In regards to my last post on the filter, I sprayed the filter with several different kinds of cleaners and used a tooth brush to try and clean the filter. This did not help my main problem: the 028WB starts on no more than 3 pulls usually 1st or 2nd. After running about 5 min. it will start missing out until it simply quits. I can choke it and still does not change the miss rate unless I continue to choke it then it quits. I let it idle and it still misses until it quits. After it cools down for a few min. it starts great again, only to start missing until it quits. In your opinion is it electrical, points breaking down,condenser or coil? Rebuilt carb and no change. How much trouble is it to change ignition over or stay with points and coil? Appreciate any assistance you may provide.
