Hi, I just recently rebuilt the 3 carbs and put new plugs in my 1999
Johnson 60horse on my 17' Montauk.
I can get the throttle about 3/4 the way forward and then in
just bogs down. What I just notice today though, is that I can push
the throttle all the way up and then, intermitently push the choke and
get full speed and smooth running out of it!
I'm thinking that the throttle is giving more air than gas and that
might explain why the additional choking helps? I'm no mechanic, so I
may be way off, could it be the other way around? Once I know whether
it needs more air, or more gas, how would I adjust this? Is it the 2
cables coming into the motor that go to the plates? 1 must be air,
another gas....
Any help is greatly appreciated! It seems like the engine is only a
small adjustment away from being great and I just bought the boat, so
I'm looking foward to having it running well soon!
