I picked up a 76 TL and i've done all I know to do to get it to start and it just won't. I cleaned the carb really well, and the jet is definitly clear. It has spark, and i set the timing to .15mm as well as cleaning the points. When I pedal it doesn't turn over, but when I put starting fluid in the air intake it does back fire. Any suggestions would help. I got it from an older guy who never did anything to change it, and the ground wire is intact. Seriously, any ideas are welcome.
