mentioned the index cast on crank case.. 

so now I will find index cast mark, line up brass cam too it.. then see where cam follower is set. If cam follower needs to be moved I do think I can adjust on throttle linkage set screw.. but don’t quote me on that.

then I’m going to try make woodruff key to fit as parts store was useful as they always are to me and had nothing.

I’ll update you after my findings. Don’t feel obligated but I will keep asking questions.

 




I don't mind answering questions.

I only brought up Boatboy to taunt him into the thread. I've not worked on a motor that is before 1957 and I know that John has.  He can get them running so that they don't even smoke!

I had a slight change of plans as it is drizzling outside at the moment.
