ok man i had this problem about three times when i swappedout my tank for a keg. look on front of the carb if its the stock one im assuming. theres a ring and plate with 3 flathead bolts. take the air cleaner off so u can see insine the carb, then take the 3 bolts off the front, u might have to press in a bit to break them loose. be carfull and pull the ring off then plate( pull out just a hair and jet the gas drain out). ok this part is tricky. u look in u can see the float on a shaft, look on the shaft the first thing to slide off is a little sleeve on it. dont loose that, luckily i had an extra carb for parts. when u pull the float out theres a lil triangle needle directly above it, pay attention to how it comes out, set all these aside in order they come out. now clean the chamber out with a rag and carb cleaner. now u can see the jets in the back bottom. use a wide flathed and press in a lil to take out and dont strip the head these arnt cheap. pay atention to wich jet go were. now take a air blower and blow the 2 jet holes and jets out.(wear safety glasses that gass hurts realy bad when gets in ur eye). all in all ur just doin a minor carb tune up only about 15 min. but the jets are small and get dirt and or sand stuck in then some how but i did it a couple time because a dirty keg but it sounds like alot here, but when u do it its easy and worked for me just dont loose anything and lay it out so u can back track in order when puttin back together. hope this helps man....and howed the front end drop go?
