Thanks for the advice

Big sprocket looks quite good. The excessive amount of grease in this machine may have done some good.

Just ordered small and cutter sprocket from Outdoor King store. Cheaper than these parts were avail locally. My best price in WA was $53 for the little one and $92 for the cutter sprocket, plus $20 p&h

Goin to order chain locally as can get 3 meter lengths for $25. Just need to cut to length. Even considered making own sprockets, but not worth it given the two were only $100. That wouldnt cover the time it would take me to machine them.

Hopefully will get the chassis, chain cover and grass deflector into green paint before end of weekend.
