QuestionQUESTION: i have a weed eater and i want to replace the spark plug but i cant find it please show me a diagram of where it is thank you oh and by the way i dont know y it wont turn on please respond.
ANSWER: hi vicki
what brand weedeater do you have ?
sthil, weedeater, jonsered, husqvarna ,ryobi etc to name some
the spark plug would be on the cylinder either on the under side of unit or on the top side of unit depending on construction of trimmer
the high tension cable will be thick black lead connecting it to a cap you can pull off to change the plug,
as to it wont turn on - if it has a on / off button or switch try taking one lead off the kill button & check for spark and replace plug, squirt some 2 stroke mix
(20 mils of 2 stroke oil for each 1.0 litre of petrol you mix )
into plug hole and try to start see if runs on that fuel mix- if so assune spark and compression are ok, but check muffler in case its blocked
next squirt fuel mix into carburettor throat and open throttle see if runs again if not
c/case air leak or carburettor supply problem or carb diaphrams may not be working due to age
let me know what you find and exactly what brand and model weedeater you have
cheers paul

QUESTION: its a ryobi weed eater.
Answerplease find website for ryobi type trimmers
http://www.hammerwall.com/Download_Manual/12139/
as explained plug should be either top of trimmer or at the bottom where the unit would normally sitt when placed on ground to start - it will have a plug cap and a fairly heavy ht lead attached , remove this and replace plug , fuel tank and carb will be to the top exhaust will be @ the bottom
stop button or wire could be contacting earth - make wire is not contacting earth
note does this machine drive the head around as you try to start if so , could be a sheard flywheel key
