That would be for the diaphragm fuel pump in the walbro carb. It needs engine pulse to work the diaphragm , which in turn makes the internal path ways of the pumper carb work correctly to the jets.

Anyone know if theyre are known issues (blowing crank seals) when adding reeds with just port matching and polishing? |

How did you make that hole to the pulse of the carb? You drilled a hole directly to the motor? And if you one day put back the old carb?
thanks |

Look, how did you put the pulse to the carb? You drilled a hole directly to the crankcase? |

If he wants to go back to the original carb he can just put a screw in the old hole that was drilled into the motor. No big deal. |

Then I epoxied a piece of tubing in place so I could attach a hose to the port. I had the top end off the motor so I could prevent the drill shavings from remaining in the engine after the mod. To reverse the mod either epoxy the hole shut or insert a bolt into the other end of the tubing... -Justin
