Hi I have a 2 stroke 80cc motorized bike. I recently ordered a HP carb as I got fed up of the stock NT. After installing the HP carb the bike would not idle and stayed on full throttle so I adjusted the idle screw and it made a massive super loud hiss noise mean like a bus compressor oh and it sprayed me in black oil. I crapped myself n said oh no! Checked piston it looked fine checked clutch and adjusted it no probs there. Started it up and it idled but had a nasty squeak like a bird chirping. Revved it up and it didn't sound right I don't know what blew or what the HISS was but after starting it just made a very quiet tick noise on idle nothing like how it use to sound. I am still trying to figure out what has gone wrong is there anything damaged? where is the damage? Exhaust fine Piston fine gaskets in tack. Does my problem go deeper down? If anyone can shine a light on this very strange event then I am grateful.
