Thank you all for the kind words!
JAWS: Well, i'm broke now and my first plan is to ride the wheels off of it next season (it passed inspection last monday, now i'm trying to get it registered), but other than that i know what you mean... my fingers are already itchy again
But first i have to get it running better than it is now. I'm suspecting the carb to be the culprit, but i don't know for sure yet...
Just to make sure i did the timing right, i'll show some pics of the magneto.
We modified the adapter plate and made an adjustable bedstop.
The plate came with the magneto and i was told it was for a sportster,
but i don't really know how one should originally put the magneto on it and
still be able to move it? I think there might be some parts missing, but anyway, this is how we did:
I defined the full retard point more or less by trial and error by turning the magneto as far back as possible with the engine running without killing it or having backfires. then i double checked with the mark on the flywheel, which should be 35°BTC i was told. so with a 30° adjustment angle on the mag i should end up with 5°BTC at full retard.
I now turned the crank until i saw the marking on the flywheel (35° BTC). I thought i'd have to insert the mag at full spark advance and time it there, since the flywheel mark is the only precise mark i have. Please correct me if i'm wrong!
I lifted the pushrod covers on the front cyl and made sure both valves were fully closed and piston is in the ingnition stroke.
Now insert the mag into the block:
Note the kill switch built from a nail file i had lying around. Works great.
Now i kept lifting the magneto, turning the shaft and reinserting it until i had the smaller one of the 2 lobes, which belongs to the front cyl, just short before opening the points, at full advance.
Afterwards i adjusted the points, closed everything and fired up.
Is that correct so far?
What points gap are you running on your magnetos?
This one is a Joe Hunt, cast housing i think?
Are there better methods to do this? I feel like it's pretty rough somehow,
and i do this for the first time, so i'd be glad for advice.
I checked the magneto threads but didn't find a step-by step timing walkthrough.
