looking for a spark resistor also called a baffle for my muffler

like this one only one that works on a 150cc jainshe dirt bike

What it looks like

It looks like the one below but no stickers and better condition seat

How I got it running

So i got it unseased and put some oil in it and put some gas in it and I put on the gas tank and kicked it over a couple times and I got it to fire and I kicked it over a couple more times and it wouldn't fire so I got some starting fluid and kicked it once and it ran really high idk how to fix I'm working on it though (pics soon)

First looking at gas tank and inside

That's metal and a plastic piece from someone drilling out the locking cap and leaving it in the gas tank right when I got it it wouldn't EVEAN turn over so I put a crescent reach on the flywheel and got it freed up
