I believe they made the change a little after 1980. Maybe yours was built during the change over, or maybe it isn't the original engine. It could make a difference when buying parts.

Do you have points, or a pulsar coil?

idk coil is on the firewall going to assume pulsar

btw i did buy a new wire and plug gapped to .025 and didnt make any difference since the old one was well old lol

i had the screw out on top since it ran a lot better without it in and uploaded a new video of how its running now to my channel

Looks like you do not have a external starter genny. So I bet you have points under the flywheel cover. Did you have the flywheel off? First thing I would do is get a fresh set of points for it. They are a PIA to change and set with the motor in the cart. Check out this link. I tried to document doing the point change and setting in it.

I just watched the 4th video again. It most certainly has an external starter. The intake manifold has no hole for oil injection, so it's still pretty early.

correct external starter gen and i premix the gas definitely loosing power somewhere bought a cheep bicycle speedo and use to get up tp 19-20 mph (took a while) and now its topping out around 15ish

pulled it into the garage and jacked it up and yes the brakes are dragging yet again (again like the drums are warped) going to work on that tomorrow and hopefully get them straightened out any ideas besides new brakes lol
