Here's a few pics taken a few minutes ago after running this engine for the first time after installing it on the Cub. The engine has been setting pickled in my hanger for about a year now. I flushed out the preservation oil, filled with oil, rotated it a bunch with the plugs out to blow all the pres. oil out of the cylinders, installed the plus, dumped some gas in her, pulled it thru about 8 blades and she fired on the first blade....it took a couple of attempts to stay running but I had the throttle set at dead idle. After the 3rd attempt she was idling smooth(3rd times a charm). Oil pressure was instantly at 35lbs. and smooth as silk.
With that said, I let her run for a couple of minutes at idle before I gradually started to run her up to 1500 for a mag check. Both smooth,right smooth with 50 rmp drop, left dead!?? I assume the mag switch and not a mag because if it were just running on one mag I would not get any drop at all when I went from both to the right.
The switch is the old A.C. Type A-9 with off/batt/left/right/both in that order. Anything below right is dead, just like going to off. I don't know much about this switch, I am familure with the A-7 which I assume is the same thing only without the batt selection. I assume its like most of the A7's when they need to be took apart, cleaned and tweeked. If anyone is interested I would trade this one for an A-7.
Anyway, everything else checked good, no oil leaks, no fuel leaks, ran smooth, fuel shut off worked, all seems right in the world today,lol.
