Hard to start and wont idle long. Mcculloch d195. How do you adjust carburator?
Check the air cleaner and muffler for plugging first. Turn both jet needles CW to stops (lightly), then back out each CCW 1-1/2 turns. Turn the idle speed screw CW about 1/2 turn. This is a basic setting and the engine should start and run. Allow to warm up, then pull the throttle full on and adjust the H needle CW til the engine speeds up somewhat, but is still 4-stroking. Correct setting is when the engine 4-strokes, but immediately 2-strokes when cutting. Release the throttle and allow to idle. Turn the L needle CW until the engine runs fairly well, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops moving, but still allows the engine to keep running. Hope this helps!
