Hello everyone

If it starts good, runs good and doesn't foul plugs I would just run it!

starts really good most of the time i dont even have to choke it starts right up idle is a little ragged when it first starts but thats about it. Do you think that if i decarb it, it would help it because it has been sitting about 3 years. Thanks Trip

The de-carb may raise the compression and clean out any old carbon.
