If not fixed it will get real ugly X(. Best to do a leakdown test. Check that the throttle cable is working butter smooth. Clamp tight on carb :both sides? Oil injection hose on or nipple on if blocked off? Can you see any cracks in the carb to engine boot? Is carb cap on tight? You can do a leak test on carb area. While running either spray with carb clean, start fluid, or wave an unlit propane tourch slowly around all areas, it will slow down if it's pulling the extera fuel in. Next completely clean carb paying close attention to pilotjet and circut. If that fails then you need to do the L D to find where it's leaking. B)

Agree with Larry only one way to know for sure, do a leak test on it. If ya don't have a tester, Pm me I ship overseas. below is the instructions. While ya have the carb off dissasemble it clean it spotless, check float adjustment before reassembly!
MOST COMMON PLACE FOR AIRLEAK IS THE INTAKE!
