My Stock 78 Maxi has no acceleration. Not "I want to go faster or get a faster take off" but it barely moves and cannot make it up the smallest of hills. It bogs down and dies when riding in the grass by where I'm working on it. I just put all new gaskets in the carb (banjo, float and top), I've set the timing to full advance (only to trouble shoot my problem) and once I was sure it ran right I was going to adjust it much better, I've made sure the points are opening about the width of a piece of cardboard from a cereal box, and I put blue springs instead of the stock springs on my clutch. I've tried tuning the clutch every different way, counting turns having the screws out more, or in more and everywhere in between. Nothing has made a difference, or at least a significant one at all. So where could the problem lie?
Just want to get riding again,
All help is much appreciated.
