Making an MGB GT Run Right Again | Timing, Valves & Carb Tuning

Getting a classic engine to run properly is all about the details. In this video, I set the valve clearances, track down timing issues, dial in the ignition using a timing light and custom markers, and then baseline and fine-tune the SU HIF4 carburetors on my MGB GT. Once the car’s running right, we end the day the proper South African way — with a braai. If you’re into classic car restoration, engine tuning, or SU carb setups, this episode covers a lot in one go. 🚗 Car: MGB GT 🔧 Work: valve clearance, ignition timing, SU HIF4 carb tuning 📍 Goal: smooth running engine Chapters: 00:00 - Intro 02:19 - Valve Clearance Instructions 04:47 - Valve Clearance Adjustment 09:26 - Timing Light 11:22 - Adjusting The Timing 13:09 - Troubleshooting 16:16 - Custom Timing Markers 19:26 - Carb Tuning Instructions 20:59 - Baseline The Throttle Plates 23:21 - Fast Idle/Choke Adjustment 24:08 - Baseline The Fuel Jet 26:23 - Carb Fine Tuning Instructions 28:53 - Carb Fine Tuning 31:11 - Braai Time!
