Ryobi / Honda only runs when choked
I was given a 205 Ryobi Pressure Washer by a neighbor. They told me they only ran it about 4-5 times and couldn't keep it running. So, this issue seems to have started long ago. First thing I did was drain old gas and pulled spark plug. The plug had heavy black (carbon?) build up. Assume due to running the engine with choke. Put starter fluid in cylinder, replaced plug and engine started. Drained and cleaned carb, then put in fresh gas. Would not start. Bought a new carb and installed. The engine now runs, but only when choked. Since it has a new carb, I assume the issue is a bad fuel/air mix??? if this sounds right, where might I check for the potential leak? Maybe a cracked hose? I replaced the fuel line, so it should not be the issue.
If I am on the wrong trail, anyone know what the issue might be?
