But only so the mark on the arm lines up with mark on case DO NOT wind all way to end(dont ask which end, i cant remember) or the internal cam can jump the arm which needs casing removal

Hi all,
So have improved the clutch position sufficiently for now that it doesn't stall.
Went on a bit of trial and error on to find the source of the ticking noise but no luck so far.Used screwdriver to try and pinpoint but no luck.
1. Checked exhaust headers and tightened the nuts - few of the could take almost a full turn but no success.
2. Readjusted the cam chain tensioner - did move it half a turn when running to see if went away in a different position.
3.Removed a couple of the tappet covers and nothing obvious. Will double check clearances next weekend.
4. Disconnect spark plugs one at a time - ticking doesn't go if a cylinder is not firing.
I did note that running only 3&4 will ifle but only 1&2 it needs a bit of throttle? Carb synch issue? I vac synced them last week though.
Do the tappets have lateral as well axial clearance? I

Very long shot but based on my recent experience could it be the kickstart ratchet touching the pinion? This has been confused with primary chain noise in some other threads.

I'll add it to the list. Given the fact that I just put the kickstart assembly together through the sump access its totally feasible.
I do have a spare set of exhaust washers from the vesra kit as I used the ones that came with the delkevic exhaust. I'll try and replace the washers and reseat 5h3 exhaust next weekend.

After taking a screwdriver to diagnose the noise, I decided to re-di the tappet clearances and it's now 10 times better. Still a slight tick but I don't have a reference for a "good sounding engine" so will keep it as is.
