My battery was starting other motors just fine, it’s from 9/24 so pretty new. I removed the lower last night and tried it still no change. But before I called it a day, I had a thought. When you go through an engine and use engine assembly lube (as you should) and you let it sit I have heard and seen times where the lube/grease they used will harden and make the engine hard to turn or not turn at all. I am out of aft at the moment, so I mixed up some sae30, acetone, and some penetrating oil and I poured it down the carb right into the block. and I have let it sit to try and turn the engine assembly lube I used back into lube if that was the case. I haven’t heard of that happening to the lube I use but it is worth a try, I use Permatex ultra slick engine assembly lube. I thought I ran it long enough to break it down/run it through and replace it with 2 stoke mix but I might not have.
I just went out to see if that fixed it and it works perfect, I have tried it 5 or so times now and turns over better than ever!
OK, so it is not the gearcase. You have run the engine already, so any grease/installation lube would have melted off by now.
Once again, you mentioned a very low voltage reading while cranking. Are you using a 6 or 12volt battery/starter? If you are using a 12 volt battery/battery, there is an issue somewhere in the electrical/cranking system
PS: The battery may be “OK” but has inadequate capacity/cold cranking amps to power your starter…Again, always best to start at the beginning, check the battery…
