bad Throttle Problem

so i have had my stinger 66cc for a few months now i use it every day its roughly about 600 km on engine now i recently bought a speedy carb the red one it worked great for the past month i added a shiftkit it was still working good but i had to modify the top the red plastic on the carb filter cover it fell off eventually still rode fine home i lost it on my way home... i changed and put in a new derailer for the bike and tried to use it again now it doesnt want to run properly at 1st it was like i can get it up to about 20km\h then it would just bog n sit at that speed now it will start up but wont stay started unless its choke is turned on then it runs like its full throttle without touching the throttle and if u turn off the choke its almost like it floods it im kinda thinking the float but its doing the same thing on both my carbs?? so i dunno thinking its something else not the carb but i dont know what

I'm wondering if you sucked a piece of the broken filter into the engine - maybe caused a seal to leak or bearing to bind.

the engine still runs fine its just like the throttle is stuck on full the entire filter cover fell off and was only 2 weeks old so i doubt any of the filter was coming apart it was the screws came lose and it came out on the ride home its throttle or carb related im thinking the engine still sounds and runs fine other then the gas problem

hello was a air leak the carb was getting air in through the intake section the engine was raised a bit from the shiftkit i had installed and i guess put the cartborator out of alignment by a couple mm
