I searched, and did not find the same problems that i am having. 25 Horizontal on a Lazer. 1900 hours. Problem began on rouch ground. Engine surged and finally floaded out. Cleaned plugs and got it back on the trailer. Changed plugs, fuel filter, air filter, needle and tagged out the two jets on top of carb. Motor runs, but still very rich and only about 3300 rpm at full. What else should I look at?
