Hello everyone, I need your help. I spent the whole afternoon trying to fix my blower, It has not been running right for a long time. Here are the symptoms: 1. only runs at a reasonable rpm at HALF CHOKE. 2. If not at half choke, the engine will bog down and die. 3. After warming up (for 15-20 min) it needs slightly less choke, but still needs some choke. Whats going on? Any suggestions? Here is what I did to try to repair the issue: 1. Replaced all intake gaskets 2. cleaned carburetor 3. replaced spark arrestor screen and gaskets. 4. replaced and gaped spark plug 5. replaced all fuel lines and the fuel filter 6. replaced air filter The carb has NO adjustments so I was not able to fiddle with anything. Today I also noticed that for the past two years I have been using a 40:1 ratio oil. I thought that was what it required and I felt pretty dumb today when I found out it actually uses 50:1 so I swapped out the old fuel also. This was all to no avail. It is still broke. Help!
