When I first ran into this issue I had and old starter and old battery. I have since replaced the starter and battery but still have the same issue. I have also tried other known working batteries with the same result.
Before I tried starting it, I did prime the oil using that long tool and a drill.
I have also tried jumping the starter but it results in the same noise.
It is a low compression 8.5 or 9 :1 (cant remember exact number)
The motor does turn a bit but just not enough.
Thanks for the suggestions so far.
