1989 70hp nissan. runs and idles and when we use the fast idle it runs fine but when you put it gear and go it will bogg down. it also serges when drivein. we barely choked it manualy and it runs fine. it seems like its not getting enough gas. replaced all gas lines and bypassed fuel pump. same thing. cleaned carbs. new spark plugs. nothing. did all the carb adjustment we could do but nothing made it better. when we let it idle then give it all it gots to go foward it goes real good then boggs down. it seems like carb fill up with gas then it burns it all out real quick. any suggestions. thanks... |

You have a fuel system problem if manually choking the engine helps. You have to go through the system one section at a time until you find the problem. |

Its service manual time or take it into a dealer. Due to the engines age and the fact that they do not make parts for that model engine anymore, I would caution you not to put any money into it. Think in terms of letting it go. |
