Answer
Hi Bear Wheeler,

Check the air cleaner for fuel/oil contamination. Drain airbox drain tubes of fuel/oil. See if that improves performance. Remove the spark plug(s) and inspect. Clean plugs and reinstall. Check these and we'll resume from here.

It would be helpful to know if the engine starts, idles, and accelerates. A more thorough description is needed to accurately diagnose the symptoms. Please separate sentences with periods. Its difficult to read the description as written.

Respectfully,
