Re: Yanmar 2gm20f
Welcome aboard, hopefully shortly you will agree, you have a good little engine there.
Was the motor running for the previous owner this past season
or was it not in operation for a period of time?
Did it run ok when run prior to purchase? or did you run it prior to purchase?
Does fuel shut off cable on the block not move, as in frozen, or does it move and still does not shut off?
Check the position of the compression release lever on 1st cylinder,
it should be in the same position as the 2nd cyl which is firing.
Do you have a service manual?(same for 2-3GM's) thinking you
should be able to download online?
