Today,I got a phone call. One young man who is my friend want me to check his D5 for him and the engine sent to our factory already. As usual I asked him what's going on?

Young man:[Hi,Dino.Please check my D5.It's hard to adjust....]
Dino:[Well,what's wrong with it?]

Y:[Hum....can't idling and easy to cut out....]
D:[OK,I will check it for you. Any other odd condition? Are you sure your clutch setting is ok?]

Y:[No special condition,just easy to cut off when I close the throttle. The clutch setting is fine.]
D:[Well,maybe your engine is too old so the compression is not enough to keep idling. But I need to check it personally. How many fuel have been through it?]

Y:[Hum....not many....about 20 gallons only......]
D:[Well,It should be the reason. The piston and sleeve were worn out already. Let me check it for you tomorrow ok? And I will call you back. ok?...]

Y:[ok! Waiting for your answer,bro. bye!]
D:[bye!]

In fact,I really want to ooxx him on the phone but I restrained mine mouth. I don't know I should laugh or cry.... Sometimes it's strange,the same engine some one can use 20 gallons,but someone may only 2 liters?

Hay guys,lean you engine after making sure the break-in process passed already.
