Excellent post, Mitch... thank you. I dare say you've just zeroed in on the cause of 90% of the burping/surging issues.
Mitch,
I've done what you explained on a Homelite 2-cycle weed eater and blower recently. Both were about a year old and would not idle. The carburetor was constructed so that it was not possible at adjust the low or high speed screw
unless you destroy the caps over the adjustment screws. While both of them work perfectly now, it really PO'ed me to have to do this.
Our EPA and CARB do not believe the owner of such equipment is capable of adjusting the float level nor low or high speed jetting. There preference is for us to take it to someone
certified to work on small engines and the preferred fix is to replace the carburetor. The part that is scary is that we have only seen the tip of the iceberg related to what the EPA wants to implement for small engines to lower emissions. It appears that a time will soon come where we simply cannot work on the engines - period. They will become disposable and incapable of rebuilding.
EPA also has a proposal (no hearing or rule making yet) that would make it against the law for any of us to change our engine oil at home.
Good job getting the low speed working correctly. It will be interesting to see how long he genny holds it's settings.
