Servicing these tiny Walbro carbs tantamount to microsurgery, demanding completely different methods. Needing to go in deeper on these, I'm experiencing an ongoing learning curve.

250 carb circuits are gigantic in comparison. Some important circuit areas are hidden under blind plugs, careful removal/replacement required for access to these micro drillings.

Anyways...reinstall and start attempt on the Echo tomorrow. A pic or 2 of tiny components too.

Pic Walbro kit contents, intended for multiple applications. The larger 250 float valve vs tiny Walbro version (circled). These lack a float bowl....ports are used....setup done via pressure measurement .....specific diagnostic and special tools ordered, investment not a problem, will use going forward. Totally different ball game here.
