Hey, guys
I have an 1984 200es running very rich, smokes like its burning coal. smuts the plug, not wet like oil but dry smut black. I have cleaned the carb 3 times today.
I have verified it is clean. I can turn the air fuel mix screw all the way in until it bottoms out, and it will still run! and still puff coal at any position.
I checked the factory main jet is a 95. all passage ways are clear, the e-clip is on the 3rd notch. I have blown air through all of them and ran a wire also. I ran it with no air filter, no box just to lean it out, no help. It starts and idles, if you roll on the throttle slowly it does increase rpm but bogs under a load at half or more throttle.
I checked the timing, and its spot on the pick-up is lined up with the button at F-T on the flywheel.
Any thoughts, before I order a new carb or a shindy kit?
Thanks
MrC.
