    Could be the fuel pump, could be the carbs need work, could be the fuel filter, or a problem with the pulse line for the pump, or plugging of the in-tank pickup, etc.

    What did they do when they serviced it? Was it running good before?

    Could be many things, and I'm sure other will chime in with more things to check:

    1. Fuel filter, plugged? can you see fuel in it when trying to start?
    2. Fuel tank vent stuck, easy to test, just loosen the fuel cap when it seems to be starving and see if picks up again.
    3. Plugs? Are the wet or dry when you can't get it to start? Flooded or starved for fuel.
    4. Spark? getting any?
    5. Fuel valve plugged.
    6. Lean, its do a light seize when your going WOT
    7. Compression, if #6 is the case, you may be low on compression and hard to start.
    8. Could be the fuel pump, mine the diaphram failed, easy to check, suck on the pulse line fitting and if you don't get a vacuum then it failed.
    9. Stop start switch issues or layard.
    10. Battery, does it crank at normal speed or slow.

    etc!!!
