Hi,
My boat engine is a 1992 Yamaha, 60 HP, I bought it not long ago. There are problems with cold start. Prime-Start system and oil injector. The engine ID is 60F EMO, 6H2-L, 500850 (B=1992). It starts with difficulty when cold and when it starts it stops after 1-2 minutes, then I restart it and it works. It starts very well when warm. What are the two pipes on the Prime-Start system? One thinner and one thick. Both go to the crankcase. Carburetors are clean, spark plugs are new.
Should the CDI box pointer be on the first line when idling? The CDI box on this model is very interesting. I couldn't find anything like it anywhere. According to its manual, which I found online, the distance of the CDI indicator rod is 120mm, but this is impossible, because it is at least 128mm fully wound. I set it so the throttle is just touching the roller so the CDI pointer is on the first line. This is correct? Thank You!
