Evinrude 115 stalls when put in gear

[crestlinermusky]

Hey Everyone
I have a 1975 Evinrude 115 that runs great but started to act up this weekend
At home on the muffs the motor starts up and idles perfectly, when I put it in gear, no problem
Now this is where the problem starts,when I put it in the lake. It starts right up, let it warm up and when I put it in gear under a load,
it stalls , it starts right up again and by the second or third time it has stalled and restarted. I am good to go and it will not act up unless I
shut the motor for more than 30 mins.
Do you think this is a throttle cable adjustment or a carburator adjustment or cleaning

What's the RPM at idle in the lake? It may be too low. If your RPM is good I would look into carb adjustment.

Compression and spark test are to be done first, followed by a fuel sample into a clear jar. Post results.
