My V20 is always playing up if not in constant use. Try full choke using pre-set trigger on handle (pump the primer 2-3 times. After half-dozen pulls try easing the choke down slightly & prime fuel again. If its not responding with any sign of life, use choke off and prime 2-3 times with full trigger pressure on handle. If you get sounds of life try feathering the trigger (accelerator) with patience mine eventually comes good but requires light feathering until it eventually catches full spark or clears fuel?.
Like Mike I might have to replace it (now running on repaired fuel tank) but is this not the BEST little machine on the market?? (I believe it runs a Mitsubishi crank) - a quality item that has endured over time.
