The genral rule of thumb for compression tests is that less than 100 PSI is out of specification. However, they should have checked all the cylinders because a full test checks to see if the highest compression is within 75% of the lowest compression.
Secondly, I am ssuming it is running rough. If you get a used motr, look around the internet and try to find one that has had a compression test, leakdown test and a start up guranantee.
Most reputable slavage yards will do that. They will drop shipp it to your door for around $100 as well. Also, try to get all the accessories, maybe even the tranny, as you never know when one bracket is just different engough to make the whole thing a parts hunt for that one thing.
I hope this helps you out. Be patient and take your time finding a used engine dealer. Don't go loacl because it is easy or EBAY, unless you by-pass stuff and always look on forums olr anywhere their name will come up to check on theior reputation and customer service.
