It all depends on the CHT. If it’s more than 70-100 °C you easily incurr in a vapor lock. That’s how the TSIO-520 behaves.
Just run the fuel pump for at least 30 seconds. This will recirculate the fuel in the fuel lines with two effects:
- Convert fuel vapors into actual liquid fuel
- Cool down the fuel lines for a while
