Brought two refugees home from the dump, Echo straight shaft weedeaters. One had the throttle and interlock handles broke off. Put some gas in the other and it would start on choke but would die when the throttle was opened just a crack. Took carb apart and it looked clean, pump diaphragm looked good. Soaked carb body in acetone for a 1/2 hr, reassembled and still no joy. Swapped carb off the other and she runs like new!!
I plan to try the lemon juice soak on the bad carb and see what that does for it. How hot does the juice need to be and how long do I cook it? Any suggestions??
I disassembled the throttle assembly and removed the interlock. There's still enough of the throttle handle to run it. If I get it running I'll buy a new throttle handle or just keep this one for spare parts.
