if it wasn't jetted right, It won't run at all. I would find a jetting chart and go from there.

Look into a TEMPA FLOW or ATACC system.

This will keep your jetting spot on for temps, the 440's need to be jetted right to run well.

Don't hold it to the bar for extended periods of time.

It probably needs to be replaced. It's cheap.
