echo SRM 210 string weedeater

[lazymjs]

I have a echo SRM 210 weedeater that starts but will not run. I have performed the following: Fueled with commercial 50;1, Replaced the air cleaner, Replaced the Spark plug, carburator, muffler and all fuel lines. checked engine port for carbon buildup. No improvement, am at a loss for what else to check or due. Recommendations please.

Checked for junk in the tank?

Yes, flushed several times with commercial 50:1

OFF-ON switch or wiring intermittent short?

Spark at the plug electrodes?

I checked spark..appears to be adequate. Did not think of intermittent switch wire, will try to check on that tomorrow. Appreciate it.

More I think about the switch, it starts every time, would that happen with an intermittent wire?

Don't forget to check the vent tube.

Natural position may be OK but running vibration may make it touch something. Just another thing to check.

Does it start, then die immediately, or will it run a bit with choke on, then die with choke off?

With fuel line off carb, will fuel flow freely? Thinking of a plugged hose nipple on tank.

Reversed fuel lines into carb when re assembled ?

Reversed fuel lines could be a possibility, when I replaced carburator I had no picture showing me how they should be connected. I have the white round tube in the housing cavity for it on the right, then the black tube to the center and the orange tube on the left. I thought that was how they came off (to the best of my 80 year old memory);
