As glycerine and alcohol can get washed off by water condensation in air I did not see any benefit of using that combo. My approach was clear chain lube , the sticky kind with solvent. Add a decent cu ...

Did you check the primer jet for a reasonable spray forming, a poor running down of fuel from there is not great for starting ?

No matter, how much you mess around with all sorts of torque settings, your real root of the mess is the paper gasket. I bet, nobody with a M 14 has had any troubles there, no gasket , just an o-ring ...
