hi all

i have a pretty new jetcat p20sx engine with 1hour 42 mins runtime on.

on the last start i noticed more of a noise when the starter motor was engaged and also when it was on cool down.

would this mean that the small rubber o-ring needs replacing on the starter already??

if so is it an easy job to do??

thanks

I would say that the O ring is possibly contaminated with fuel and needs cleaning rather than it being worn out.

My Feedback: (1)

Mine was knackered in about the same time.

O rings are sized from the inside so you want a 2mm section with a 3mm hole (so 7mm OD) Viton by the way.

Undo the screws on the motor housing and lift the motor out and pick out the old O ring and shove the new one in.

P-20 is heavy on O rings, motors do vary as the P-20 pre-load also varies, tight motors that do not spin freely do eat them.
We keep a good stock of o rings

Worth a try. I always keep a bottle of break cleener in my toolbox in case I mess up with fuel in one way or another. Just make sure to wait a good 10min efter cleaning for the fluid to evaporate.
