It's a gasoline car.
Someone told me that you can use a little bit of diesel and let it in through the air intake of the carb and it will clean the engine quite well?
I don't exactly know what measurements all of you have, because I'm from Spain.
But to me normal tires usually are 13 inch, 14 inch and 15 inch rim and 65 to 75 mm of rubber from rim to ground.
And what I mean with sharp objects is places like these...
