    A good idea to see if the engine will turn over by hand first. Look at the rear of the engine, shaft (PTO) going to the jet pump. It'll probably have a cover over it. Unbolt the cover, remove the...

    There are small parts inside the switch, springs and plates that easily fall out. Make sure nothing's missing.

    The outer seal should have pegs and a single lip on the inside where you grease. This goes on second with the pegs and spring facing out.

    Some seals have four pegs, some have more, but they...

    Pegs face out. Have a look at the seals. The one without pegs should be double lipped inside where it sits on the crank. This one goes on first, spring side outwards

    Dave, you need to fit the spare head and measure your squish on each cylinder first.

    It does sound like worn big ends.
