1979 Johnson 6HP Seahorse saga

[nopocustoms]

I just upgraded my trolling motor to a 1979 Sea Horse 6 HP. 6R79E, it worked great for a few minutes at low speed then died. The ball was soft, after squeezing it fired right up again, I was able to troll by having someone squeeze the ball every 5 minutes...

So I rebuilt the fuel pump, and ran it with the outlet hose unhooked, it squirts fuel - I hooked it back up, same thing - ran great but died.

I now assumed the needle and seat were sticky in the closed position, and the pump just couldn't over power it.

Next I rebuilt the carb, everything seemed hunky dory, now it runs very rough - seems way fat but doesn't die...

I am suspect of the low speed needle adjustment, it was out 3.5 when I took it apart is that too much?

It seems to run fat even at high speeds.... I am about to give up and buy a brande new boat with a 4 stroke honda.......

ok buy boat with 4 stroke honda.... mail 6hp to me
3.5 turns seems like alot to me, suggest you lean low speed adjustment to where it runs best (smoothest) then turn a tad richer.
As far as the "
I now assumed the needle and seat were sticky in the closed position, and the pump just couldn't over power it." I am not buying it, the primer bulb clearly unseated them in order for you to be able to run period... likely not stuck closed. thinking that your low speed is out of adjustment, and thinking that you may have set the float wrong when you rebuilt it. they are very fluid level dependent.

1st i would lean the low speed mix, 2nd check timing to make sure your proper (link and synch) then if those two (free) things don't give you desired results.... look at the float level.
