we got a small hose and put it on and it still sounded muffeled and backfired alot..but it wasnt on there good...would this make it run wierd like that.?and thanks for the speedy responce guys
 
it all started when he used my dirtbike gas..i mix it 50.1..he had les than a quarter of his normal 32.1 mix and then put in like a quarter of my 50.1..after like ten minuts of riding it started running crappy.but we did drain all the gas from the tank and carb.and he put in a freash mix and still runs like hell.
 
hey i dont mean to jack your thread, but freek... i hear guys sayong to do a leakdown test. what exactly is that?
