Try cleaning the MAF (Mass Air Flow) sensor. Use MAF sensor cleaner only and follow directions on the can.
There are "steps" on the choke cam that pull the gas pedal up to a high speed idle when the choke is on. If you don't step on the gas pedal once before starting, the carburator/choke assembly cannot function properly.
The break pedal will be hard to push are when you push the brake pedal all the way down the engine will start running rough are you may even here air sucking / Vaccum leak.
replace the fuel filter and the accelerator cable to the throtle body
I think it is located on or behind the break pedal, I'm not sure how it is attached but it can't be that hard once you find it.
Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
Sometimes a piece of carbon will get caught in the EGR Valve. If is is hard starting, idles rough, and the brakes are hard, check the EGR Valve, it probably has a piece of carbon stuck, keeping it open.
The brake pedal vibrates.
It is very hard.
hard brake pedal is the most obvious sign only way i know to test a booster, is to turn engine off. use brakes several times till pedal is hard. then with brake applied,start engine. the brake pedal should then soften.if the pedal stays hard the booster is bad
Any time the brake pedal is hard to press then you need to check and see if the brake booster is functioning properly.
no if it is hard to step on, the cable might be wore.
has it been running before you try to start. it is overheating or you have a bad starter.
