Engine hours and yet another vro question

[fitzms]

Is there an average time in hours you shoud get out of a motor(johno 225 1989)befor things really start to wear out,eg start to lose compression and secondly I understand that the vro changes its pulse rate at differnt rpm but is there a rule of thumb or average rate per minute for say if the engine is at idle?

Re: Engine hours and yet another vro question

Most wear & tear comes from lack of use & poor manintenance/set-up and not hours. You will see an occasional post here with claims of 1-2,000 hours & runnin strong.

The "pulse rates" for a VRO pump varies with the year of manufacture. Read the ENGINE FAQ section, part F. for more info on the VRO and how it works.<br /><br />At idle, most pumps will "pulse" or click about every 3-6 seconds. At full speed they are close to one a second. IF you hear a steady click, click, click sound, one after the other, then you have an internal problem or air in the fuel system. Usually you will also see a lot of blue smoke.
