Pouring Oil Into Carbs and MFI to Winterize
Have any of you fellow easterners tried this winterizing technique? Haven't heard of it before, makes me wonder how difficult it would be to restart.

... 5. Remove air cleaner. Get a quart of the same engine oil which you are using for the engine. Make two holes at the top of the can (about a half inch in diameter) so that you can pour oil easily into the carburetor air intake port.
(a) On all 356 models, hold engine rpm at about 4000, then pour half a quart of oil into the left side, the other half into the right side of the carburetor intake ports. The engine will probably stall when you are pouring oil into the right side. This is completely normal. Let your engine stall. Don’t restart it. Just shut off your ignition and reinstall your filter. Obviously there will be a lot of smoke coming through the muffler for a couple of seconds. Don’t be alarmed. Your engine is now completely winterized.
(b) On all 911 models except CIS, hold rpm at 4500 rpm and pour oil into the six intake ports regardless of carburetor or fuel injection system. Make sure that you distribute the one quart to your best ability equally to all six intake ports. If engine stalls, proceed the same way as outlined earlier on 356 models. Do not restart. Before engine stalls, however, each cylinder should have received a minimum share of the quart of oil. Shut off the ignition and reinstall your filter. Your engine is now fully prepared for storage and in the spring you can start up your engine without having your spark plugs cleaned.
(c) On CIS and 914 engines, the above method cannot be used. On these, pull plugs, squirt heated oil (about 70°F) in plug holes, crank a few turns and reinstall plugs.
