Hey guys, I have a 1980 superglide shovel. The other day I went to wake it from its winter slumber but the battery was dead. No big deal I figured so I went to kick it over. found TDC compression stroke went for a big ol kick and slip scrape my leg was at the bottom. It felt like it was half engaged or something. tried it a few more times and every couple or three kicks it would do that. Any ideas?
