3.5hp briggs & stratton?

Hmm...
I'm assuming you bought it used, but the blower housing looks stock, so I donut know where they would be(I purposely wrote donut since I just ate one)
You might discover them when and if you start taking the engine apart.
Keep an eye out for those numbers, it will be much easier to find parts for your engine if you find them.
I know it was for me

And FYI to your earlier question, there are billet flywheels available for your engine.

Glad to know that the Predator disease hasn't taken everyone...
I don't doubt that they're nice engines, but personally, I'm all for Briggs and Stratton. Kinda hard to explain, kinda like how it's hard to explain why I like Fords so much...

I have a predator because it had more hp and had a gas tank also 5hp briggs are way more expensive in indiana and less common but i still love my briggs 3.5 more!

Yeah even here, the previous owner of my kart was contacted by people looking to buy the engine only. $60 for the frame and engine and everything! The original asking price was either $150 or $100. I bargained him down.
Also it's not hard to get 5 hp from your 3.5, and as a bonus it's probably smaller.
But in the end you could probably get the most power by having the most starting power.

Well my buddy rode my go kart (owner of the 4 wheeler) and i rode the mini bike for first time in a couple months but he loves my gokart lol

Karts are better, and safer for that matter.
Well, relatively...
