I don't have my 20B running but, my friend who was a sedan class racer in an RX3 left his on despite using premix. He thought, incorrectly as it turned out, that he had to have it on there for the rules. His made some noise because the drive was packing it in. We pulled it all off and never looked back. He had plugged the intake, and there was no oil in it and it consumed it's own guts. You should probably take it off to check. Several guys have run Richards conversion plate with no problems. It always seemed like a good idea to me. With oil in them the pumps are pretty reliable.

I was running my 20B and noticed a high pitch whine. My first thought was an alternator bearing. Course its a bit hard to all with all the exhaust noise....anyway, upon closer inspection it is the metering oil pump making the noise. I'm running the adaptor from Richard Shon (I think thats the right spelling) for an outside oil source. It seems to be working fine, but the noise bothers me. Anyone else run across this?
