Well I put the carb in a part washer and got all the grime off the outside.:smile:



I got it mostly disassembled.



I could not get the brass tube out by the bowl.



I cleaned the parts and the carb the best I could with throttle body cleaner and blew it out with air. The needle for the float did not move and I had to remove it with pliers. Everything is moving freely now and the carb is back together. I will put it back on the engine and see if it works.:wink:

The 2 needle valves you use to set up the carb, is there a standard number of turns I can start with and once the engine is running adjust them to smooth the engine out?:confused2: Any information would be great.:smile:
You got it running? Sounds good so far. Is this one of those Briggs carbs with a high needle on top and the idle screw on the bowl? If so I rebuilt on a while back. It was the first big carb I'd ever worked on and I have to admit I was a little surprised when it fired right up ;)
IIRC you turn the idle screw in all the way and then back it out about a turn and a half and see how that works. You may need to turn it out a bit more. You'll hear it when it's right.
The high speed screw I think you set with the engine running at throttle. Turn it in until the engine spits and rns crappy. Turn it out until it starts to spit and run crappy and then turn it in about half as much as you just turned it out. Hope that makes sense. And if there a better quicker way then somebody is going to say so.

I go high speed fuel mixture, low speed fuel mixture, idle speed, then stop. If you go back and adjust high speed mixture you will have to adjust the other two again, as the high speed mixture setting affects the low speed mixture and idle speed. If the engine bogs down between low speed and high speed, open the low speed mixture screw 1/8 turn.

Here are some videos of the carb back on the engine and the engine running for the first time in about 20 years. Really smoked at first but that went away after I started to drive it arround.
