Thread: Choke problem?

if that's an electric primer, no choke butterfly in carb, like mine is then when you push in on the key it gives it a shot og gas to get more you have to push the key in again. I have to hit my key 4 or 5 times to get a good prime once it starts, if it is cold ,I give it a shot when it sounds like it's going to die.

Wannabe, That's what it looks like but I can't find anything on the switch that shows a charge when the key is pushed. I have a momentary switch switch I can hook up. Just gotta run the wire
Thanks

If that is a carburated motor the wire going to the switch should be Yellow/Black

Bill, The wire at the carb is black the other is blue. I just don't think they wired the switch

That is strange. Yellow/black is industry standard and should be in the harness. I've given away most of my manuals so I don't have one specifically for your motor. It would make sense if your motor was EFI as they do not have a choke.

That motor doesn't use the switch for cold start enrichment. In this picture, items 14 to 17 are cold start enrichment. It's done automatically, not by use of the key. My motor had symptoms like yours. I spent quite a bit of time on my carbs getting them set up right. I doubt it's the enrichment devices, more than likely tiny passages blocked. If you want more info, PM me your phone #.

You might also check & make sure your fuel line bulb is pumped up full. My 1999 Merc 90hp 2strk will not start easily, even when choked, if I forget to pump the bulb

And since it's on a pontoon, you have portable gas tanks ... so make sure you have the vent valves open, too.

Pappy, I pump the bulb 1st thing and a couple times while cranking it. My tank is a built in 35 gallon, I'd hate to have to carry that to the pump. :-)
