Ok i noticed my base gaskets were leaking. when i first got it running i had 170 psi and no leaky gasket. now i got ruffly 155psi. it will only start up and stay running for a few seconds then it fowls the plug. would leaky base gaskets cause this?

another thing i argued with my father about is spark plugs. once there fouled there garbage right? he seems to think i can throw them in my blast cabinet and clean them off.

your spark plugs can be cleaned in a blaster cabinet.. this used to be the way it was done back in the day. For some reason you don't see it much anymore and for a couple bucks people just consider the spark plug disposable. In your case I'm sure the plug is fine as long as your clean it properly.

As far as the leak goes... If you've lost pressure you have an issue. Was the 170psi before you fixed the leaky cylinder base gaskets? Or was the leak discovered after a rebuild>?? Give us a little more details and history and we'll try to help.

i'd do a leak down test as mentioned. it'll help you to find every leak. including the seals. when doing the leak down. you should remove the stator cover to check that seal and its not a bad idea to remove the clutch side cover. with you suddenly fouling plugs there is a chance that the clutch side is leaking.

More them likely you are just too fat if you are fouling plugs, but you could be sucking oil through the cases?? what carb and what main? usually if you have an air leak the motor will run lean, so you over jet the motor to compensate...... but losing compression like that would not be becasue of an air leak. you have something else going on, now maybe you have a seizure problem becasue of an air leak?? bottom line you need to find out why you have lost compression. just a thought ;)

oil could leak into the crankcase from either a bad center case gasket or a bad clutch side crank seal. from my experience it'll smoke like a bitch if it's sucking oil in from the tranny
