ok im lost. putting scoot back together and calling it a night as its 10pm here and very very cold. took the second washer out so that its back down to 1. nomatter what i set the air/fuel mixture on the carb, the thing still hesitates/sputters around 6-7k very bad. im not sure if a new spark plug will remedy this but i thinking it might just be the muffler being toast. i dont know what else to try to get that sputter to go away. so should i take this muffler apart, repack it and re rivet? or should i just get a brand spankin new one and save the hassle? cost to fix this muffler is about 25-45$, cost to get a cheap new stainless steel muffler about 100-250$ ( thats shipping included i know there are mufflers that cost more then 250$ but im not about to get one of those lol ) gnite =)

yeah it is fairly easy, i did have to take a piece of frame out of the way, luckily it unbolts. its the tube piece that holds the front mounts for the bigger under seat storage container. ive seen some that are welded in place =( like i said im glad i was able to unbolt mine to get to the top of the carb. posting back with results after the second washer is added.

so i tried it with 1 washer it took all of the sputter out of 6k rpm, very beautiful. but then it moved it to 7k rpm lol. im going to fashion another spacer and put a second one in there, after that i will adjust the pin on the side of the carb to get the proper fuel air ratio as im sure moving the slider a few notches will mess that up.

hope it does too, i have a feeling that i will be adjusting the air mix ratio after i add a washer to this do you think i should use 2 washers instead of just one? or try 1 and see what happens?

had to go digging for about 20 mins in my tools but i just found a few washers. dinner time then back 2 putting carb together. maybe if i get it richer it might cut down on the heat in muffler? i think its still toast lol. its that loud new by the way its just the recording quality of my phone sucks makes things seem different then they are. thanks for the idea alley, will post back with results after dinner =)

clip and needle? i assume i also will have to cut the fuel flow for this? as im sure it will make a mess lol. i will get right on it, never have tried that before but going to give it a go, its getting dark so i hope i nip it in the butt before its dark. yeah the hesitation around 6k is horrible stuttering and popping, come to think of it, i had that mixture pin almost all the way out earlier and it didnt change a thing, so maybe it does need that clip moved to allow more flow. this all tells me that the pin on the carb im turning is for air flow and not fuel flow just to mix it properly.
