My MF 135 Gas has been running well until recently and I cannot solve issue. It sputters through exaust with lack of power. It was last rebuilt 20 yrs ago and receives about an hour a week. The compression is 130-135-135-140. When I brought it into the shop to fix I replaced the distributor because it was an unidentifiable aftermarket and I wanted a Delco type to convert to EI sometime in the future. This made no difference in performance. The carb was removed, cleaned and a kit installed and this made no difference either. The timing is set at 6 deg. static. My assumption at this point is exaust valves but before I tear down I wanted to put it by the experts. I am getting a strong spark at plugs.
Thanks
