The accelorator pump on my thermoquad is bairly spraying out. The carb has been sitting for some time. At first it didnt spray at all. I removed what I think to be the needle valve under the nozzel where the fuel comes.It was stuck in there. I cleaned it up and now I get a LITTLE fuel.the car Idles ok but when you hat the accelorator it just hesitates.Any suggestions would be great.
