RE: improved vibration
Hi gasayers,
what I guess could be worth trying is to get rid of the castor. According to my opinion it does no good to the SPs.
On my SP120 there is also a different feel in the gear when turning the prop. I do not know the reason, maybe its the different wear since its its always the same teeth that take the power from the piston.
But it runs smooth and powerful.
Cheers
