starter fluid didnt work, you said that if it wasnt timed right, it thump and shake. it shakes when I try to start it. it sounds like it wants to start, but it just doesnt.

so far, i have

new plugs, and wires
new battery
gas treatment
starter fluid

the oil still seems good, and I have checked all other fluid. still nothing

i think that timing might be a factor

what are the steps that i need to do to check the timing while the belt is on. is there a simple check or complicated. if you know the steps that i need to do, i would really appreciate it. thanks
