I have a 1979 Merc 20 thunderbolt and I think that I am having a sync issue. I pulled the carb on Friday because it would not run. Gave it a good cleaning and it started right up and idled perfectly. Great, problem solved? not so fast. Launched it Saturday morning-started right up, idled smothly. Put it in gear at idle-no problem. Went to accelerate and it died. Tried this over and over and it kept cutting out. It would idle in gear but that's it. On a hunch I jiggled the ignition advance lever arm and she took off like Secretariat. Upon restart, some of the time I had to repeat this procedure, while other times it worked like it is supposed to. Is there any adjustment that I can make here? Do I need to replace the linkage?
I read the link and sync in the FAQ section but this motor is rope start.

Thanks,

WM

You are on the right path investigate further. check linkage.
Does not matter if it is rope start.
The motor does not care if it is rope start.
