Seahorse 6hp with a stutter

[MXZ500]

Gi'day eh
I have a 75 6 hp Seahorse I bought. It's starts pretty good,
but it sorta misses off and on when cold. When warm
It seems to run great. Any insights.
I am in the process of getting a manual, ....but until then.....????
Thanks in advance
Cheers

Re: Seahorse 6hp with a stutter

Have you done the basics?
Compression test?
Replaced plugs?
Cleaned Carburetor?
Check/set points?
Inspect coils?
Do you have to leave the choke on very long or switch off as soon as it starts?

If your slow speed needle is set too lean it will cause the motor to sneeze. Many think this is a miss. Try moving your slow speed needle a little richer (in 1/8 turn increments) and see if problem goes away. If it doesn't then I certainly agree with above points. Best of luck. Rick.
