550XP starting issues

[AllyH]

My 550xp has become a bit of a pain to start. Plenty of fuel, primed, choke on but it struggles to start. Once it's been running for a bit though will start fine again once it's been stopped. Can anyone suggest anything? Cheers

Choke on, prime, decomp in, pull until coughs. Then choke off, don't prime again, do not decomp and pull until it starts. Is this what you're doing?

Never had any starting issues with mine and have never used decomp on either

When was the last time you changed the plug. Had a similar problem, checked the obvious or so I thought. Morning I was due to hand it over to Dinosaw, I changed the plug. No more problems after the plug swap.

It's a relatively new saw. Not really done a heck of a lot of work yet to be fair. Still the standard plug. Although maybe worth changing?

Avoid using the decomp and see if that helps!

They dont like being run dry if thats any help

[AllyH]

Yea I ran it dry once. Could that be why?

Have you cut cookies to tune the saw ? weather is colder now

With the 560 I don't use the primer to start and I've run it dry a couple of times without problems. If you've got another saw it's probably worth swapping the spark plugs to test.
