^Still! A brand new OEM cam is 200 bucks from our vendor. He's BSing you.

 

Low compression could be them trying to read the compression gauge slowly turning the engine over,or while the decompression release is still on...If it doesn't have sufficient compression=it will NOT run...If it runs,it may be low on compression according to specs,but if it'll start,run smoothly,and haul you,and your stuff around,run it...GO get a 2nd opinion,most shops give them for free...

 

buy a compression gauge and check it yourself. that way you also have the tools to second guess the dealership. but as stated earlier, get a 2nd opinion.
