intermittent power loss evinrude

hi, i have a 30hp evinrude 2 stroke. when i apply throttle i get intermittent misses in power. the more throttle i put on the less time between misses. it seems like starvation of fuel. could this be a problem with the carb?

 

Try a pair of new plugs in it.

If it was fuel starvation how could it keep recovering. Try pumping the bulb as it does it????

 

I would run it for a little, sometimes it fixes itself. Sometimes it gets clugged up. Change your spark plugs and with high octane gas run full throttle. See what happens.

 

While you change the plugs, check for insulation cracks in the wires, coil/magneto, all ignition parts. Could be deposits in the carb if it's been sitting a while.

Here are some more things to check:

after changing the plugs
check the sync of the linkage take a good look at pick-up timing and the throttle cam roller
