Last Tuesday was my Final Inspection by the Transport Canada delegate. All went fine with no snags. Just waiting for the Certificate of Airworthiness now....

On my 650 I have an 0200A with 2 inline faucets pumps. On one pump I get about 5 PSI of pressure. On 2 pumps I get more than double that. I read that normal pressure should be between 3.5-4.75 PSI in the Continental book. Is there any risks I blow something in the carburettor at that higher pressure? Anyone else using this config?

CH650B W&B Question. On the W&B calc sheet, a note puts the Datum line at Station 1790 mm. along the leading edge of the wings. To my knowledge, Station line 0 should be the aircraft centre line. Or should I measure this from the side of the fuse? Ideas?

I am building a CH650 and I am planning to use the engine from my old C150 (O200A) that was overhauled 3 years ago. The O200 does not have any mechanical fuel pump on it. It was feed by gravity (high Wing). Anyone has any data on this type of arrangement - converted to low wing? I was thinking of a Primary Electrical Pumps and one or two back-up pumps. Any ideas are appreciated.

Tks
