Re: Carb ? Fogging?
I tried that winterizing kit the first year and did not like it since like Don says you don't really know if the stat is open, if if not the AF will go thru the exhaust but not into the block, so most people who use it drain a sample from each block drain to see if it does not freeze. To me if you are going to do that, you might as well just drain everything so you know for sure. My shop advised backfilling with no tox AF to reduce corrosion so that's what I do. I took the big 5 gallon container for the winterizing kit and turned it into a flush system for my trailer brakes!!!<br />About the drain plugs, I have never heard of them stripping, maybe you can spray em with PB blaster and let it sit, then go at it with the visegrips. Get new ones firs since they are brass (Soft)
