Leaf Blowers

1 yr old H 125b blower. was happy with it, so bought a walk behind H mower also. Started up the 125b and it wouldn't run properly, even on choke. Took apart the carb, cleaned all ports, re-installed, then only ran on full choke, and not well. Adjusted the carb by dremmeling slots into the stupid EPA conforming screws. Ran slightly better after mild adjustments. Now won't start. Starter cord, spark, fuel is all OK. Now there is grease leaking from the bottom of the housing. air purge is also not re-filling properly. Unit now will not start. Plus, warranty dealer is not convenient (25 miles away)

Any ideas or just toss it and go back to Stihl?
