Toro 223D engine problem

Getting the wrong parts can be a pain I know, you did the right by testing the plugs nice to know its all working out, thanks for letting us know the update:thumbsup:

Before, I had trouble starting even when warm, I had to hold the glowplug switch down. Now when warm, all I have to do is hit the starter, and it fires right up. That extra speed from the new starter has made it seem like I put a new engine in it. And no smoke when starting. Discovered my steering cylinder is now leaking. Going to get underneath it today and see if it's the cylinder or a hose leaking. Even with all the little things I have had to fix, this is by far the best mower I have ever owned.

Am sure you will able to replace the cylinder seals and O-rings or replace the bad pipe (hose) lots of videos on utube..!

Well, the Toro 223D is back to almost not starting. Cold, I have to grind on the starter a long time with tons of black smoke. I have to play with the throttle and the glow plugs while cranking. Once (and if) it finally starts, lots of black smoke then finally clearing up. Retorqed the head, reset valves, replaced injector nozzles. No change. Could the injector pump itself be the problem. It seems to be getting progressively worse. I have a Dahatsu diesel engine in a Toro Z Master parts machine that runs good. Thinking about giving up on the Mitsubishi and swap the Dahatsu in.

Service book on Mitsubishi L3E engine in trouble shooting section, says the first thing to check for excessive black smoke is adjust smoke set. No where in the manual can I find hoe to adjust smoke set. Anyone have any idea what they are talking about?
