The start primer rubber bulb must be cracked/damaged. Replacement parts are available.
A primer will usually get it out of the case.
A moving object always experiences drag, a unbalanced force slowing it down. Thus it needs a force provided by the engine to counteract this force. The engine doesn't go without petrol (or some other appropriate fuel) so a car needs that as well.
Batteries are basically the same for petrol or deisel engines, but diesel engines require more cranking force and demand a bigger battery. So a battery from a diesel engine is ok for petrol, providing it fits.
Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.
Works due to combustion i.e. it explodes and and the force of the explosion forces the engines piston away from the force of the explosion, which happens in an enclosed area.
I'm guessing that it is a car I'm going to go with petrol
A vehical that runs on petrol and diesel is impossible as they are both ignited in different ways. For exaple petrol is ignited by the spark plugs and a diesel is ignited by the shear force of the compression from the pistons. A petrol engine has a round 9:1 compression ratio and a diesel has about 20:1 but these veary from engine to engine I hope that hasn't lost you
For a rotational output such as a petrol or diesel engine, the force is Torque, which is measured in Foot.pounds or Newton.meters.
At a basic chemical level, methanol is less reactive than petrol due to polarity. Just like water tends to hold together in droplets, methanol, being an alcohol, has polar molecules which hold the substance together. Petrol, on the other hand, is nonpolar, and doesn't have that force holding it together.
Water molecules have polar characteristics. They have strong intermolecular bonds, namely, hydrogen bonds. But the only intermolecular force present between petrol molecules is London forces which is relatively very weak than hydrogen bonding.
Well, you can't live in the United Kingdom, it's the middle of summer here, and we have gale force winds and pouring down with rain, and it's not that warm either.
The Spitfire uses high octane leaded petrol (gasoline). -What the Royal Air Force calls Avgas 100/130.
