RE: MOKI RADIAL Care and Maintenence
Alex,
If the engine has that much run time the larger pitch should give you better performnace in the GeeBee. I run a 32 x 18 on my new 250 (5 - 10 hours runtime) with good results. I would pay very close attention to engine temperatures in that kind of heat.
You are correct on the starting procedure. I'm lazy, so I use a 24 volt starter on mine, instead of proping it by hand. With the compression stroke in multiple positions, its a bit different then a standard two stroke.
The grease that gets into the air pump line is from thats applied to the cam during engine assembly also some of the residual oil from the gas/oil mixture. The tube should be clear, if its not replace it. (3 mm) Greasing the cam is not a routine maintenence item, but cleaning the tube should be done periodically. Remember, any blockage of the tube will severely lean and overheat the enigne.
