I checked out the .15 OS Max III I picked up at a swap meet for my Quaker. After a bit of coaxing I got it to run. It responds to high end adjustment well and transtions ok from idle to full throttle. One problem I had and this was my fault, is that I should of backed out the idle screw so that I could fully close the throttle to shut her down. I covered the throat with my finger and it still would not shut down just kept idling. Is there a problem here or is it because the air bleed needle is backed out far???? Also I have a few questions:
1 I was using 10% nitro and my club is selling 15% ( said it was good for 2 and 4 strokes).....what nitro content would be good for this engine??? Higher then 15??? Would a higher nitro content.help in ease of starting and performance??? 2 High speed adjustment should be to find max revs back off till it runs rough than slightly lean it??? If I am correct these engines should run rich due to them leaning out while inflight?? 3 Glow Plugs: The LHS recomended OS A3 plug for lower nitro content. I would assume hotter weather and/or higher nitro one would need there cooler plugs???? What would you recomend??? Thanks Mike R- posted
