Update.
Installed the new BOCA bearing , did it right this time. Reassembled it and fired it up using some SIG 15% Champion and an idle bar plug.
Nice engine, got it to idle down to 2000/1900 easy peezy good transition and good power. Then switched to an OS #7 plug just for giggles and still got a good steady idle and 12,000 rpm with an 11X6 MA 3 series running plenty rich. Seems like a decent engine , I rate it higher than the typical Magnum that I have tested (but understanding that this is just one example of an Evolution so my sampling rate is much smaller than my Magnum rate) but I would not buy it over a similar Thunder Tiger based on my experience. Although it does have the cool fin design.
