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 loos
ening the friction lock on the
throttle, it would creep forward immediatly. With the engine stopped it di
d not do this.
I bought the spring at Lowes, used 2 hose clamps and a 2" length of 1/4 fu
el 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 spr
ing 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. Throt
tle is balanced with the engine
turned off and running! So simple but terrific results.Bob, thanks for pos
ting this, my left arm especially.

Throttle handlI've finally found a good use for the Zenith
I did the same thing --I removed the copilot throttle and attached a
spring to a short piece of throttle wire that penetrated the firewall
for the copilot throttle, then attached the aft end of the spring to the
instrument panel with a nylon tie wrap. It's a simple matter of slowly
tightening the ratcheting tie wrap until the right tension is achieved.
I've been using it for a couple of years with no problems. It works
really well !!!

Yes , I use the original Zenith T-throttle in my 701 with a simple
modification and have found it very good (over 170 hours now). The fix
is to install a counter balance spring behind the panel which unloads
the spring force from the carb's. With proper adjustment the throttle
will not creep and requires very little clamp force on the nylon
friction block. One end of the spring is anchored to a small bracket
using the same rivets that hold the nylon bearing in the panel. The
other end attaches to the throttle rod with a small C-clamp that
compresses a short piece of rubber fuel line (split) and is adjusted to
load the installed spring so the throttle does not require any force to
hold position. It's simple, it's cheap (Lowes has the springs) and if it
breaks the worst that can happen is the throttle creeps to full power.
This design avoids the Croke effect also.
