Did a 200 mile shake down since the strip down & rebuild the checked the torque of everything & all is ok there. Just one niggle, think i'll need to go up a couple more sizes on the main jet as it seems to run better with a tiny bit of choke even once it's warmed up.
Might also need to get some ear plugs or wrap some deadening around the baffles as those cocktail shakers are obtrusively loud.
