115 Yamaha Saltwater Series Experts (2-Stroke) - Engine Bogs Out Under Load

[115SWS_2STK]

As of right now you don't need a carb. From your post above, there's crap further up past the fuel water separator/fuel tank/BEFORE the separator..

You do need to at least drain the carbs looking for any debris that made it past.


Might want to try a clean, portable fuel tank with known good lines, plumbed into your engine (carbs at east drained) with clean fuel.


* A new carb with crap in it won't run correctly either*..

Just cleaned out the fuel bowls. Saw a little bit of gunk but nothing too massive came out.

Emptied the carb bowls and tried running on portable. Now it won’t start!!! What do you guys think the reason might be? I squeezed the bulb pretty hard.

verify good compression, spark , and timing again
if they are still good then it has to be the fuel to air ratio is not correct
too much (Rich)or not enough(too lean)
