seems I've inadvertently joined the skyhawk club
had a customer come in that had screwed up his top end - he only had the thing for maybe 3 months
he didn't bring old parts in, so I sold him a standard barrel & piston set off the shelf, but he was back next day saying it didn't fit
got his old parts in and they were a high-wristed piston set
I opened up a new motor, and it was high-wristed. Not sure when my supplier changed over, but now all my standard repair parts aren't gonna fit my motors.
Now, I have to order a bunch of skyhawk repair parts & be careful to measure things to see if anything else is diff now : (
Sometimes I sets and thinks, sometimes I jes sets.
