High idle setting

Sat Jul 28, 2012 8:25 pm

What is the proper way to set the high idle? I put an electronic ignition on my 1977 184 and tried to set the high idle to 2400 rpm by putting more tension on the governor with the throttle control arm. This works but, the governor spring then seems to pull hard enough to overcome the friction of the throttle adjust cable and it just slows the fast idle down.

I tried the method in the book and backing off the maximum throttle speed adjusting screw on the governor but, if the throttle adjust lever is already at it's furthest travel you get no more rpms. Best I could get there was 2200 or maybe 2250. I can get the higher rpms by cherating the throttle cable but, like I said it backs off then. W@hat else can I do? Thanks

I pretty much had the same problem. I ended up tightening the throttle lever pivot bolt. IIRC, use a 7/16 open end through the RH side of the throttle lever slot, and a 1/4" drive with a 7/16 socket from the outside of the LH side of the pedestal. Feel up under there and you'll feel/see a hole that lets you get the socket on. Try it little by little, it doesn't take much.

Make sure you are measuring engine RPM's and not PTO RPM's. They aren't the same. The PTO turns slower than the engine.
