hows yer battery? Could be a discharging battery.
Mind you mine does have troubel starting on a hot day after a hot run.
I awlays thought the carb bowls were evapping the fule and not filling.

Maybe enrichen the idle screws a bit?

[Imwildcoyote]

battery is good I actually topped it off with acid and recharged while doing carbs ,have no trouble turning engine over

[JEEPRUSTY]

how many turns out are your screws mine are 3 I think.

[Imwildcoyote]

Have you checked the valves? I doubt it's the issue but it could be.

This era of 550s had some issues with bad ignitors as well.

[Imwildcoyote]

No I haven't checked valves yet , was going to be next step

[JEEPRUSTY]

yes by all means check the valves. That should have been done witht he carbs anyway.

I put new float valve in when I had carbs apart , I'm talking about checking engine intake and exhaust valves

To clarify, Jeep and I are just suggesting you check your valve clearances.

Unless you have reason to suspect there is a problem with the valves themselves (e.g. bent, etc) then you shouldn't have to pull them.

Thank you , yes we're on same page , that is also what I was talking about
