Clutch isn't adjustable on it... you have 2 possible issues. Either like Al says it's overcharged, or you have a common issue with backyard / novice R134a conversions...
If the system was not COMPLETELY flushed of R12 and oil and even a small amount of oil was left, AND if the system was not vacuumed VERY low prior to filling, the R12 oil & R134a oil and/or R134a oil and moisture in air mixed, producing an acid that eats through the compressor's mechanicals and can cause it to seize. When I did my Jeep's R12 > R134a conversion I replaced everything but the evaporator (didn't want to take apart the dash to do it). I flushed it fully.
