It is a 98 kx60 it is really hard to start and it dosent seem to have any power up high or down low.is this because it needs a new top end?

This could be many things, but start with the simple ones. Test ignition module as they have two sections, one for low rpms and one for high. Check for restricted exhaust, clogged cat converter or muffler. Check for correct fuel pressure AND delivery.

Maybe a missing part?

There are only two problems with electrical circuits. Too much amperage or too little amperage.We have to determine what you have.
An excellent test is to put your test meter red lead on the positive battery post and the black lead on the negative battery post. Crank the engine and record the voltage. Then place the red meter lead on the starter's battery terminal and the black lead on the negative battery post. Again crank the engine and record the voltage. The two voltages should be with in one half volt of each other. If the voltage difference is greater that one half volt, there is a resistance in the circuit, somewhere. I would expect the voltage to drop a volt or two, max
If the voltage dosent drop, there is high resistance resulting in low amperage. If the voltage drops too low then there is low resistance resulting in high amperage.
High resistance=dirty terminals
Low resistance = shorted wire, slow turning cranking motor maybe caused by bad starter, bad battery or hard to turn engine. ( engine bad, alternator or power steering pump bad, a/c pump bad, etc)
Can use head light for test. Turn on lights and note the brightness. Crank engine. If while cranking, the lights stay bright= high resistance.
If lights go dim = low resistance.

98 caviler high beam left side dosent work canged bulb checked fuse and all good

the cc on these are low, its a low power saw

need to replace dryer and the orifce tube vachum down and recharge, you have contamination in your system.

Sounds as if converter on exhaust is getting plugged up. have it checked and replaced. That will force exhaust out ahead of it where ordinarily it would flow with less pressure. Oil leak is a separate item.

check power steering fluid if real real low you have a leak at hoses or pump seals.if all is good check for low tires and lack of lubrication to at ball joints and tie rod ends. if all is good you have power steering pump failure.

Easiest way would be to go back to where you bought it and make sure the bulb is installed that you bought....and show them. Ask if you can get a new bulb and change it in front of him. Call the dealership and talk to parts, ask if, indeed the hi and lo are interchangeable.

Need to resit the timing.advance it.
