Hey Step - I’m not an outboard guy, but I do have a lot of stuff with carburetors. To check if that guy’s needle comment MIGHT be correct (could also be a plugged passage or jet in the carb), and you can drop the float bowl, if there’s gas in the bowl, you’re probably getting gas to the carb(s).

That would be after checking the fuel line like Phat said and being sure you’re getting good fuel flow past the filter. For that, I’d test it by pulling the fuel line off the gas tank and motor and putting some air pressure in the tank end to see if the flow is good. Pretty gentle pressure should send a good flow.

My $.02 worth.

The problem with removing the bowl is if I do than to reseat it with the gasket is very hard u less you remove the carbs,and I don’t want to do that. Only last resort. But if I hold 5he bowl in place and back off the screw holding it ,gas should leak out through the screw hole. Right?

yes

I disconnected the fuel line going to the carbs,I blew air through it and the bottom carb blew gas out of it but not the top carb. I did get it started and seems good. I shot carb cleaner through the carbs while running. And she ran for a l9ng time till I shut it. Now ,will she start tomorrow? I will let you know. If she starts then I think she is good. I***8217;m hoping it will be good
Scook I did what you said with the air. So far so good.***55357;***56842;

I’m going to start it today and keeping my fingers crossed. She starts. I will post it here how it went.

No good. It started on the first try Great, then it stalled out and didn’t start again. But I noticed that the primer bulb is rock hard ,so there is no gas flowing to the carbs, is 5here @nything that I can do without removing the carbs? What to look for.
