How to do you set timing on 86 Isuzu pup 2.3?

To set the timing on an 86 Isuzu Pup with a 2.3 engine, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Next, locate the timing mark on the crankshaft pulley and align it with the timing pointer on the engine block. Adjust the distributor by loosening its hold-down bolt and turning it until the timing mark aligns with the specified timing degree, usually around 8-10 degrees BTDC. Finally, tighten the distributor bolt and recheck the timing to ensure it remains in alignment.
