I Give Up

[Kurt in NJ]

when you have the problem take the drain plug out under the main jet and see if you have continuous fuel flow— have a container,wrench etc all ready and before you go remove the drain plug so you know you can remove it and replace it without problem and you would know what no problem flow looks like.
a clear container is best because you should also let the fuel settle a while and then look to see if there are 2 layers because the fuel is bad.
