I finally got around to getting a saw carb hooked up to my bike. The problem is that it doesn't run right, and I can't make heads or tails of anything. First of all, it's hard to start or doesn't like starting at all. I turn the choke on for a few seconds, turn it off and it starts. However, it doesn't like to stay running, and if it does it idles very high (4-5k rpm). Now in my opinion this seems like it doesn't have enough fuel or has an air leak. Judging by the spark plug and the amount of smoke coming out of the exhaust, it says it's rich. After idling for a while it dies again, and is hard to start. If I give it throttle it just dies, again seeming like it needs more fuel, but I can get it to rev up sometimes when it's just sitting and I've never seen so much smoke come out of it before. If I actually try to ride it, it dies with throttle.
This is the carb I purchased: https://www.amazon.com/dp/B08MQCVX2Q?psc=1&ref=ppx_yo2_dt_b_product_details
I have the fuel line hooked up to the bigger of the two ports, I assume this is correct because I don't think it would run otherwise.
The two screws which I'm assuming are the fuel or air adjustments make some difference but at this point I don't even know which one is the high and low speed adjustment, or which way to screw them to make it leaner/richer, that's how little sense it makes.
It's 40f out, I'm sweating, and my legs are tired from pedaling the thing so much trying to getting this stupid thing to run right. I've never messed with these carbs before so I don't know if I'm doing something wrong or what. @Karl Snarl please save me.
