Having gained the confidence to grind values I have started to de-coke and
grind the valves on a JAP2A engine. The manual says "remove the flywheel
using the special extractor tool". Can I do this without this tool please ?
In addition how do I time the engine once I remove the magneto - are there

The JAP 2A manual I have describes undoing the bolt to remove the starter
pulley, then drawing off the flywheel with a puller. If no puller is
available the manual states that the flywheel should be "grasped firmly and
then whilst attempting to pull it off, tapping the end of the crankshaft
with a mallet or lead hammer"
When re-timing the engine and no timing marks are visible: With the head
removed and the flywheel loosely fitted (so it can spin round without
turning the engine over), set the piston so it is 3/16" before TDC and
rotate the flywheel until the contact breaker points are just starting to
open. The flywheel should then be tightened and hopefully you will have a
spark 3/16" BTDC.
