Last week my Bug started getting harder to ... start. It starts fine in the morning, and after a long day at work. But if I shut it off, and try to start it right back up, it's a little tough to get going. The engine rolls quickly, but without a spark. It seems if I give it a little gas, she will get going again, and irons out the stuttering.
It feels to me like she is getting too much gas (flooded a bit). And it also seems I am not getting as good gas mileage as I had been in previous weeks.
Is this a carb problem? I have been through Muirs book a few times to investigate, but his raps on carbs are all pretty short.
I also fiddled with the carb looking for anything "strange". I noticed if I play with the 'idle adjusting screw' (pull it pack), the idle cam level doesn't spring back with much 'umph'. The spring action seems a little tired out. But then again, maybe it's not supposed to be very springy. Kind of like a 'kung fu' action figure that spent a few years in the sand box.
I have read this same complaint many times (bad economy, hard to start) but I don't think that their problems/solutions apply to what I am working with.
Also, the bug is a 68' (rebuilt stock) with a single carb' on it.
