Hi everyone, I spent the last year restoring a classic 1972 Glastron GT-160 and finally got it in the water last week. I re-powered the boat with a re-manufactured 125 hp 2-stroke outboard. I've had it out a half a dozen times and the engine seems stronger every ride. But here's my dilemma, The warm-up lever on the throttle control box (and this one is designed literally a lever) that controls the rpm's while the engine remains in neutral doesn't seem to be functioning. When the motor is running in neutral, if I lift the lever all the way up, or push it all the way down, or anywhere in the middle the rpm's never change. In fact, the way that I've been starting the motor without it stalling is to take off the motor hood and fiddle with the vertical throttle bar directly on the engine which helps it rev up a bit. Once the engine is warmed-up it runs really well at idle, with no stalling, and it re-starts easily (without needing assistance of warm-up lever but a dash of choke).
So, I'm trying to figure out how the how the warm-up actually works. Is it electronic or mechanical? Is it attached to the throttle cable itself somehow. When the lever is lifted up how is it connected in the throttle control box and then how is it connected to the engine. For some wacky reason I can't seem to find the information in my service manual or on the net. I was hoping someone here could help me understand how it works so I can try and troubleshoot it. All the best from Keith in South Norwalk, Connecticut.
