I am the 8th owner of this fine piece of machinery. I cannot seem to get ahold of the most recent owners, although 4 POs are registered here. I think the engine is pretty sound. I am having an issue with the 3 pin connector for one of the coils, every now and then the engine misfires and I have to get out and wiggle the connector on that coil to get it to fire again. I'll be looking into it a bit further after work today. I think it's just a connectivity issue. I did get a carfax showing all preventative maintenance and service records. They were done regularly up til the time I bought it. Also, as I mentioned previously, the third owner replaced the engine with a rebuild at around 60k, so the rebuilt engine has around 66k on it.
