Carburetor re-build question
Hi guys, so in the process of re-building my Rochester BB from my 51 Olds 98 Rocket. Everything was moving along smoothly until I got to the part where I have to remove the pump piston (the instruction set with the kit calls it a piston and spring), In my maintenance manual it looks like they refer to it as the pump discharge guide, spring and discharge ball.
Unfortunately it's stuck and there is no way it will slide out (car hasn't run for about 17 years) Anyhow it's in there very tight, have tried every penetrating oil but nothing will make it budge, I was able to tap it down a little so it does move but they were pretty forceful taps and now I've knocked it further in. I was hoping that someone might have an idea on how to remove it or has come across something similar? I'm very close to drilling it out but not sure if there is an easier way?
Thanks, Ron

Compressed air on the nozzle(s)?...be careful it may rocket itself out!
Try SLIGHTLY warming the area surrounding the piston with a heat gun, put more penetrating oil and walk away...repeat...repeat...
Good luck!!!

Thanks again everyone for the suggestions, Chris this was also what I was thinking but doesn't appear to be a replacement part in my re-build kit so if I screw it up will really set me back. There is no plug at the bottom Oldolds88 but in my research I've read a couple of guys saying basically the same, to drill out from the bottom, poke out then fill with JB Weld but again if I don't hit the spot exactly could be a big setback. The good news is I'm soaking the whole carb in Pinesol and it's surprisingly working really well (except for my problem!)

I got turned on to Fluid Film, picked up a can at Home Depot. Better than any penetrant I've used so far. Good luck
