Hey guys,
I bought old 94 400 L for next to nothing and I am having the hardest time getting it to run. The guy I got it from said that it ran last season. But you all know we all say the same stuff. It will turn over and almost kick off but nothing. It starts back firing through the exhaust and start smoking like it really wants to run but nope. I changed the spark plug. I took the carburetor apart and it is clean as a whistle all the jets are clear and the floats float. I took the reed cage out and inspected the reeds and they all opened and reseated fine. I turned over the motor with the carb. off and it shot out a huge fireball so I know it is getting fire. the thing is when I put my hand over the carb to choke off the air it does not pull a vacuum. I checked the boot or the intake and everything is sealed up tight. I am at my whits end everything is saying it should run but nada
