Answer
 Hello Tim:

 From your Description it Sounds like the Main Carburator Jet is Restricted with the Varnish that Gas Forms Over time. Using the Choke, can you make the Engine Try to Run at Full Throttle? I Suggest the Carburator be Cleaned and Rebuilt. Disassemle and Soak the Carburator Overnight and Blow Out All the Passages with Compressed Air. Install New Rebuild Kit. Send me the Model Numbers Off of the Engine, Please. With these Numbers I can Locate a Breakdown for you to View Online. Hope this Helps. I am here to help if you Require more Assistance. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully

 John
