How do you set timing on Isuzu kb250?

To set the timing on an Isuzu KB250, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, align the timing marks on the crankshaft and the camshaft as specified in the service manual. Adjust the distributor position to align with the specified timing mark, usually found on the front of the engine or on the timing cover. Finally, secure the distributor and check the timing with a timing light, making any necessary adjustments.
