Hi Wendell,

I have an OS 1.60 in my Yak with a Perry pump. I only start it by hand with a simple back flip (Clockwise) against compression. To prime the engine I open the carby to full throttle and stick my finger over the venturi and then turn the motor over three times, bring the throttle back to about 1/8th open, connect the plug driver and back flip it. Normally starts first go. Now my engine is side mounted and yours is inverted. This being the case, I suggest starting the engine with the plane inverted only for the first flight of the day. Alternatively just use a starter for the first flight of the day.. From then on it should start upright without priming. You'll find that the mixture control will need to be leaned out about 3 turns from the factory setting. Sounds a lot but if you don't do it the engine will guzzle the juice.

Your plane looks good but... It would look even better if the cowl was painted white and blue to continue the fuse colours right up to the spinner. Also the canopy would look great in black. Just my opinion and everyone to their own as far as a colour scheme is concerned.

Cheers
Jason.
