5hp help

Ok. Preformed as usual. After it died I pulled the plug. It was surprisingly dry and lightly sooted. I've ran way worse before. It still had spark. Only adjustment is shown with the red arrow in the pic. Screw it all the way in and it dies. I've backed it off 1 1/2-2 turns. It runs great when it's running.

The screw is the idle mixture. When it dies try spraying a small amount of starting fluid into the carb and see if it fires for a few seconds. If it does you probably have a fuel pump or fuel pickup tube problem.

PROBLEM SOLVED!

Hopefully this might help somebody in the future. Ended up being the tank wasn't venting. Took off the cap and ran it under a load for a few minutes until it sloshed out and I shut it off in the name of safety. A couple well placed drill holes in the cap and it runs like a champ now! Ran it for half a tank of fuel with numerous stops. Started on the first pull every time now!

Thank you all for your 2 cents worth! These carbs are stupid simple. What clued me in was the dry plug. It WASN'T getting fuel yet the carb had plenty.

Briggs made a screen cup deal that went over the main jet fuel pickup tube. That was a huge step in the right direction. These carbs and tanks need to be spotless in order to run correctly. Can look inside the tank and think it's clean. Get some readers on and see another sloppy mess LOL.



Glad to hear you got it running.
