I did not get the engine from Bob just the replacement parts,
One would think that all DL engines are built the same no matter who you buy it from, DL need's to get there quality control to a better level and consistency like most other contrys do,
I have a DA as well and you cant compare the two, they are different engines and price as well, My DL runs strong and reliable but I do not think it will last as long as my DA,
