Hey guys! I have a weedeater 85T line trimmer that I cannot get to start. I thought I have tried everything. I changed the piston and ring. I cleaned disassembled and blew air through the carb. I adjusted carb. I checked for spark. I assume since I had spark that the kill switch works. I sprayed starter fluid in carb. I took carb off and sprayed gas and fluid (at different times!) directly into cylinder. Nothing! There is a gasket that goes between plastic housing and cylinder that I mistakenly left off but shouldn't it at least fire? Any suggestions? It was not working before I took it apart but it worked at the beginning of last spring just bogged down a bit. Thanks!
