Hello
I have a walbro carb from a weedeater featherlite clogged with dirt, hairs, rubberish deposits on the inner filter, small circular screen inside.
If I remove all covers and needle valve , can I flush with thinners ?
Is sure? Or it have other rubber parts inside I can damage.
In my country I have no many options.
I know the circular screen can be removed and changed but I have no spare parts.
In the needle valve side have a metal plate with 2 philips screws, can I remove it? It help ?, one screw have the screwdriver seat broken.
This carb is installed in a reconditioned unit, but work 4 year without problems.
Many thanks for your time

If they are available, use a regular carburetor cleaner. If you have a Yamaha dealer, their carburetor cleaner is amazing.

1) Look on the carb for ID numbers, norlmally on side opposite the adjust needles. Normally, two letters and 2 or 3 digits (sometimes followed by a letter).
2) You can find schematic of the carb here: http://wem.walbro.com/walbro/family2.asp Also the repair / diaphram kit Number
3) I believe you will need both screws functioning to hold the gasket and diapharm properly. No leakage allowed. Both sides of carb are designed to be removed for service.
