I agree with Tom Z. These motors are excellent, but they need to be in tune for them to run well. The low pressure fuel pumps are common service items. One sneeze from the engine and they rupture. Best way to prevent sneeze is to make sure everything is right. I would also perform link and sync. Very easy to do. You can find a pdf OEM service manual on FeeBay for less than $20.

Learn how to do routine maintenance and this motor will treat you right. I have over 600 hours on mine, but it has taken some work to get there.
