well i have a 80cc/66cc motor kit in my bike which i just replaced the head with the slant head, cns carburetor and a sbp expansion chamber
now when i tuned the carb i let it idle for about 4 or 5 min to let the motor warm up i then pulled the plug and gave it a quick clean so that when i tune the motor its warm and doesn't have a fouled plug
i set the air/fuel and then the idle and run it for a few minutes and it sounded great revved nice and i pulled the plug a nice colour no real build up of oil on it i go to take it for a spin loads of power but a few minutes into the run it start to loose almost all power it will idle but it seems as though as soon as i go to give it full throttle at about half throttle it just makes a lot of intake noise and doesn't continue to rev like its being held back i pull the plug still a nice colour i am running 32-1 for my mix on 91 octane i pulled off the filter and that didn't help i checked my petcock filter clear and my inline filter is clear i can't find any place for a intake leak i have no idea what to do ill post a video up later on this morning of it thanks
