For those considering AeroSport...

[Jim P]

I have an AeroSport IO-360-M1 (180 HP, injected) and after about 450 hours, I had indications of a small induction leak on #3. Sure enough, there was a couple drops of oil in the bottom of the sump intake flange (pipes are inserted into sump). I called Sue on Monday to get the part numbers for new gaskets, and she offered to just send me the lower o-ring and upper cyl. head gasket - no charge. They covered UPS and two days later, parts are on my doorstep! So for those considering buying an engine from Bart, you can't go wrong; even 6 years later, they're still providing great support for their products.
