I've checked the carb, it is clean in the hole where the needle goes. The needle is fine, not scorched. The spring is also fine.
When I reseat the needle carefully, it is fine. But when I press the throttle too much, it seems to be stuck outside of the hole.
It worked for many years, but last week the machine accelerated suddenly when I pushed the throttle too much and stayed fully on. I quickly avoided diaaster by turning the key off.
I thought first the throttle cable was bad, so I replaced it. But it is the same even with new cable.
Any ideas?
