Johnson 20 hp 1967. Need help!

[Dawson130]

have a Johnson all new ignition system but is very hard to start. The cam follower is not riding on the guide under the flywheel so the butterfly in the carb won’t open. I’m assuming the hard to start problem is because of a fuel issue. It will try to start but only runs for a couple seconds then shuts off. Any help is appreciated! Thanks in advance!

Get that cam follower to operate the carb properly.

Is that linked to the starting issue?

The cam follower must just start to open the butterfly in the back of the carb when it hits the mark on the cam. Loosen the bolts on the cam and adjust the cam to make it so. When you have the choke on, the cam follower may not touch the cam, so adjust with the choke off.
