Re: Outboard cleaner?
Get a standard pin and poke it through a piece of paper. The hole is way bigger than the hole in the nozzle in a lot of small engine carbies. Restrict such a tiny hole a bit, which takes almost nothing, and it's delivering less fuel than is required to mix with the air coming through the carb to give the proper air-fuel ratio for combustion and if it's reduced enough then nothing happens when you open the throttle.<br /> <br />Most likely it's a blocked or restricted high speed system in the carb. Doesn't have to get dirt in it. Fuel leaves residues in the carb, especially if it's been sitting for a while, that will easily restrict or block it. <br /><br />If the nozzle is at the bottom of the system then that's where the dirt and gum and gunge will most likely be.<br /><br />There also has to be an inlet for the fuel from the float bowl to the nozzle, which is going to be somewhere between the cap and the nozzle. If you were too generous with the sealant, you might have blocked that passage off entirely. Assuming the sealant hasn't been dissolved by fuel and carried further into the system to block the nozzle. Either way the result is no high speed system; it runs only on idle; and when the idle system shuts down on opening the throttle (which takes only a slight movement of the butterfly) it dies. <br /><br />Get the right seal for the cap or make one from oil jointing paper or gasket material, which any auto parts shop should have, and let us know if it solves the problem.
