Hello. I have a Yamaha Deto 50hp 6h5 year 1988. The problem is ignition. I tried to search the internet for a service manual for this older model, but nowhere to be found... I have the manual for the newer model -> 1989 onwards and it says that the correct values are 5°ATDC and 25°BTDC . Are those settings the same for that older model? Does anyone have that manual and could post a picture of the ignition adjustment instructions for me? I would be grateful. Thanks.
