Yeah, me too... The original SG and VR are still running on my 129 - I've replaced two batteries and one set of brushes since '85. I've had to whack the VR twice when it hung a set of contacts closed (SG kept rolling when I shut the engine off). Worst problem I've had was extremely high charge, caused by loose ground wire on the battery to sheet metal strap.(start with the obvious, I found the loose ground AFTER getting the VR loose, which is a chore on a WF)..
The SG has about 1200 hours between the original engine and the replacement I put in in '95. (I sold the original engine to a friend, he was going to put new rings in and put it on his 110 - I talked to him a year ago, he said he never rebuilt it, just put it on as was, had more power than the 10 horse did new....). I figure the SG doesn't owe me anything after 1200 hours....
