Bolts to fill the PC holes

Post by CajunMike »

Anyone know what can be used to plug the Pollution Control holes on the top of the cylinder on a 79 Carb model? Way back the PC system cooked my air filter so we welded the PC valves closed, but left them in place instead of trying to find a bolt or something. Not very sightly but got the job done. About the size of an oil pan plug bolt? Any suggestions?

Thanks,
Mike

they are standard metric threads... do you still have a reed valve in your hand? you can take that to AutoZone or Auto Value, or Advance Auto, etcetera

metric oil pan plugs work great. sorry, cannot remember that thread size off the top of my head.

To plug the four air injector holes in the cylinder head, you can use p/n 99642A205 from McMaster-Car. Five to a package.

Thanks for the suggestions. Ill pop one off and head over to the local auto zone or hardware store and see what I can find. Nothing like creative engineering.

as i recall, they are the same size as the nut that holds down the dizzy, 17mm.

i really don't think my crow foot selection goes up to 28mm, does it? according to http://www.craftsman.com the standard set only goes to 19mm, and i know i have the standard set.

My reed valves are a lot bigger than 17 mm. Oh well, still searching.

I think they have a smaller hex on the bottom under the valve. If not, try a leather belt, wrap it around valve and around a ratchet and extension.
