HELP.....bike is running terrible!!

ive just bought a pb off ebay ive had it 4 like a week and it was running really well..but it didnt idle at all except for the first time i would start it up before using it.

i played around with what i thort was the idle screw on the carby and got it idling..but now the bike isnt working properly at all!!

The bike now hesitates and when getting up to speed starts to sort of "bunny hopp" and looses power and then completly cuts out..im not sure if its a fuel problem or what, but im confused..

Please Help!!

it sounds like you have a fuel issue problem. what you must do is the following; remove your total fuel line from tank to carby including fuel filter and toss this in the bin. remove the carby from the engine and clean out all internal areas . when the carby is spotlessly cleaned out you then can re fit this plus re fit new good quality fuel line hose plus a good filter and also a nice new ngk- bm7a sparkplug. this is a common problem with the cheaper type p / bikes so when this is all done your bike will be reliable, just like the lawn mower is.

well i had the same problem but i didnt touch no screws on my carby i just had a flat so yeh lol i just relized about 5 mins ago!

so gonna go pump up then see if it is the tire.. but the thing is i put it on stand start it up rev 3/4 and runs fine if i go 4/4 still fine so probily the tire!

if its pretty new its not the springs, if your worried about the clutch, get 10 turns or a 2 shoe adjustable
