My Tiger quits as soon as the engine gets hot (about 4 miles) and will not restart until it cools down. I thought either a vapor lock or no spark caused the problem. If the accelerator is pushed down gas will squirt in the carburetor and there is a spark at the plugs (or at least one I didn’t try all of them)
Things that I’ve tried:
Things that I’ve tried:
- Put an insulating plate under the carb.
- Replaced the water pump.
- Installed an electric fan.
- Removed the thermostat.
- Rebuilt the carb.
- Installed a new battery.
- Insulated the fuel line and fuel pump with Aluminized Fiberglass Semi-Rigid Split Tubing w/High Temp Adhesive.
- Moved the coil to the fender, off of the engine block.
- Replace the Petronix electronic ignition with a new set of points, rotor, condenser and coil. (I found an article online about an MG that had the same type of problem using Petronix with a ballast resistor, it seems that there was spark but not enough to run the motor. When I stopped driving the car last fall I thought that this had solved the problem but it did not.)
