I'm helping a buddy with his 50's era 10hp that won't start.
He bought it from a guy who had it running a couple years ago.
So at this point, the engine won't run and my gut tells me something in the carb is the culprit.
Is there a circuit that we should be looking at?
Can we remove the reeds and attempt to start?
What do the reeds actually do?
I'm assuming the high speed circuit (needle that threads into the float bowl) wouldn't be affected on initial startup
It's a sweet motor so doing my best to help him out. His 10 year old son is anxiously waiting to go out and do some fishing...
I'm familiar with this era of motors, having owned a 1960 5 1/2 and currently a 1967 3hp folding motor.
Thanks so much,

- Motor spins and appears to have good compression. (Thumb Test)
- Spark plugs fire with healthy blue spark. Installed new plugs
- Carburetor looks very clean and fills with fuel, float working as fuel flow stops as float rises
- He sprayed a small amount of fuel into each cylinder and the motor fired and sounded healthy for a few seconds
- I had him check the reed valves for sticking and he says they're clean and functioning
