Tri Power

I have a tri power setup on my GTO. As usual i went out for a ride and came back with smiles. Strangely when on my cruise the carbs decided to run on high idle. if I tap the peddle in neutral it would kick down. As soon as I would give gas she went to high idle again. Could it be the sensor on the choke? Any Tri Power nuts out there? Not a real high Idle just up an rpm.Has been fine up till now…so I checked the linkage for hanging up. Seems to be fine. I did run a 1/2 tank of cam 2 fyi. Thanks Red

things to check.

with the engine at normal sidle speed turn the engine off then note position of center carb throttle, then move the linkage thru the operating range and see if it returns to correct position, and also check the end carbs for idle position. check the return spring and linkage for binding. The choke operation has a cam to increase idle position speed when cold, the choke could be causing the problen, and if it has vacuum choke pull off piston that could be stickey. I would have to look at the carb, This might be time to get rebuild kits,. clean and check adjustments . Sometimes a back fire can cause butterfly problems.

I followed most of these steps minus the running at idle and shutting down ( good idea ). Defiantly is something hanging up, happens while hot actually or cold. Found a lose wire on the choke sensor last night. Ill run through it again today marking some linkage locations as suggested.

Your choke should be a hot air type. No wires to it unless someone converted it to an electric choke. If they did then you'll need to make sure the power to it is a full 12v and the cover is grounded properly.
