compression sounds slightly low to me but depends how you checked it .

you need to open throttle fully and kick engine over a few times so it gives the the compression gauge a chance to get an average reading .
usually the compression gauge will creep up each time you kick engine over , to a point it wont go any higher .

my model 30 is between 135-140psi .
