I have a 1967 9.5hp evinrude and the only way it will start is to prime the carburetor but it stops shortly after, I checked the spark plugs. what else can i do?

most likley the fuel pump needs rebuilding. Start the motor with the gas down the carb and then use your fuel line primer bulb and squeeze it to keep fuel going into the carb. If it stays running , theres your problem.

With the motor in neutral, turn the tiller handle counterclockwise to the stop.

Then, pull the choke out and leave it until the engine is running but starts to cut out, then ease it in as the engine warms.

Your high speed jet may be clogged. The jet is directly behind and aligned with the float bowl drain plug. It gets clogged because anything that falls to the bottom eventually finds its way to the jet. Put a rag under the float bowl drain and remove the drain plug. Then squeeze the primer bulb a few times to flush out the float bowl.

Be sure that the gasket between the engine and the fuel pump is airtight.

OK I flushed the carburetor drain plug and that did not do anything. I can pump gas into the carb but it does not start, i don't think it is getting fuel. The only way i could get it to light is giving it a shot of fuel directly into the carburetor, is there anything else i can try?

We are not trying to clean the plug. The jet is behind and aligned with the plug. If you cannot get it open you will need to get a repair kit and rebuild the carburetor. You probably should do that anyway.

All of the fuel that is pulled through the carburetor to the firing chambers must pass through the high speed jet on the 9.5HP motor.

It works like this: The fuel pump and primer bulb keep the float bowl full;

The vacuum created by the movement of the cylinders opens the reeds and pulls fuel through the carburetor, mixing it with air;

Normal cold start requires a richer than normal mixture of fuel and air so we choke off the air to pull more gas until the engine fires;

When you need to artificially introduce gasoline into the mix, something is blocking the normal ability of the choked carburetor to perform that function (usually a blocked high speed jet, but sometimes due to a closed or improperly set lean/rich needle).

Hi, my motor wont start. I've choked it, checked the plugs. Now Today I figured I would pour some gas into the Carb and it started. But only until the gas was gone. Should I get a Fuel pump?
