Question
B&S photo
B&S model 130292, Type 0159. This engine is on my tiller. I got it started once last summer. While running, gasoline leaked out around the choke at the very end of the Pulsa-Jet carburetor.
This year it wouldn't start so I replaced the points, etc. Got a good spark but the engine wouldn't start. I sprayed a bit of starting fluid under the plug and the engine started with 2 pulls of the starter and ran for a few seconds.
It wouldn't start after that. The fuel tank is 1/2 full. After pulling the starter several times, I checked the plug and it was dry with no odor of gasoline. Then I put a bit of gas under the plug and again it started and ran a few seconds. Within seconds of putting the gas under the plug, some of it was leaking out around the choke at the end of the carb. What causes this leakage?
With a dry plug, fuel obviously isn't getting to the plug. What causes that? I was going to remove the fuel tank and carb to clean the carb, but there is one screw I can't get to for removal. Enclosed is a photo with a red arrow pointing to this screw. How can I get a screwdriver in there to remove that screw?
The yellow arrow points to a gasket where the carb connects to the engine. It appears to be a bit worn. Could that cause the starting problem.

New Arrows
You've got the right idea. The carb is probably filthy inside. The carb may or may not need to be replaced. To remove it, I normally remove the gas tank. To do this, locate the two phillips-head screws which secure it. I'm returning your photo. The screw needs to be removed by angling the screw driver. I suggest using a long, narrow one. The green arrows on your photo indicate the gas tank screws. The orange arrow indicates a needle valve screw. Turn this screw an eight-turn to the right (Clockwise). This will allow a bit more fuel into the engine, increasing power and performance, and making the engine easier to start. Finally, the white arrow indicated the gasket between the gas tank and the carb. Replacing this will allow more fuel flow. Hope I helped! Let me know how it goes.
