I have an old mac 10 that has not been used in years. It is probably from the late 60s or early 70s. I thought that it would be good if the old boy could run. The carb was rebuilt, new gas line and filter, new spark plug and fresh fuel.
The saw will now start and run. The carb has a low and high speed adjustments. When first started the saw runs really great with good response. After it runs for a few minutes the response is not good and finally stops. I thought that there might be a problem with the gas cap vent but when i opened it up that did not help, the saw was running then.
Does anyone have any suggestion what could be the problem. Thanks
