Husqvarna 128r Brushcutter (Easy Flip!) 

I learnt the hard way when refurbishing a husky 128 that cheap sparkplug are crap and make the engine run really badly. After struggling to tune the carb and a lot of high speed missing, I swapped the plug for a proper champion one specifically for this engine and it started and ran sweet as a nut..!

nice job, i just bought the same model for 25 euros to flip (non runner). fitting new plug, fuel lines, filter and recoil mechanism.
