The PM Research 'tap' has been fantastic to be able to stop fuel just running everywhere.
And that new system the Chinese are using to fix the flywheels on is just a brilliant solution I hope it filters down to all engines petrol and steam
coming out of China. Its so simple, just one bolt will hold the flywheel on tightly and there's no danged allen/grub screw at the back that was almost
impossible to get to and so easy to strip trying to get it tight enough to firmly hold the flywheel on.
