Hello all, just want to make sure I am on the right track. This is the first engine I have ever torn into so I want advice before I tear it up. I have a evinrude 9.9 1987 that I bought and the owner said ran great . When I fire the engine up, it runs for 3 to 4 seconds then dies. Now if I during this time pull and push and pull and push and pull and push the choke off and on the engine will continue to sputter and run for sometimes a minute or more. Now I did the basics and checked that the fuel pump was indeed pumping to the carb. Then I took the carb apart and found alot of gunk in the bowl. I soaked the carb in seafoam for about two hours then proceeded to clean the carb out with cleaner and finally I blew it out with compressed air. After reinstalling the carb it does almost the same thing. I would say it seems to run a couple of seconds longer but not much. I have taken it back apart to let the carb soak overnight but wanted to see if there was something else to try. Also I tried the pump the primer bulb trick while the engine was running and that made no difference. Thanks for the help.

Have a look at the top of this forum, first item is called "Top Secret Stuff" Look in there for answers to your questions. How to clean a carb. How to set up the needle valves and more. From what you are saying your carb. could still be dirty and /or your slow speed setting should be a bit richer. Best of luck. Rick.

By slow speed setting do you mean the adjustment knob on the front of the motor by the choke? I did adjust that alot if that is the knob. I tried it both directions and all in between. Thanks for the info.

Yes that is your slow speed adjustment. If making that richer isn't doing it for you I think your carb. needs more cleaning. Rick.

edit. Also have a look at this link. I believe it is a "must read" for anyone with a 9.9.

Wow that's funny, I found that website shortly after posting this message and found it very informative. Do you have any suggestions of where I might be able to find pictures of a rebuild on a carb? There are many posts telling me how to do it, but mentions things like the high speed adjustment and the low speed adjustment as expecting I am to know exactly where those are. I have a manual on the way so I suppose that will tell me, but it sure would be nice to see those pics now so I can identify all the parts. Thank you again for the response.

If you go to http://shop.evinrude.com there are diagrams of the carb in the electronic parts catalog.
