It could be many things i would start out with a tune up if you haven't had one in a while it could not hurt anyway. If that don't solve the problem you will need to put the vehicle on a diagnostic computer.

Hi

the battery is weak although it may have power to turn the engine over it is not enough to make it start, it will need changing. the other fault is common with loosing revs while turning full lock. this is often a loose power steering belt or power steering rack or pump starting to fail. to be honest though they seem to last forever like this and there are a number of wheel related faults such as bottom suspension arms, ball joints and bushes that can also make the car do this as the steering is extended beyond where it's maximum capacity is.

Hope this helps

Needle fallen into the needle jet? Blocked exhaust?
Please get back to me if you require further asssistance.

sounds like your carb could be blocked with dirt if it wont start unless you put juice down plug i would take the carb off and give it a good clean and also make sure the jets ok just clean them with carb cleaner and a paper clip

sounds like mixtue screw ,ave a fiddle its the screw wiv the spring on it ok , or take off air filter and try

check the timing and the catalytic converter,,,if the converter is clogged it wont run
