The D handle sounds perfect. I hope they are good size as my hands are bigger than most, definitely worth a try. Thanks
thinThanks for the feedback. Answers :
1) Best I can tell - woodruff key, slot in crankshaft and flywheel appear perfect. Flywheel only has one slot.
2) Coil Bosch - 2 204 222 114 - I worked with local Stihl dealer in 2011, when I selected and installed these parts. I understood this coil to be same as 1124 400 1305.
3) No hydraulic lock or flooding.
Additional info - no kick back until maybe a year ago. Began very rare - now it's almost every pull. Can't express how violent kick back is. I use heavy leather gloves when attempting to cranking it. I have enough hand grip that the Stihl rope grip / handle folded as rope pulled it between fingers.
Rope is about 40" long. If I pull rope slowly to full length, kick back only occurs first time piston goes thru tdc.
Could a bad coil or trigger be the cause ?
Thanks. I'll start search for a coil, and check for carbon. I think a person would have to experience the kick back to believe the magnitude.
No, the spring felt good. I adjusted the lever slightly, set it perfectly level.
Saw had shown very minor symptoms of this issue for several months, just worsened suddenly, to point it's not usable. Interesting, up until now, it would idle for minutes - running just not stable at partial throttle.
Re trying old coil - I think I'll pass - I'm probably lucky to still have my arm. I can relate to "Grabbed". One day, determined to crank it, I counted over twenty consecutive kick backs. I have a fairly strong grip, but learned that was not a good idea - one kick back pulled the "T" handle between my middle fingers, folding original handle to "V". Ended day with broken pull cord.
Re valve jet - Stihl tech gave me part number 1124-121-5403 - ordered it today.
I asked tech if there was a way to test a valve - pressure/vacuum test from venturI end. Mine has no restriction either direction .
