Since I installed the rebuild engine on my tomos I havent taken it out much but when I did i noticed a slight stutter under throttle and I was convinced it was a problem with my stator which was the only old thing I used on my rebuilt engine. Now recently I upgraded Sinclairios bike to HPI and he said I could use his almost new points stator on my tomos. The only thing I wanted to keep was my 12volt lighting coil. I swapped that onto his stator and installed it on the tomos and set the timing. It fired up first kick but I will have to wait for a dry day to see if this has solved the problem.
New stator is on the left.
