Nice new fittings

Operation Engine Rig

I have two options 

1. Put the rebuilt engine in the frame run for 500 miles then take the engine out to torque the head down then put it back in. 

2. Build a rig to run the engine on then torque the head and the put  in the frame minimising the damage to the new powder coating on the frame.

Option 2 has the added ability to balance the carbs and get the tappet gap spot on with no awkward angles to work the feeler gauge.
