And seeing if that makes any difference.
It sounds like the kickstarter is not meshed or located correctly.
Let me find the Ajay booklet to refresh the grey cells, if someone doesn't chime in sooner.

On a twin, you'd just swap the plug leads over.
But 4 stroke singles don't work like that.

Aye, if all ye backlashes accumulate, then you may be in no mans land....
Lightly tapping the sprocket onto its taper is highly recommended,
or it may slip or move while you are tightening up the nut.

I usually start my bikes on just a little retard (rather than half) but all bikes are different and yours might need more retard.

« Last post by dynamic on July 22, 2025, 11:59:30 AM »I was carefull not to disturb crank or timing/cam sprockets ,I did wipe the mag shaft before replacing the sprocket maybe I disturbed the timing then ,
I have set the piston full advance (lever slack cable) at TDC then back 7/16 BTDC watching for the points to just start opening before replacing mag sprocket ,
I am getting a bang back through the carb ,I have the advance /retard at mid way point
if anyone could help me to re time motor I would be very gratefull
