Just look at what people run on other 200ish CC engines.
That's what I'm trying to figure out but I'm new to this stuff.

So far I've thought about using a 200ish cc carb and know I need a manual choke and throttle on it.
Ebay, you'll find a good used one there much cheaper than the new ones at parts places. Tecumseh is out of business so the prices for the discontinued stuff has skyrocketed. I quoted a guy $120 for a carb setup for a Tec just a few weeks ago.. rediculous
I found a new one for around $70ish online but since I see people complaining about tec carbs I was trying to figure what would work and maybe cheaper.
I found an old dirt bike yesterday. It looks like a clone of a honda E22 beginner bike. It's got a good amount of parts still on it. Luckily it still had the carb and it's a dekni zp19. I tried putting it on my OH195 and it fits. It's dirty on the outside but looking at the throttle plate, it's clean and when I shake it I can hear the float moving. I haven't taken it apart yet. I was planning on trying to see if I could get my oh195 to run with it, any thoughts?
Here's some pics of my engine:
How I bought it:
Removed air filter:
Looks like the DEKNI PZ19 carb fits:
I'll go clean it in the meantime. Thanks everyone for your input.
