So after the tohatsu mc 40 crapped itself finally found a replacement powerhead had it sent from cairns to sydney it was only one to be had mechanic looked at it wasn’t too confident as you could see light corrosion in crankcase and told me to send it back.so wrecker said you can send back but cant replace it as there are bugger all around tell mechanic to pull it down first and see if its ok . Mechanic does and says it should actually be ok and strips and cleans it all good so today we fit it using all the old carb electrics flywheel etc on starting only running 1 cyl compression test all ok so pull off fuel pump diaphram buggered pull pump off 2nd motor (twin setup) still runs rough ok must be crap in carb mechanic tells me to do it as I’ve done a few times pull apart and crap everywhere i have spare parts galote so deap with another carb all good now just have to buy a new fuel pump and hopefully all good those 2 stroke motors are bloody strong
