Doctors update. At the end of 2018 I took 5 of our West Bend 820's apart. Each one had a failed taper crankshaft. The crank pin on each one had a chatter/wear mark right at 11 o clock. After some head scratching and doing things like Rockwell testing I was not sure what was the problem. I had been running 10 oz of Klotz KL 100 (80% synthetic 20% castor) in alky. I decided to make a switch. I started the 2019 season running 11 oz of Klotz BeNol straight castor per gallon. So this week I've finally gone through all 4 of the 820's we ran as duals in 2019. I'm happy to report that all 4 crank pins look perfect.
