Everyone on this site is either here to help or needs help. I've saved thousands of $$$ by seeking advice from others who have the expertise and knowledge I do not. I've also made critical mistakes on my own or from another's direction because, in both instances, I lacked experience and insight to some of the pitfalls. It's sort of like giving directions to open up a tube of toothpaste - you 'assume' the person wanting to know how to open it, will not squeeze on the tube as they unscrew the top.
The point is that it is CRITICAL to provide complete information when giving direction and for users to beware. Obviously all potential problems cannot be captured ( see below ). We all need to have enough humility to know that there's more than one way to skin a cat, and our way might not be the best way, or a common practice - but its worked for you...
For me, I was turning the crank bolt and it was not turning the engine. I did not know why at the time, but realized later ( thankfully before I kept trying to tun the bolt ). I was unable to winterize my engine so I drained the raw water in my engine via the Schrader valve/ air pump. Water dumped out of my engine BUT - unknowingly, it did not come out completely from my raw water system hoses, or raw water pump - so, the impeller in the raw water pump housing was frozen... and, the engine would not turn. Being a novice, I did not realize this. ( I'm still stumped at why the Schrader / pump did not blow out the entire system and protect me from this !!!! ).
Bottom line - I thank everyone for their help. I winterized all and will refocus on finding TDC in the spring. Just glad I was able to find the issue - I would not have without help from this site ), and that I did not "F" up and do more damage by either cracking something in my cooling system due to ice, or snap that bolt by being frustrated and heavy-handed.
So... isn't that bike pump/ scraper valve supposed to dump all the raw water in the system ??? Thank G*D I found this quick... before ice did... what ice does...
