Tore down my R8831A to soak in Berrymen overnight and all day today. Check ball did not fall out during disassembly. I figured it would turn up in the solvent can or come loose when I take it out of soak. No luck. Figured it was lost until i tried to blow carb cleaner down the hole. It was still in there. Put old pump cup on a pin punch, filled pump cylinder with carb spray and tried to 'pump' it out. No good. I slid an old fuel line over a blow gun, wrapped a big ball of teflon tape around it to make a seal, shoved it in the pump bore and pulled the trigger. No good. I poured a little acetone in the ball hole and the cylinder and let soak a few minutes (I'm sure it was eating the finish off the fuel bowl). I'll try blow gun tomorrow night after the residual acetone has evaporated. I don't hold out much hope. I entertained heating with a propane torch. Not sure how stupid that is. Also, what is 'staking?' Locktite? Red Head? Something else? Any advice is greatly appreciated. |

Does it need to come out? |

yes. (it is the root of the problem that precipitated the tear down: no pump shot.) |

staking is when you use a pin punch to mess up a good fit so the ball wont move. |

to clarify: I didn't touch the punch to metal. I stuck the tip of the punch in the hole of the cup, and used as a piston to compress carb cleaner into the passage with the ball in order to dislodge it. |

I read on the Mike's Carburetor blog that reasonable heating is ok. I flipped over fuel bowl and heated approximate location of ball with propane torch from inside the carb throat while tapping with a screwdriver handle. It fell right out. |
