Iam going to sound like a noob here but according to a diagram i saw in my clymers service manual my 89 blaster has something called jet needle washers which I have never seen till I owned this blaster. Is it supposed to have one or two and does one go on top and one under the e clip? Also it's missing them I ordered some of what I think is right but idk I'll give an Ebay screenshot. Any advise is appreciated also this blaster is stock as stock gets other than oil injection delete but for some reason someone put in a 240 main jet which is incorrect I do not have any idea as to why from what I read it's supposed to be a 220 jet on the 2nd groove my vitos carb kit comes with a 230 jet can I just put that in and set it to the 2nd groove?
