Fire in Carb

My PVC valve is not working properly as oil is going into the carb plate. Carb caught on fire several times while I was starting up. The oil appears to be inbetween carb side meter plate. The meter plate to the float bowl side seems pretty clean.

To clean out the oil, can I do a deep clean by dipping the meter plate and carb into the carb cleaner dip? Air dry with compressed air? IS the carb salvagable?

After cleaning the carb and meter plate, I will change the PVC valve in the valve cover to the vaccum hose in the carb plate.

What kind of carb are we talking about? and what metering plate? Does the vacuum hose from the PVC valve hook to the base of the carb or a plate between the carb and the intake.
You cannot dip the carburetor unless it is completely disassembled and rebuilt as the cleaner will eat up all rubber parts in the carb.
You might have other issues other than oil being sucked into the carb base starting a fire as a spark would be needed to ignite it in the first place which would mean an intake valve is leaking or the timing is to far advanced.
The best thing you can do for it now is use a spray can of "carb and choke" cleaner on it.
Remove the carb and spray it down the venturi's and through the fitting where the PVC hose hooks up.
After you clean it and get it back on, you need to clean the inside of the PVC hose or replace it with a new one as there will be oil in it also. Then replace the PVC valve. If that doesn't help, you will need a complete rebuild (which includes a soak in carb cleaner) to flush all the oil and residue out of it. Hope this helps.

Another thing, the choke and carb cleaner is under pressure and spraying it in a carb and orifices causes it to fly out everywhere and usually in your face!
be careful and wear some safety glasses as not to get it in your eye's cause it will burn like hell ! Be safe!
