Satsuma Engine knocks and feels underpowered

[SomeDoodOnThe N E T]

So i started a new Save, built my Satsuma, and the Engine Knocks and feels underpowered. Why is that and how can i fix it? I have looked through my Save File if any Engine Parts are damaged but no, they are not. The Carburetor and Valves are tuned Correctly, i checked. Please, i need help

UPDATE: I got it fixed. I sent it to Fleetari and that son of a bitch finally fixed it.

if it happens again just adjust your timing and distributor... I didn't have a knock but I left my distributor loose after tuning on the go and after a short period it got very sluggish and lost all power. in fact I though my parking brake had glitched out and got stuck on but it was the timing being off
