Not running it on petrol often enough will cause the injectors to gum
up, using a full tank of petrol may clean it out.
If it doesn't the injectors may need to be removed and cleaned.
I suggest switching to petrol just before you finish with it for the
day, start it on petrol then switch to gas when it warms up, this should
keep the injectors clean.
