Thanks for that Ade,the engine is not seizing up as I thought as when it stops it will still turn.Have tried to remove both flywheels but they won't budge so
gear pullers have been ordered can only assume the loose flywheels have created a burr on the crank and yes I will be gentle.Also have removed the governor weights and arms and the grub screws holding the flywheels are loose so new ones ordered could be the problem hopefully !!!.
Cheers Trevor.
