I have my Murphy Moose Quick build ready to fly after just 3.5 years and yesterday pushed it outside and cannot get it to start. I have an M14B with a P nose case V530 prop M9-35 mags Savage Magneto harness Slick Start I got the air start distributor out of time because at some point I thought I would remove the tach gen housing and put a plate over it ( a buddy has an M14P with electric start and we put a plate over it). When reinstalling the tach housing the air distributor gear slips back and no longer turns the distributor. Anyhow I set the timing but am confused as to the 1MM reference in the manual. Direction of rotation also seems a little vague. My air start turns the motor but peters out at at about 500 psi. I got it to fire just once. I timed the mags using George Coy's timing procedure which is the only source I could find - pretty sure I did it correctly but now perplexed. Any words of wisdom would be greatly appreciated as I need to push it out of the hanger into the cold today or tomorrow.

What prop flange angle did you use for setting the mag. firing angle? 2. What number is stamped on each mag housing under the distributor cover?

I have not seen a Russian fixture but I was able to modify the Chinese tool. Part No. H6G 816 in the Chinese engine parts manual. Joe
