comp. = 115#  should be enough to fire or at least fart, imo.

ignition maybe questionable

old fuel was poured out and replaced with fresh mix?

spark plug wire ok?

as others have mentioned.... spark plug known to be good? or flooded with fuel mix?
---------------------------------------------------------------------------------------------


if it were me....

remove and dry the spark plug, with a propane torch. burn off wetness or water/excess oil/carbon.

you squirted fuel in the carb, but not the cylinder as 'man of stihl' first suggested.

good advice.  this should always be done first, imo.

if it farts or fires, the comp. and ignition/spark plug are much less likely suspects.

let us know what happens.


.......if it does not fire or fart, the comp or ignition or both are at fault.
 



only after it fires or farts after the first test.......


now, perform second test by squirting fuel mix into the carb.

if it did fire after this test you would know the problem lies in the carb or possibly air leaks.



its difficult (without guessing) to determine exactly what the problem is, or even eliminate
possibilities unless the first test, is performed first.


hope it helps.
