I have just finished my second gallon of fuel in my new Saito 100. I am running this engine on an UCD 60, and all I can say it is a fantastic engine. Started by following the break-in prochedure to the"T", I have gotton my low end down to 1900 r.p.m and the high end at 9600 r.p.m on a 16X4W APC prop (Peak at 9800 r.p.m). But I have two questions.

I adjusted the valves yesterday, and with this engine being inverted the valve covers were full of oil. But this was not clear oil but some rather nasty looking stuff. Is there any long term problem with this?

This Saito, when primed properly, will start on the first flip every time, but 6 times out of 10 it runs backwards. I am back flipping it, but it dosen't seem to make any difference. Your help would be appreciated.
