Hey Guys,
I have an old Masport 460 which I really like to mow with. The big propeller style blade cuts well. The only problem is, the motor is blowing lots of blue smoke and using lots of oil.

I have decided to swap the engine out with another 3.5 hp briggs.

My question is quite a simple one, and I'm sure it will be an easy answer for someone.

Any tips on getting the blade adaptor off the bottom of the crankshaft to swap onto the other motor? I'm pretty sure it just slots on and has a keyway to stop it moving. It's pretty tight and I'm out of ideas.

Any suggestions greatly appreciated.
