hi yes i tryed the checked for intake leak. this is a singel speed trany.i rebuild this to improve pull on hills.same problem then so i thougth if i rebuild it this wood fix no pull on hills i just got finished decarbon muffler pulls good with out muffler on.decarbon did nothing to help this problem.i sanded points with 400 grit.have blue spark at plug. could the clip be in the wrong place? its on the top now. and i have tryed all slots. it runs best with 62 jet is there a standard for this elevation? i guess i will change the points if you think this will help like i said it goes good with no muffler on. larry
