Hulloh there just in got some bother with Paypal(again)
Anyhow I see somebody with a MG problem who hasn’t:)
Any how from what I am reading seems fuel in to manifold,,,,possible ctrics
Good bright spark at the plug? better checked at low light, amazing the difference
The thing is it seems the chain has been split so and the movement disturbed so everything needs to be reset to hit where all should
C/Shaft and piston straight forward set it at TDC as is said keyway 12.00 though easier if the piston is brought up to DC and stopped I will stop momentarily to change direction, a hand on the piston will tell when it is there ,,,,,mibi with some practice??
Then the valve timing needs to be set at both closed position with the overlap sequence to match TDC Firing sequence, and not “on the rock”.
The magneto or more precisely the Magneto drive “D” dog needs to be set so that when the magneto impulse clickS it clicks over TDC.
All that done without chain connection to the cogs.
It is a bit fiddly the ag needs to be set just as the impulse fires totally dependent on the position of he drive,exactly into the Magnetodrive with the coupling timed with the rest of the sequence Acuracy is essential as leaway a tooth either way will affect the fine tunning or/ and starting or running Best thing is to accurately mark everything to a datum someplace perminant as setting up the connecting back up bit can be problematic Don’t try that with themag in place youll be fighting an impulse
When every thing sorted double check the sequence the piston at TDC both valves closed and impulse just fired
PS It is east to get it wrong refitting the chain sometime it can be a tooth out on the timming
Works for me ……..Eventually good luck and patience
