Starting 52cc brush cutter

[Denise0121]

I have nightmare trying to start said machine consistently. This time started and used fine. After refuelling I accidentally knocked choke on and engine now flooded. Tried and tried to start but couldn’t so gave up. My question is what starting procedure is required for it now? Still prime? Choke or no choke? I’ve learnt that 52cc prefer throttle open when starting so I’ve been doing that. Which did seem to be successful. Until this particular nightmare. It’s a forest master 5 in 1 which is great… when I can start it! I’m only slight and have nerve damage in my hand so after 20 pulls I’m about done in! Any help would be very much appreciated!!

If you flood it - open throttle wide, choke off and crank it over a few times. Idea is to blow the surplus fuel out of the cylinder, because it is far to rich and probably shorting the spark plug. If that doesn't work, remove the spark plug and repeat, plus cleaning and drying plug before refitting. Then try a normal start.

Before you take the plug out and spin the engine over check that the ignition system is not electronic! Does the brush cutter have an On/Off switch or it tied into the throttle?

If you do take the spark plug out make sure the metal part of the plug body is held firmly against a metal part of the cylinder before spinning it over. If you don't you could easily damage the ignition system.

So many small machines have unprotected (from 'Back' EMF) electronic ignition systems - used to be my Saturday morning pocket money job changing the electronic ignition on small machines.
