Guys, I need help 
After building my 72cc with all of those mods that I wrote, I got a first problem, and it's a biggie...
I was riding home from my GF, the scoot went like crazy...at one moment, it changed sound and stopped pulling (like it was overheating, but it wasn't), there was no WOOOOT sound from the air filter and it went like a 49cc...
The morning after, I start it, same thing. Then I clean out the carburetor...I got my speed back but two or three new problems.
First, it won't idle. I got the idle by 20% up, it just works for a few seconds then dies with a "SPOOOSH" from the air filter. Irregular, like it's knocking.
Second, when I let go off the throttle, it stays on for a second more (like I'm letting go slowly)...annoying.
Third, the sound from the exhaust is different. Especially when I let go of the throttle from WOT. The sound is gargling, like it wants to fire off but it can't (because of the stock exhaust).
I thought that the mixture screw got moved somehow, but it didn't. Tried setting the mixture before 10 minutes, didn't help.
It's the same if it's hot or cold, no difference at all.
Any ideas??
