Honestly, need some more info from the OP. Is it just hot starts that are causing the problem, or cold starts too? What choke starting procedures are you using?
Me THINKS yer dealer was blowin' Hot air up yer BLOOMERS. You should have SMACKED THE SCHeeT out of him and asked for a refund. My DAD had a new McCullough like that and couldn't give it away..I bought a 3 cu in Jonsered in 1982,, that saw was perfect in winter.
BUT, if you ran it in the summer,, shut it off,, sometimes it would boil the fuel tank EMPTY!!
Part of that fuel just dumped, but, it seemed that some of that heated fuel flooded the engine.
Forget starting that saw for 2 hours.
The guy that sold it to me told me I had to idle the saw for a lot longer than you would imagine to cool the saw before shutdown.
THAT fixed the heated fuel problem.
The dealers story was that the saw was designed to run in a colder climate than Virginia,, hence, the saw heated itself,, on purpose!!
Maybe the Husky is designed for colder operation?
Could it be like the Stihl, and have a "Winter Air Diverter" that is installed in the wrong direction??
Possibly, and probably,, but, it was a WAY superior answer compared to a shrug of the shoulders.Me THINKS yer dealer was blowin' Hot air up yer BLOOMERS. You should have SMACKED THE SCHeeT out of him and asked for a refund. My DAD had a new McCullough like that and couldn't give it away..
Lou Haverkamp (the Gambes store dealer/owner) never made it right.
Sadly all saws even of the same model are not the same, you get ones thatI have had my mkII 550xp few weeks about . Cold I prime it 4 or 5 times, takes 4 or 5 pulls usually to get a pop and pretty near 5 pulls after to get it to stay running. The part throttle position works like it almost doesn't have one. If it worked like most normal saws i think it would start much better. Was expecting it to start very well when i saw it had a primer bulb. Thankfully it isn't extremely rough or hard pull to turn over the engine .
Warm starts on this saw haven't impressed me yet either. Hopefully it will get better as I get to know the saw or make some easy adjustments. Letting it idle 5 minutes before shutting it off every time is out of the question. I think if i can adjust part throttle up it would start better. Min
BUSHWACKER< you do not mention PROCEDURE, so let me outline and you respond? (Mine a 570xp, works well, consistently). 1) COLD you pull choke OUT, crank 2-3 (OR until pop), push choke back in and it starts next pull. 2) HOT= Pull choke out, then push BACK IN (to cock the FAST Idle), then pull and it starts. If your FAST idle= too slow, then turn screw in 1/2-turn and try, if not enough, add another 1/2-turn?I have had my mkII 550xp few weeks about .

It would be helpful to know more about your specific operating circumstances such as altitude, air temp, etc. I have owned owned two new 550Xp Mk2s and there are a couple of things I experienced. Trying to start “by the book” wouldn’t always work, but once you learned the necessary technique you could start them easily and consistently.550xp mk2 purchased mid 2020.TS
The main concern is that we have 6 of them, all 6 behave the same, & at the same time we use stihl 400c & 500i purchased in October 2020.
They are used side by side in every class, but we end up giving up on thr 550's
I thought starting like that was frowned upon except for top handle saws, or a climber in a tree.Is it just the students who have problems with it?
also, I wouldn’t even waste my time teaching ground starts. Teach them how to start a saw like a man, hanging onto the throttle with one hand holding it wide open, while shoving the saw away from you and yanking the cord with the other hand.

I guess I'm not in the super pro class of loggers yet.Only by insurance companies and lawyers...
You have to know the rules to break the rules, and understand when breaking one is actually safer, to be sure. I guess once you get used to drop starting in the tree, it becomes second nature to do it on the ground, too. I definitely agree a ground start, especially for novices is much safer.I guess I'm not in the super pro class of loggers yet.

Of course I choke it until i get a pop which is usually 4 or 5 pulls, then I push the switch lever down where I assume is fast idle and it's usually 4 or 5 more pulls to get it to hit and stay running. When it starts fast idle doesn't feel much different then idle. Don't recall messing with fast idles much in the past, but i need to adjust this 1 I believe.BUSHWACKER< you do not mention PROCEDURE, so let me outline and you respond?

Should have the chain brake on when starting a saw in all positions i believe .I start my 40cc saw like that but anything bigger I do the ground technique, my cs-400 almost starts just by touching the recoil. I'm only 5'4 so the drop technique is alil risky on bigger saws especially this one. If you can drop start this your a bad@ss for sure. Do you have the chain brake on when drop starting?View attachment 966190
