Maybe in sunny South London, but here in the States it might not merit a second glance! :)

My thoughts exactly, where does the right to bear arms end? Nukes?

Hey! We're actually pretty fussy about nukes over here. We require a permit, background check and 90-day waiting period. Now back to our topic: is 150 psi acceptable compression on a 1275?

No - not really - it's very much on the LOW side of acceptability.......

And that must be checked warm, throttle open, and all plugs out, correct?

I'm sure this has been answered elsewhere, but what would constitute an acceptable figure for a 1275? Thanks!

Whoa...then mine is well shy of the mark! Thanks for that info. I have a Midget 1275...does that make much difference?
