1986 Evinrude 40 HP VRO starting problems

[FinkPloyd]

Hello everyone.<br /><br />I recently came into a 1986 Boston Whaler with a 40 horse Evinrude VRO. It's been used very little and looks just about brand new. The last time the boat was run was about 4 or 5 years ago and the gas was never emptied out so it gummed up pretty bad.<br /><br />I've checked all the fuel lines and they look pretty good. I pulled apart the carbs and cleaned all the gunk out of them. I changed the spark plugs, got fresh gas and now I'm trying to start it. I'm able to get it running after a lot of cranking and it will only stay running if I keep hitting the choke.<br /><br />Anyone have any suggestions on how I can get this running? It's in fantastic shape so I can't imagine that there are any major problems with it. Thanks for any help you can offer.

Sounds like the carburetors are still gummed. Probably the metering orfices. Might check the fuel pump too.<br /><br />c/6<br /><br />Hooty

I think I'll give cleaning them another shot tomorrow but as far as I can tell everything seems to be pretty clean. There is a couple set screws that I didn't pull out because I'm afraid of setting them out of place when I put them back in. I suppose I can give that a try though.<br /><br />How do I adjust this badboy? I can't find a manual around here so I'm ordering one online but for the time being I have no idea how to setup these carbs.<br /><br />Fuel pump seems ok since the primer bulb stays pretty hard. I was able to keep it going for 10 minutes or so by tapping the choke.

Yeah,<br />That "tapping the choke" is what makes me think the carbs are still s/u.<br />Here's a link for adjusting the carbs on an Evinrude 60hp but it should work on yours.<br /><br /> Carb Adjustment <br /><br />c/6<br /><br />Hooty

Thanks a lot. I'll give that link a good study.<br /><br />FYI, I found out the motor is actually a 1991 instead of an 86 like I thought. Hopefully that will help me turn up additional information.<br /><br />Thanks again for your help.<br /><br />EDIT - Whoa. I just found something that may be my problem. I found a post on this board about a similar engine to mine. It mentioned the fuel control lever and where it should be set. I believe they are talking about the little red lever on the right side of the engine. Mine is set where it was when I got it. See my crappy diagram below, it's set in the first position.<br />

        1              2<br />(\|----------|   |----------|<br /> \\          |   |___       |<br />  \)         |  (____)      |<br />  |          |   |          |<br />  |----------|   |----------|

Where should it be set? Thanks again.
