thanks for all your replies. i think i might have additional probs with air leaking past carb.
when the motor is turned with my finger instead of plug i can feel great compression and alternately considerable suction.if i put my finger on the carb 'spigot' (on the reed valve block where you attach carb) i feel almost no suction when motor is turned. it can just move a piece of tissue paper.
how much suction should be at the spigot?
also i pulled out reed valve. the thin metal was not fully closed. at atmosphereic pressure should the reed valve be fully shut or is it acceptable to have a little curl at the end?
