I would tear it down & see what condition it,s in. Sometimes you can do a simple ring-valve job & freshen it up. If it needs more than that check with Jaspers like 51GM. say,s. Theres is a complete reman. If you are in a large city they will pick it up & deliver it. Or you might arange a drop off point. Great product & good warranty & service. I,m thinking it,s quite a bit more than $1000.
