i just bought it the other day and it has sat in storage for the last two years i cleaned out the gas tank and filled it with fresh gas after changeing the oil. It will only run if the choke is on and it wont go above idle of it will die and it will die if you turn the choke off.
Thanks For the help

GUNK

The gunk you had in your gas tank is exactly what you have in your carb bowls. If you can pull the drain plugs and drain the stuff out that would be a great start. PERHAPS without removing them you might get out on the road and crank the throttle enough times to actually get the gunk through the carbs and get the needle valves and floats freed up enough to work properly...start it up and use the choke to keep it going, only enough choke to do so though and as it gets more time on it then keep moving the choke till it is completely off...as soon as you can...and just keep changing positions of the throttle and working it...IF it just won't work you'll have to pull the carbs and rebuild them, andthat is not fun, but it won't kill you eithter...bottom line is you will know for sertain tha tyou are getting the job done right when you get into it. If you are going to an aftermarket muffler and pipes you should rejet and that would solve the rejetting right there. Freakinout has a link or atachment for the carbs that he has posted...good luck on freeing them up...don't forget to clean and reoil your airfilter...

Tear em down and clean them carbs.....

Although the short cut is to hit the rear of the carb with some cleaner while running. There is the main throat of the carb and usually 1 or 2 small openings ( depending on the carb ) in the main throat. Spray the smaller hole or holes with some cleaner while running and with choke off. Yeah, you will need a hand working the throttle to nurse it like this. Don't stick ANYTHING in this to try an open it up.

Tearing them down to soak them in a can of carb and parts cleaner would be best though.
