2 cycle gas weed eater repair advice needed
i have a troy built tb35ec trimmer that doesnt want to start.
i replaced the carb since it sat up for a while and put in a new spark plug because old plug had a weak spark. it didnt want to start or even try to start.
thinking the cylinders were dry from sitting up for a while i added a few squirts of oil through spark plug hole and it felt like it had a bit more compression to it and then she actually fired up and ran for a minute but died right away and refused to start up again.
after letting it sit for an hour, i tried again and it started and ran for about 2 minutes filling the garage with smoke before it lost power and died.
it never would start again after that. i tried another new carburetor i had on hand (they sent me two by mistake) just in case but it made no difference.
it wont even spit or try to start with starter fluid so im thinking that eliminates a fuel problem and i have lots of spark. i put new plug and triple checked it many times to be sure its clean and sparking good throughout all this BS.
i tried two different brand new carburetors so that should eliminate any carb related issues. when i tried to repeat what i did the first time, adding a bit of oil directly to cylinder to increase compression, it didnt even spit or try to start at all. im thinking this has to be something simple.
i am in this until the end with this thing and refuse to be defeated but i dont know what to test next. i usually fix these things for other people, but this one isnt a simple carburetor or fuel filter issue. it has spark and its getting gas, and it has "some" compression albeit hard to tell how much.
dont all 2 cycle engines have reed valves on them? where is the reed valve? im thinking that would be the next logical thing to check but i dont see it shown on any parts list diagram.
You can only learn if you ask the question, so there are no dumb questions.
