The Stovebolt Site Forums The Shop Area Engine Shop stuck power piston in rochester b

i have a old b that i bought a while back that has been sitting for years. i started a rebuild but the power piston is stuck inside the air horn. anyone know a good way to get it out. i am letting it soak a little with some carb cleaner i sprayed on it in hopes it will pull out. also this carb has a brass tube below the jet that's not shown in the 63 shop manual, can this be left in? looks like it would be better for it to come out before it goes into the carb bath. thanks, hr

I would try a heat gun on the housing. I am talking about the gun that is more or less a pumped up hair dryer.

Are you talking about the nozzle in the bore? Personally I wouldn't take it off because I would guess it is pressed in.

thank you truckernix, that worked like a charm! i had a heat gun so that took care of it. it looks like it's pressed in. i don't remember seing this in any of the other b i have rebuilt, but it's prob been 4 years or so since i have done one. i don't see a picture of the brass tube in the 63 shop manual but i will just leave it in to let it soak. thanks again.

When mine was stuck, I soaked it with carb cleaner. After several soakings it was still stuck. I carefully tapped the end with the plastic handle of my screwdriver. It seemed to be moving so I soaked and tapped until it loosened and came free. No damage done.

well the heat gun trick really worked. i just hope i will remember it if i run into it again.
