a simple
modification and have found it very good .....
Bob,
Not only good, it works amazing. I saw your post the other day and figure I'd give it a try.
I've been running my 912 80hp quite a bit working out some bugs before the first flight.
The most annoying "bug" is the throttle snapping forward so quickly when the engine was running.
I have the stock setup, except I have an ACS friction lock throttle on the pilot side. I left the T handle
on the passenger side. I have the friction block installed on the firewall and it was tightened up really
tight. It worked fine with the engine off but not while running. When loosening the friction lock on the
throttle, it would creep forward immediatly. With the engine stopped it did not do this.
I bought the spring at Lowes, used 2 hose clamps and a 2" length of 1/4 fuel line(split).
Took about a half hour to install. Drilling a hole in a brace I had behind the panel took the longest
because it was tight, but it was right there next to the T handle. The spring had long hooks at either
end, and stretched out to about 6" when adjusted perfectly. It hooks to the back of the panel about 1.5"
above and hooks over the fuel line with 2 clamps on it. Move the fuel line back and forth until there
is no force in either direction on the throttle then tighten clamps. Throttle is balanced with the engine
turned off and running! So simple but terrific results.Bob, thanks for posting this, my left arm especially.
