You can go through alot of plugs if you plug the exhaust to shut it down. Next time you go to fire it up it's dead.
If thats not it it's probably a tuning issue, possibly too rich on the bottom and lean on top. Set the idle gap at .7 mm and use the lsn to get the desired idle not the idle screw.
I have heard the Os p4 last longer than the p3, I am using Odonnell 97t and 77t.
