Plug lead ordering & compression

Not on any of my cars, it isn't - bottom right, nearest the rad, arm @ 4 or 5 o'clock

Ditto.

I think it is possible to assemble the distributor with the offset key drive 180 degrees out, which would give the firing positions you have, Moggy Tech.

I seem to recall a thread on here where somebody had bought a reconditioned distributor like that, and couldn't work out why their engine wouldn't run with the leads in the old "correct" positions.

mmmmmmm me thinks maybe thatys why my car isn't running right!!!!!!!!
see mechanics form rough running....

No - doesn't matter which one is #1 - as long as it's when that cylinder is at tdc and valves closed - others then follow 1342.

Hang on is this a side valve or OHV engine??
