Re: Yanmar hard starting question
If you have followed the troubleshooting steps for the problem, and it is not low compression or injection timing, or one of the other mechanical issues try running the Power Service Diesel Kleen product through it. A lot of times you get some minor injector nozzle buildup that keeps the swirl pattern from being just right until the cylinders heat up a bit, the Power Service will help this a lot.
Just in case you do not have your service manual..
It is good to learn from your mistakes, but much better to learn from the mistakes of others...
