I find a cast number on the engine block RH under exhaust

Customer Question

I find a cast number on the engine block RH under exhaust manyfold. It is a G7S4FR7. What engine is this and what NGK spark plug does it take?
JA: How many miles are on the car? How has your mileage been lately?
Customer: This is a custom made farm vehicle. It looks very old, at least model 2000. I find the motor missing frequently and want to replace the plugs.
JA: What is the model of your '00 Mitsubishi?
Customer: It was a COLT double cab. But apparently the diesel engine got replaced with this petrol engine.
JA: Are you fixing your Colt yourself? What have you tried so far?
Customer: I am fixing myself since the vehicle is not registered. So far I have turned the fuel adjustment screw on the inlet right to the L lean position.
JA: Anything else you want the mechanic to know before I connect you?
Customer: More problems will surface in future. But up till now this is my biggest problem.
