I was given a 1982 Honda urban express nu 50 and i got it running after cleaning the carberator then I rode it for a wile and it was slow found out the belt was shredded so i got a new one that fixed that problem but now it will go fine putting around the yard but when I open it up on the road its very boggy and wont get wound up. I have cleaned that carberator 4 or 5 times now in my ultrasonic cleaner,carb cleaner,and compressed air still aint right I dont know what to do next ANY suggestions greatly appreciated.
