Good stuff, thank you, that's going into storage for future reference.
Yes, it was pretty hot, and the saw had a workout prior to shutting it down the last time. But I did let it idle for a minute to let it cool a bit before turning it off...
Interesting, I had not even thought of that. Thanks for the tip.
The hose didn't seem too stiff when I replaced the filter, and I didn't notice it being fouled in the wrong position, but it's possible I just didn't notice...
One thing I wondered about is whether the fuel tank could have gotten pressurized and forced too much fuel into the carb. I had that happen with an E-TEC outboard motor where Evinrude made the fuel tank vent so that it would allow air INTO the tank, but wouldn't let pressure OUT of the tank. (One-way duckbill valve.) Stupidest ****** idea I ever heard. You're out in the boat on a sunny day (who ever uses a BOAT when it's HOT and SUNNY???) and the sun heats and pressurizes the tank, and the pressure has nowhere to go except to push a sh!tload of fuel into the fuel-injection system and ... it's flooded and won't start! Had that happen with a brand-new motor...wouldn't start at the ramp and I had to go home. Glad it didn't happen in an inlet or somebody might have got hurt!
Anyway, thanks again, guys. I appreciate all your help.
