[QUOTE="wsurf4me, post: 155024, member: 9937"] Went thru everything this weekend, carb looked good the emulsion tube orifices were all clean. It still wouldn't start, the spark seemed weak to me so I checked the points next. The gap was way too small, maybe 0.008" at best. The phenolic block was badly worn, the cam looks ok. I replaced the points, gapped at 0.016", put it back together and after quite a few kicks it started up. Runs much better, no cutting out although the idle seems a little rough - adjusting the idle mixture screw didn't seem to smooth it out . So overall I'm getting close to where I'm happy with it, however I found a couple of other minor problems. First is there is a very, very small gas leak at the carb, it appears to be where the brass hose barb is pressed into the aluminum carb body - any suggestions on how to fix this? Also I have a small oil leak at the head gasket, I assume the only way to fix this is to replace the gasket, not sure if it's worth it at this point. I will start by checking the torque on the head bolts. Finally the rough idle, not a deal breaker but it would be nice if it was a little smoother, could this be related to the 0.016" point gap?
