Makerbot Replicator 2 cant print for some odd reason

[Feliks87]

I'm pretty sure my right head nozzle is clogged
the filament string that came out of the nozzle first (now nothing comes out anymore) is way thinner than the string that comes out of my left head nozzle


as for the filament hitting the nut... I tried feeding the hot end by hand without the motor assembly and couldn't get filament through the nozzle easy enough... needed a lot of pushing just to get this thin string out of it
I just ordered some spare nozzles to see if that helps when I swap the right one with a new one
