its a 2 stroke engine form 1972 i think lol. The fuel is a couple months old but seems to be in nice running condition. I finaly got the high end needle fixed up and it screamed at full throttle but then died or didnt run for long at all on idle...[&:]. just my luck haha. now i think my glow driver is dead so il recharge it then try to get a perfect idle and only then work on the high speed. Oh and one question, i have to small screws on the side of my carb. One kinda on the top and one on the side right next to the throttle arm. not in it or on it but next to it. Is that normall? the engine has never been complicated before and now i think il have to reset all the needles from zero..sigh..
