How would I start older .028 wood boss that has no pressure relief valve?
In past I just removed spark plug, yanked a bit, then replaced it. No help this time.
Overcoming press could wreck the pull start and seems risky.

If harder to pull than previously....probably carbon on piston top and "head" (inside of jug top). You could try a tsp of fuel on the piston top to give it lube and then pull. Disassembly and clean carbon out is more permanent. If a flat spot exists on jug...could drill / tap a 10mm x 1.0 decomp valve.
