[T2] Power loss in 4th

[Erik Burtis]

Any chance the fuel line is too close to a heat source?  Perhaps the fuel
is boiling with the higher temps of driving up hill and slower rpms not
moving new fuel through the line fast enough.  The fuel expansion could
push fuel into the carb after shutting the engine off.  This characteristic
is the only thing that bother me with a line/tank clogging issue.  Your
symptoms remind me of boiling gas in my chainsaw last summer.  Loss of
power at low rpms, noisy carb, etc...
