2000 70 hp Johnson 2 stroke - Carb ?, RPM loss

[luzzman]

I had idling problems, thought it was a fuel issue, blew the carb with compressed air and readjusted low idle on carb to specs. Idles better on initial start, but then goes into SLOW mode, can not get RPM up. Checking thermostat, plugs, wires etc per the forum. Question, when I pump the primer bulb on the gas, I can see gas trickling out of the 3 carbs, the bulb does get hard, is this right?

Not right, luzzman.

You could be overpowering the float valves with too much pressure or it could be poor float settings or leaky needle valves.

I would first determine why it is that you are going into SLOW mode. First verify that the engine is not overheating. Then disconnect the TAN temp wire from the pack. If all is now well, replace the temp switch. Also make sure that the TAN temp switch wire is not located next to a spark plug wire.
