How do you check the timing on a mr2 mk2 gt?

To check the timing on a MR2 MK2 GT, you'll need to locate the timing marks on the crankshaft and camshaft pulleys. Use a timing light connected to the number one spark plug wire, and start the engine. Aim the timing light at the timing marks and observe the alignment; it should match the specified timing value in your service manual. If adjustments are necessary, you can loosen the distributor and rotate it until the timing aligns correctly.
