yea Aaron told him with measurements he could tell him or get him close. Its just very strange?
the only thing i see making sense is what you said carey, maybe even your sugestion Cali!! haha
But i think in my mind the only thing that makes sense is that he has some super old and or rigged/neglected possibly home made something...ditchpump maybe that he found on a farm or bought at auction or CL and he knows its a yanmar engine but its connected to something like the pump and there is no way in his mind to identify the motor from the application cause he does not know the rest of the contraptions maker, its homemade from many parts, all the paint or id tags are gone??? But it still would take a concious effort to remove the id tag off a yanmar. And i still dont see how youcan miss an intact id tag. UNLESS it was leaking oil and slobberring fuel so bad that dirt is just caked all in the oil mess and it has 1/4" of grime on it and he just hasent wiped it clean?
