sounds good now ! wouldn't go pulling the engine down , your visual inspection through exhaust sounds promising , just block decomp hole and make sure you have the two resistances.
those old 125cc normally run well after a points and carb clean.
as far as the loose decomp top , not uncommon and normally doesn't affect the operation
cheers tomo
