Fixed Timing

#1

Post by weverat1 » Thu Jul 04, 2019 4:57 am

My brother gave me a 42 WLA ! It is a rolling basket case, but I am all over it, and will get it running shortly.

It has a magneto of which I am probably going to run in a fixed position with no retard for starting.

Do I need to back the timing down a bit in order to start with out backfire ?

I see the full advance timing spec is .280 btdc, should I bring it back to about .200 ? or what do you guy,s suggest ?

Thank You

Do not try to reinvent the wheel, set the timing according to the flywheel mark, lock it down and forget it. It needs to be set where it runs best, not some random spot. And what are those numbers you are quoting and where did you come up with them?

And go to the new member section and do an introduction, it will serve you well. Also see the Knowledge base and Documents sections as most questions you may have are already answered there.

Ok, so if I set the timing at 9/32, or with the flywheel mark, will it kick back ?

Remind me: for which engine does Harley-Davidson provide and recommend fixed ignition timing?
Take as long as you need for an answer.

Sorry, I should have said "sold for road use".
Ever see a magneto Sportster? Even a diagram? List of parts? Owner's manual?
Do that, then delete your post.

Every Sportster XLCH sold for Road Use prior to 1965 used a fixed position, non retardable magneto. There are many thousands still in use to this day. I fail to see your point or your argument.

Pardon for the butt-in,

Robbie, Is is possible to get a copy of the other pages of the suppliment concerning the magneto installation information.

It would be of help on my WL-KH mishmash engine.

Thanks.

George

Not if you kick it fast enough.

The secret with all mag fired bikes is to kick as though they owe you money, ran over your dog, and slept with your wife.

Well, that, and a well tuned bike.
