"I have a 56or57 Evinrude Lark

"I have a 56or57 Evinrude Lark 35 HP. It runs like a top most of the time. The last two times I have taken it out it, it has quit. It will run fine until all of the sudden it will act like the choke is pulled completely out and die very quickly. When this happens, gas runs out the front of the carb and down the bottom of the intake. The gas continues to run for a few minutes even after the gasline is disconnected. After sitting for a day or so, it will run fine again until it does the same thing over again. Any ideas? Thanks."

Remove. clean, and rebuild the carburetor with a complete carburetor kit. Don't wait for the engine to catch fire.

(Carburetor Adjustments - Two Adjustable N/Vs)
(J. Reeves)

Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.

Setting the high and low needle valves properly:

NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.

(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.

(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.

"Thanks, I had a feeling that a carb rebuild would be the answer. Hopefully that will solve my problems. What is causing the fuel to come out the carb though? Thanks again."

Flooding.... faulty float needle valve and/or incorrect float level.

When assembling the carburetor after cleaning......

(Carburetor Float Setting)
(J. Reeves)

With the carburetor body held upside down, the float being viewed from the side, adjust the float so that the free end of the float (the end opposite the hinge pin) is ever so slightly higher (just ever so slightly off level) than the other end. And when viewed from the end, make sure it is not cocked.
