    yes still new but i was inform  by a honda service  shop that honda does not  cover anything under  warranty for  carb, and that if i bought it in to his  shop i would have to pay to look at it and  fix it
     
    so must  for Honda suppose to be a good engine  co

    I would of thought it would be covered under the emissions control warranty(mandated by EPA) which does cover carb. I guess they would try to blame you for it.

    Does it run okay once warmed up?

    that  what i was told  by service  tech-- he has a hard time get honda to approve any  warranty  have to show show something was  wrong-- that the  trouble with warranty-- really not  worth the paper it printed on- just  ask all the people  with  car  trying to get the  motor  co to fix  it
     
    ok  back to  engine  , yes  after a 3 to4  try at  starting it  does  run,, hot seem to start good,  but  cold that a  differnt  story, get it  started it run then die--

    Sounds like an auto insurance company I am dealing with right now.

    Does the choke appear to be properly working? When it does warm up does it run with no problems?

    choke appear to work as it  start but when i move choke, when i got it  started- it run for a while then die
     
    warm up might be my  problem as i move the  choke when i start it- maybe if i leave choke on for a while  ?????????
     
    when  warm yes it run with no problem so  far
    the book does not  say by i wonder if a  person  should left  choke for a while when it runing  cold then slow move it open
    as i way i was do it when started, move choke to full open and it  die soon after

    You shouldn't have to leave choke on long, engine should warm up fast.
    Do you have any adjustments on the carb?
    Have you had this problem since you bought it?

    one problem I never had a HONDA  before


    tried  started this morning, got  started and pull choke off- well it die after a min

    tries  started and full  choke it started and run poor  but keep runing. slow I move choke   mid  open it keep  running and a bit  faster after a while full open, it  run


    try a  few time after it cool   off, had to use choke  again



    there is one  adjustment on  carb for idle speed

    and yes I had the problem since I bought  it, but then  never left choke on for  warm up either  all was turn  it off when it  started, never got to warm up, im beginning to think,  i have to leave choke on for a while

    Might take some getting use to.
    Might try bumping idle speed up a tiny bit, this may help keep it from dying.
    Problem is nowadays to keep the emissions down they are leaning them out.
    Bought a stihl chainsaw a few months ago, started right up and idle perfect at dealer. I get it home started it up cut a small tree and set it down. It cut off started it back up cut off about a minute later. Only one adjustment idle speed, bumped idle up and works great now.
