@SER_GTR i replaced clutch and pressure plates on a GA15DE, it also needed distributor seal from where it was leaking oil, i replaced it and i marked the position of timing at distributor so that when i install it, it can go easily. When i started car it started easily but when i drove to check the clutch, clutch and gearshift were perfectly normal but engine was sounding bit heavy and wasn't revving like it used to do before? acceleration is bit sluggish, did i retard the timing more? how to adjust timing correctly on GA15DE
