1970s Sears Free Spirit 8088 Moped NEED PARTS

I am trying to fix a 1970s Sears Free Spirit 8088 Moped and it is running and whatnot, but its bogging down on full throttle and not wanting to go good without the choke on, I am thinking about replacing the jets, but I dont knwo where to get them from. Any ideas? Would there be any other names this scooter would be sold under?

Thanks

Probably just a clogged main jet. Clean out the carb. No need to replace the jets.

Well I have cleaned out everything on it. Anything that contained gas now contains dust, but I have since cleaned everything out and replaced the fuel line and filter.

I kinda figured that was the only thing that may be an issue, maybe corrorision on the jet (which it has some) has caused it to allow less gas through.

Needing the choke indicates a lean mixture. If the main jet is clean I'd suspect an air leak, possibly leaking main seals. Jets don't go bad and don't need to be replaced unless changes such as porting, exhaust, etc., are made to the engine.

The main seals are the ones that seal the crankshaft main bearings. Rubber seals eventually harden and allow air to be sucked into the crankcase leaning the mixture.
