Engine starts and runs for a very short time 2-3 seconds as if it runs out of gas...fuel bowl full and have taken carb apart and blew out the needle valve jet, but no difference in running...I did check the gas cap and it is o.k. also checked fuel flow and it is o.k. I had a cdi problem before and solved that, but now I have this problem? help!

did you adjust your idle a little higher,turn the screw clockwise 1 or 2 times.
is your gas petcock in the on posistion. is your gas cap venting right.
did you put your choke down after its running.
 
I agree, check that fuel is flowing from the tank by pulling the line and draining it into a container. It should trickle out, but not "pee" out if you get my drift........

Check to make sure that head nuts are tightened, and that the intake gasket and carb to intake tube are sealed tightly.
 
did all that and still nothing....


Solved ......Muffler was clogged ! how do you clean it out? This is the black one with the catalitic unit....?

take muffler off,spray carb cleaner down threw top part of muffler,and im not sure if you have to flush out with water after,and hang up somewhere to drain out,when dry put back on.

its best to do this outside.
 
not many cleanned

A clogged muffler? Wow, how much running time do you have!

not many cleaned here either ----- in a whole lot of years
it is a THING to do talked about around here on site
so a while back I cleanned my first MB muffler
shot some WD-40 in there
held my bike to the side and drained it out

would I do it again ?? yes I guess -- when -- in a few years maybe
why ?????????????? that's a good question

Same thing happened to me the first time I rode it to work. Got ready to leave, had a couple of people in the parking lot watching. Pedal, start, die. Pedal, start, die. I was running out of energy and self-esteem. I hopped off the bike to examine a little closer and found that one of my wires leading to the magneto had come loose. Plugged them back together, started right up and drove home. Felt like an idiot!!!
