Rule Of Thumb Always Pull The Exhaust And Ck The Condition Of The Cylinder And Piston Always !!!!!! This Shows So Much It Makes Or Breaks

I wouldn't go any lower then 100!!! but 90 is the lowest....., around 90 it'll start, after alot of effort...

50psi like others have said, never will run...
Be best to take the exhaust off and turn the engine so the piston is at the bottom, and look at the bore.... should be (in a worn engine that runs) nice and slick... no vertical scars should be seen.

Could have formed a air leak, and run it lean or he wanted to play with the air/fuel mix screws and ran it lean that way.
