i inherited this bike from my grandfather. it had sat in a shed since i was a kid. before that it sat in a shed since my dad and his siblings were kids.
i rebuilt the carburetor. i don't think this is the problem. when it starts it runs like a champ, never smokes, and never stalls.
the engine itself doesn't make any bad noises, and feels about how i would expect 7hp to feel.
the one known problem is that there's something wrong with first gear. it clatters badly, and i'm compelled to get out of it as soon as possible and/or not use it at all. consequently, i usually just take my time and roll off in second gear.
when i first started toying with it a few months back, it would start pretty easily. the last few weeks it's been harder to start. it's the same feeling as when there's no compression. though i doubt that's the case. i came to find that i could sit at the top of my steep driveway and as i roll about halfway down i could throw it into gear and away i go. this morning that method got me to work, but now i'm stuck there and can't get home:(.
the battery is new and the lights are bright. i checked the plug and it looks very good, but there's no spark. i pulled the cover off the points, and the look okay, but nothing is moving there when i kick or roll the bike. does that point to some kind of clutch problem? i wonder if maybe the engine itself isn't turning over at all.
