....starts fine but when it revs down it dies...starts again with one pull w/choke on then one pull w/choke off then when rev it down again it dies...air filter was on but pinched the choke boot and there was a little gap...I guess dirt got in...my question is will a carburetor cleaning take care of it and is it easy to take the carb off and put back on...searched on you tube and didn't really get a good video about it.....checked the fuel filter and looks fine...adjusted idle screw and doesn't make a difference....
