Hello
@Nick Felt ...welcome to the
Oldminibikes.com forum.
Nice find for your first mini bike. We love us some Healds around here !
I've never seen a slide carburetor on a Heald, which leads me to ask about the governor.
Slide carburetors don't link to the governor, which can be a safety issue, unless you have a billet flywheel, and billet connecting rod, and have removed the governor's internal parts.
The reason being, the cast flywheels and connecting rods in these small engines will implode when revved higher rpms than what they are designed for. With no governor, over revving is too easy. Thus the need for billet flywheel, connecting rod, and removal of interior governor parts.
Does your hm-80 have billet flywheel and rod, and are the internal governor parts removed ?
