rough running command 13

[southam]

Runs rough and seems to be possibly not firing every time...wondering if something gotloose or broke , My guys ued it after three mount bolts fell out and the motor almost fell out , it was shaking violently..Also just discovered that the idle mixture screw does nothing , runs the same all the way in and 5 turns out ..

The carb needs cleaning.
If you can turn an idle MIXTURE screw more than 1/4 turn in either direction without drastic engine changes then the idle circuit is blocked.

Check all the carb controls for bending.

Check the coil cut out wire for chaffing and grounding out.

Thanks BERT.........Carb was cleaned and ports are clear...Cleaned flywheel and coil and set armature space with an index card..Going to try to run it in the dark maybe see some electrical jumps.. I'm a Jack of all trades , or what you pros call a "parts replacer "but learn something new every day . Thanks for your time
