Recommended Posts

we have a stihl br 350 blower at work that would not start, i had a look at it the spark looked faint and when i looked under the casing a stone had got jammed in between the ignition module and the flywheel, its scored the flywheel a bit. could the fly wheel have rotated on the shaft knocking the timing out??

i want to try and check/test components before buying replacments as some of these parts arnt so cheap.

thanks carl

Pop the flywheel of and look at the key, if it is gone and is moulded in to the flywheel, you have a challenge to guess its position and lock it in place. It can be done but is in no way easy.

A weak spark wont be caused by a damaged keyway so it may be fine. If you bend the end of the plug away from the central electrode, you may be surprised as to how strong it actually is.

Check the key and go from there, it may just be a carb issue or seized piston.
