When you lose an eclip

Ok i dont understand exactly what you mean on mine i dont have that.fitting  i know one goes from that vacuum fitting to the carb and.the right on goes to the petcock on the left side of the scooter just under the tail frame  mayne mine is a little different i will get a picture of where the right hose leads to give you a better idea asap « Last Edit: December 22, 2010, 12:47:33 PM by havoc983 » Logged

this is where the right hose is connected to if this helps any at all Logged

You should get a longer tube for the carb so it's not kinked up and see what happens. I have a feeling that it might cure your issue. It can't hurt and it's cheap. « Last Edit: December 22, 2010, 04:42:20 PM by Fox » Logged 2005 JMStar Sport 50 4T 2003 Qianjiang 50 2T If you are in the greater Los Angeles area and need a good, reasonably priced scooter mechanic, send me an e-mail or an IM

i am not fully certain but i believe it is a vacuum leak no more than ever i did swap the hose you pointed out with a longer hose but the problem is still present i also swapped out the old fuel filter for a new one the old one was yellow and clogged i think so to be safe i swapped it out i then test the carb by running with no air box and placed my hand on the backside of the carb i was able to rev the scooter and felt gas against my hand as the diaphragm rising up to let the main jet work so i know the carb works i just dont know where to trace the leak as far as vacuum leaks go i checked the air box over but saw nothing other than the hose that connects from carb to it was off i placed it on and tried again but still no luck it dies with throttle every time except for when i put my hand to the back the carb maybe this info will narrow the problem down for you

When i took apart my carb i saw no clip on the diaphragm needle any other suggestions i did readjust air /fuel mix on carb thru the scree on the side so any other possible ideas? I know fuel is not an issue i believe it is vacuum but where do i start vecause when i.put my hand against it it throttles just fine for a while til i remove my hand or if i leave my hand to long woth out opening the throttle all thw way it will die and not rev

I've never seen a 150 that had no clip. Look again. Two screws and the carb cap comes off. It'll take less than 5 minutes. You can do it through the seat tub hatch on most scooters. If you find a clip, move the clip to the top notch and try it. If you find no clip then tell me what's in it's place.

Silly question, but do you have both nuts on the intake manifold, because it doesn't look like it in the 2nd pic you posted.

Yes iys there pics taken while dismantling scooter use one to hold in place while taking pics Fox will check later about click and notify u of my findings as well

found the notches you were talking about fox and saw my clip is gone is there any suitable rigging i may do to fix this or would i have to order another clip setup online? i was think i maybe able to buy something to fit onto it and that would fix it temporarily or permanently just a hope anyway but the clip is gone i cant find it anywhere in the carb or diaphragm

AHAH! No clip!  Well now, we've finally found the problem. The needle is supposed to rise with the diaphragm when you open the throttle allowing more and more fuel into the engine through the main jet the higher it rises but with no clip then it just sits there so you get idle but no throttle. The idle is a separate jet.  You can get a tiny washer and cut one side of it and pop it on there maybe or, you can put a little glob of 5 minute epoxy on the end of the needle and then install it after it hardens. As long as the glob is bigger than the hole in the diaphragm it'll work as a temporary fix. What city are you in? Maybe there's a shop near you that has a clip. If you can't get a clip locally, PM me your address and I'll send you a clip for nothing. I'm 99% sure I have one. BTW: If there ever was a clip it's either been lost during the carb cleaning, it's in the exhaust pipe or it got blown out of the pipe and is lost.

pensacola i will look around here after work tomorrow and see if i can find something maybe at home depot or auto zone/parts stores and see if i can find something suitable till i order the piece if necessary

This link is to a hobby shop in Pensacola that stocks parts for RC cars that use small c-clips. They have a assortment pack for $2 http://www.hobbytown.com/Shop/hardware-screws-nuts-bolts/e-clips-c-rings-universal 2620 Creighton Rd., Suite 302, Pensacola (850) 476-2708

just wanted to say ty fox for all the help the problem was solved by the clips from hobbytown like you said and it works better than ever now i guess since getting here i gave it a massive tuneup so it idles great revs perfect and has great acceleration and a top speed of 80mph so ty very much and merry xmas to ya

NICE!    I love it when I help fix a scooter thousands of miles away.   I think your speedometer is off or it reads kilometers per hour. There's no stock 150cc that can go over 60-65mph downhill with a tailwind and the rider leaning forward. 50-55 on flat ground sitting up is normal. You can play with the clip positions to achieve the proper plug color. Nutty brown with a hint of Grey is ideal. Lower the clip to darken the plug (More fuel) Raise it to lighten the plug. Merry Holidays! and Happy New Year!    this was one issue that i had and a guy off of scooterforumonline.com walked me through the issue i had lost my eclip on the carb needle the scooter would start and idle but not function properly when giving throttle as the eclip controls the rise and fall of the needle in the carbs diaphragm
