I know that the Impco regulator/vaporizor isn't factory for my 450 LP, but it's all I've got. Can anybody clue me in about servicing it without taking it apart? (and thus ruining the diaphrams). It apparently has an intermittent restriction on the fuel inlet side, because it will run really badly, then return to normal, then badly. I bled in propane through the intake, and it immediately goes away. I've checked all intake gaskets. Money is tight and I don't want to do a rebuild, I rebuilt it less than a year ago. Specifically, can the neopreen diaphrams withstand aerosol carburetor cleaner? Thanks.
