The Silicon rubber diaphragm failed.

Rather that pay $500 for a new waste gate I am building a manual control.
Dan wanted a Manual control because the Motec control did not satisfy him.

His day job is 787 pilot.

It was an Audi part # 99/BA/ of all things.


We can use the waste gate we have now and couple it to this AC Spruce vernier mixture control
cable.  We will need a right angle mechanism as the fuel tank is in the direct way.
The cable will move twice as far as the gate. The gate moves .75 inches.

I'll machine the parts.

"The A-790-12 vernier mixture control is approved for Cessna 172, 172A thru Q; Cessna 150, 150A thru M, A150K, A150L, A150M; Cessna 152, A152. Other approvals pending. Order by Part Number and state Cessna model and serial number. A790-12 is 53" long."

"Special length Controls available per foot. 05-13280 $4.88/ft"

"Cable set-up fee for extra cable length."
"1ft to 10ft. 05-13276 $15.00"
"11ft - on 05-13277 $40.00"
