Pawo and others, this is the power i need, whats the safest way to adjust the alda and and how would i be able to clean the switch over valve for the banjo line, just wd 40?? i know it still works cause it clicks when i put my air pump to it and see if it still worked.

for the past decades ive owned the car i used to use a good bit of kerosene in it and diesel mixed. could this have affected something in my motor? but i havent use kerosene in the car for about 8 years.

my plan is to do a diesel purge with this stuff called diesel kleen, replace the fuel filters again, new injectors, new glow plugs, aftermarket air intake and ill leave the valve adjustments for last if i dont get any more power.

but no one has answered my exhaust question, the black smoke when i punch it, and if i need my exhaust replaced cause its restricting power.
