Cleaned carb, now its slower

I cleaned the stock 12 bing on my maxi and now it is slower. When I give it full throttle, it seems to lose power or hold back from what it used to be. Before I could bury the needle at 30 and now it will not even make it to 30. Any ideas?

clean it again and make sure it is back together tightly. You may have gummed it up again after you cleaned it.

Don't suck at putting the carb back together? Na I'm kidding sometimes when you clean a carb you don't get everything out you only loosen it up so the gas will move it to somewhere less convent for ya. Or you could be sucking up nasty stuff from the tank. May want to just clean the whole damn fuel system.

Re: Cleaned carb, now its slower

How is this a Performance Tuning question?

I didn't change the needle setting but did lightly put something in the jet. After that I cleaned it with carb cleaner.

I cleaned it again and it is still the same. Could it be the fuel filter I bought at discount auto parts which was probably meant for a lawn mower. It is not clear and there was a bunch of junk in the carb when I cleaned it the second time. Thanks

Re: Cleaned carb, now its slower

Did you clean your air filter? Changes are your carb and airfilter were both gross. You cleaned the carb and now it's getting more gas, but your air filter element is all rusty and gnarly...

If it's a maxi, those airboxes are hinged and snap, but they seal them. You can run a blade around the edge to cut the seal, pop it open and then either replace or clean your air filter element...

That's it... where the old one? Clean it..

Re: Cleaned carb, now its slower

Wait, I thought you typed air filter... It's early and i'm not awake yet.

It's not the fuel filter. Those either work or don't. Do what I posted about the air filter...

Re: Cleaned carb, now its slower

Look in the gas tank, see if it looks like shit in there or there is a bunch of rust, rusty crap coming down the line can plug several different places/things up along the way, you may have several places to clean.

Mostly check to MAKE SURE you didn't leave leaky spots anywhere when you took your carb apart and reassembled it. Intakes are famous for leaking and so will carb top covers. get your bike idling and spray carb cleaner in tiny spurts at the carb and cylinder where surfaces meet. (close up as to not suck any back in the air filter). If the bike kills or lags or runs faster or whatever, different, the carb/joint leaks.
