Re: 1970 evinrude 25 hp runs in gear but won't idle
The idle circuit of the carburetor *must* be clogged. It's passages are tiny and you cannot inspect them with a simple disassembly. Disassemble the carb, soak it in carb cleaner, and then blow out the passages with compressed air.<br />Have a look just above the throttle plate in the carb's throat. You'll see two or three tiny holes there. Those are the idle orifaces.<br />Is the carb adjusted properly? Start by turning in the idle mix control all the way in (gentle) then turn it out 1 and 1/2 turns. Start the engine and turn in the control slowly until you get the best idle. Then put the knob back on.<br />Good luck!
