I recently bought a Yanmar 186D which overall appears to be in good shape. Original paint, no signs of heavy wear or abuse, etc.
However, it is very difficult to start. Worse on a cold day but still difficult on a day in the 60s.
Symptoms:
- requires multiple cycles with the thermostart and lots and lots of cranking
- while cranking it over it has a lot of thick black smoke
Things I know or have noticed:
- once started, runs fine and no smoke
- re-starts easily
- idles low without any problems
- seems to have ok power
- thermostart gets hot and the little reservoir has fuel
Looking for any troubleshooting suggestions. As of now I was thinking next steps would be to replace the injectors and measure the compression. Any help would be much appreciated!
Also, is there a service manual available out there for the 186? I found the parts book but no manual. Thanks again.
