RE: Everything Radial Engines
Just for the heck of it you may want do a valve adjustment.I bought my 450 used from a known source so I`m reasonably sure it performs OK.I did do a valve adjustment on mine and found 2 valves to be tight on clearance and I did run engine after that and it ran great on the bench.I have engine mounted in the Gee Bee now and about to do ground testing and engine run ups.I still have to mount the electronic components and balance-I`ll keep those interested informed with new updates.
