It doesn't matter what kind of gas or stabilizer you use- IF your unit
sits for weeks at a time, the gas in the carb WILL evaporate and all
gas will leave some gunky residue behind.
I know this is controversial but ME- I start them, then shut off, drain the
tank, then re-start and run until it starts to miss and then put the choke
on and run till it quits. If the carb has a drain in the bowl I'm sure to
open that and get the last drops out. The honda has a carb drain, so does
my Briggs powered 5KW.
Needed my big 5 KW house genny a couple weeks ago. Had not been
started in 2 years. Stored dry. Put in gas, opened the fuel shut off,
choke on, switch on, pulled ONE time and it started.
My honda EU2000 is always harder to start. Normally takes 5 or 6
pulls whether it was started last week or last year. I store it dry too.
Same for my motorcycle. I don't drain the tank but I fill it completely,
use stabil and then run it till it quits with the fuel valve shut off.
This is what works for me. Others will say "seals dry out etc etc."
I say the carb will dry out and leave residue behind. I try to avoid that.
