Hi I'm new to this site. Does anyone know what pressure I should expect from hand cranking a P5. I'm getting 75 PSI.
I tinkered with the engine for half a day and it runs beautifully even with that strange carby.

Stuart reckon on a ~ a 85 PSI compression pressure when cranked @ ~ 180 rpm.

Hope that helps,

H.

Hi Hugo
Thanks that means I'm in the ball park. As I reckon I would have been cranking at half that. From now on it should be fun I just have to make a few little bits.
