I just installed a used VH4d in a manlift. Before I got it, it had been sitting for years, but it started easily, ran smoothly, didn't smoke, seemed to have all the power it needed. I used it for about half an hour, then shut it down.
A month later, it wouldn't start. It fires, but won't catch. There aren't many things that could go wrong just parked. (e.g. if the timing was right before, it can't be wrong now) It has spark (it's a magneto ignition version). The float bowl fills with fuel. There's no fuel dripping from the carburetor. The plugs were a little sooty, but not wet. (I cleaned them anyway) They are in new condition. The obvious answer is that a speck of dirt got into the carb, but I dismantled it and it's immaculate inside. All passages are clear. It fires on starting fluid, but no better than on gasoline.
What is there left to try?
