My MS260 has been getting extremely flooded at start up and is impossible to start using all the tricks I've learned. There's fuel mix coming out of everything; muffler, decomp, and carb. Spraying(!) out after only one pull. One day I got her running on the first pull and she ran like nothing was wrong, though I did notice the L was too rich as she'd bog if layed on her side. Tuned her and ran her for a few hours limbing a few oaks. Thought my troubles were over. That night, I couldn't get it started... Flooded like crazy and I never even engaged the choke at all. I ended up turning the L all the way in. Seated. Closed. Still flooding badly with fuel pouring out of the muffler and carb. Today, I pulled the carb and decided to try and clear out the bottom end, so I removed the plug and pulled her over a few times. Gas spraying out of the impulse line. Lots of it with each pull. I thought the impulse was for pressure/vacuum to manipulate the carb's diaphragm and act as a pump... Is fuel supposed to be coming out of the impulse? I've pulled it about 60 times with no carb, and still fuel continues to come out of the impulse. Huh?!?! So confused as to how the gas is getting there. Never replaced, removed or messed with either line.
