Firing order is 153624. Therefore watch the valves opening and closing. Adjust rocker gap when valve is closed. Distributors wear over time. Play in the shaft will adversely affect timing. Best to buy a new one . Easy swap.
starting to work on restoring a very similar mk3, i dont have a spark so im thinking theres an issue with the distributor. Any advice on ways to start diagnosing the issue? I am very inexperienced in mechanics lol.
