He we go. I was having problems with my DA 100 carb. Decided to buy a new one and rebuild the one that can on the engine. Got the new gasket set and rebuilt the old carb. Put it on and had the same problem, will not draw fuel. So, I took out the fuel tank to check it out, eveything looks fine. Checked out all the lines for leaks or cracks, they look fine. Took off old carb, swapped out control link stuff, put new carb on. New carb will not draw fuel either. I've been farting around with glow and gas engines for arond twenty years or so. I am baffled as to what he problem is ??
