x1 bike tunning the Walbro WT-603 Carburetor any tips?

I just put together my x1 mini bike. i got the Walbro WT-603 Carburetor performance kit on it, but im curious if there is any tunning i need to do, since i see there are 2 screw for adjustment. i got the kit from scooterparts4less but there was no manual with the carb. the bike runs fine, but just curious what i can do with the carb.

pic attached of the carb

now the pic is attached

Just try and tune it. If it lightly hesitates, tune it leaner/richer until you get smooth acceleration and good top end.

Keep track of how lean you're running it, you don't wanna blow a piston.

Is the pic upside down? The primer bulb is supposed to be on the bottom lol
Someone else did it too, so don't feel bad.

WOW. this just shows how new I am to this. I'll flip it aroudn asap. You are right, this makes sense now. thats how the old one was installed. its been sitting my apt for 2 moths taken apart, so i guess i messed up on putting it togeher. would this damage anyting?

what about those 2 screws?

The carb is on right.
If it's running right why mess with those screws? I didn't see the adapter plate for that carb so did you mod the stock manifold for that carb?

I'm cofused. So i did install the carb correctly then? there was a plate that i put in there to attach to stock adapter. all monted nice and even. I guess I'll leave it as is then.

Now just need to get fuel filter.

Thanks

Hydro bike,

Just checked a chinese 603 (your carburetor) and a Walbro 603, you have it installed correctly. The pulse hole orientation is opposite the primer bulb on this carburetor.

Standard setting on the Walbro is 1.25 turns out on each of the screws or out a little more if you want to run it rich (safer, pollutes more). There is more than likely a tuning guide to this carburetor on this forum.

Yes there is just look to your left in the top 10 threads. How's to: HP carb tuning. Thanks to someone. Print it and keep it handy and by your side when tuning will make it pretty easy.
