Yeah this is the reason why I am worried about this job and also worried about losing the current performance/setting of the engine by intrusion of somebody who is not known with all the factors involved. Another thing is, no mechanic here is aware by the fact that it uses a dial gauge to adjust the pump, the one whom I told that it uses dial gauge to adjust the pump, he said to me " nai nai bao g, o pump la key tey labatri pejna penda aye "
