 If the stumble happens immediately upon throttle opening it is not fuel de=

seconds even at full throttle with no fuel delivery at all.
Here is an easy thing to try even if it is off the wall:=C2=A0 Swap out the=
 distributor rotor.=C2=A0=C2=A0 I've heard said that the rotor can fail in =
a manner where it will withstand the voltage required to generate a spark a=

ry for heavier throttle positions.
Happy Drive Your Triumph Day.
