OK I went to utube and watched the rebuild and cleaning videos. I should have done that first. I found how to put that lever and spring back in without destroying it. I am going to get some carb cleaner and remove the needles and spray through all the holes. I have several old carbs that I got off ebay for practically nothing. I will take the lever out of one of those and try again with it installed.
In reading the Walbro manual I was surprised to learn that the screen has more purpose than catching debris.I will have to replace it.
The dirt got into the screen ared quitsa because I unfortunately installed the external fuel filter backwards after it fell off. It dumped all the debris it had caught back into the fue
update:
I thoroughly cleaned the carb and still no joy.
Its the same as yesterday choke it and it runs a short burst an quits.
I give up. I have other toys to play with
