Thank you for the response

Just to follow up . I got my mower back today and it's worse now than it was . When I fired it up it filled my garage with smoke and then I mowed about 3/4 of a acre and it started surging and missing ,with the occasional smell of fuel. The hustler emblem on back they had started to peel it off also. Now it will sputter without the blades engaged at full throttle . It bogs down and looses power real easily now. I have been in touch with hustler and we've decided another shop might be better qualified. Supposedly the dealer checked: coils,plugs ,cleaned carb and readjusted choke linkage . I guess my question now is, what's the odds of a valve sticking ?

When you go to pick up the mower at the new dealer, start it up while at the dealer and let it run with blades engage and full throttle for 5 to 15 minutes to see if it meets your expectations. If not, leave it there and ask for a demo to take home and finish your lawn mowing.

Bring it back if they are the authorized dealer and make them fix it properly ! I would suggest you do exactly what Breezy advised . It may very well be a valve train issue and its their problem not your's !

There is another dealer 30 minutes away . Hustler customer service is going to take it to them . Thanks for the responses everyone.

Let us know the final outcome :) .

We'll do... There's another dealer coming to pick it up in a few minutes

The dealer one county over (Full Mower Service- Livingston,Tennessee ) came and picked my mower up at 930 this morning and when I woke up I had a message saying it was fixed. He replaced both coils on the mower , adjusted the pumps to where it wold track straight ,fixed my decal the previous dealer tore off and sharpen the blades. He told me the mower was in top shape now but wants to run it just to make sure there isn there isn't other issues . Now that's a lawnmower shop

Great to hear Eliot , well at least now you have one Competent Dealer relatively close by !
