thanks for the help, i ended up having to loosen the exhaust manifold b/c it couldn't just drop straight down, on mine there'* a sheet metal pan thing welded across the whole bottom. and now...my problem is that it doesn't start, i think it might be that it'* got half a tank of gas that'* at least 10 mos. old, and i'll fill it w/ new stuff tomorrow, but if that doesn't work then i'll check the plugs. when i squirt some ether into the intake it starts right up and runs fine. do u know of anything else that might cause it not to start up?
