motor trouble

[draggin bait]

I have an old (mid 70's model) Evenrude 70 hp outboard. Last time out, it suddenly started running RUFF. Can anyone recomend someone to troubleshoot it for me that wont take me to the cleaners? I live in norfolk. Any help would be appreciated. Thanks

Before taking it to anyone, have you looked at anything like spark plugs, water in gas (water due to Ethanol issues are popping up everywhere these days) or tried a decarb? If not, you might want to take a quick look yourself 1st.

I looked at the plugs and they looked fine. I ran the boat abut 7 miles before it took a dump on me. It was the first time I had it out this year though. When I put it up after striper season, I ran the gas out of the line and put stabilize in the tank.

Even if the plugs looked good replace them.

it has a miss in it, and when I hit the throtle, there is no increase in speed. The rpm's don't increase much at all.

Check your fuel filter screen maybe its pluged up.

Get a torque wrench, get the torque specs for the spark plugs for your engine. Probably 18 to 20 foot pounds.
Two cycle engines are tough on spark plugs so replace them before trouble shooting. Its a good idea to replace them at the start of each season.
Make sure the o-ring on each end of your gas hose is in good condition.
If it still has problems then we can go to the next level.
If you want some one to fix it for you, I'd reccomend Steve at Colley Marine on Shore Drive.

I think you probably got it fixed by now, but if not, Steve is an honest fair dude who has treated me well in the past with an evinrude motor. The old Colley Marine storefront on Shore Drive (near Lesner) is vacant now. Steve is behind that store in a warehouse looking building. Call him and tell him the same thing you told us in this post and if he can't tell you over the phone he will have you bring it in. He's a great dude. Never has let me down.

I had similar issues and it was the oil/fuel mixture.
