Damn 'n blast. Hit one of the larger rocks (bed rock...) in the "lawn"
with the blade of the rotary mower the other week. Sheared the
locating pins on the diecast boss, neat I though saves the engine.

Got a new boss and blade and fitted them, started it up and boy is
there a lot of vibration. Check the new blade for balance OK. Dreaded
thought output shaft bent, mower up on blocks, engine started. Oh
dear... there is the shaft wobbling nicely by about 3/16". The B&S
10D900 series engine is "lumpy" and hunts but then it has no load,
with the blade fitted and a short run of mowing it didn't seem to bad
considering the vibration...

What does the panel think are the chances of:

a) Straighting the shaft in stitue.
b) Other engine damage.


Hi

I'd want to use something a lot more precise than a damn lump hammer.
I've strightened all sorts of things up, but I wouldnt think of doing
it with a hammer, you need controlled.

At the end of the day if it runs, all you need do is minimise the
damage, no need for perfection. - having not seen it I might be
missing something of course. Some say I am anyway
