Tecumseh OHV125 203039B had no spark so I replaced coil. Runs now but surges and backfires. Occasionally while it is running a spark or two would come out from under the flywheel it seemed. Adjusted valves. Cleaned carb. Flywheel key looked fine but did not take flywheel off just the nut. What else could I look for?
