Yes, My question is what part of the carburetor is defective that would cause it to be constantly out of adjustment? It's a homelite super 2. I have a carb. kit on order and I think it's the diaphragm. I have had the old one out but it looks good, only a little stiff. I have adjusted it(running good) picked it up and before I could start to cut it was out of adjustment? I do have another question that may shed a little light on this, the gas tank cap had a bulb on it but it cracked in a million pieces. Will this affect the carb. adjustment? I tried to order a new one but the shop owner said it was no longer available. How about a leaky gasket? Seems like through the years I've had this happen before and never fully understood just what caused this? Any help would be appreciated.
