In search of ideas for a 225 /6 refresh....

I originally bought a Cloyes timing chain set for my 225 but after installing it the excess slack in the chain was staggering. I was going to piece together a roller chain and individual sprockets from NAPA but eventually found a Rollmaster.
Wow! Double roller with nice sprockets and the crank is keyed in 2 degree increments. I believe it is actually made in Australia and the PN is CS5302 but I'd have to check my build thread to verify. I think I paid just over 100 US dollars and worth it.
Should be easy for you to source down there.
