CArotor

i just bought an 85 gs and i can get it to run but it wont rev over 3000 rpm

i checked the spark plugs and the leading plug in the first rotor is like new where as the other three are somewhat fouled

it has a spark but seems to not be igniting anything

can annyone help me

Have you replaced the plugs?

CArotor

the guy i bought it from said he had replaced them and it did not help the problem (of course i know that means nothing)

i also failedto mention that the oil had what semmed like a excess amount of gas in it before i changed it

The oil in my 82 always smells pretty gassy compared to other vehicles I have had. I suggest you go with the easy stuff first; change the plugs and wires and go from there. I don't know if all 1st gens use a distributor, but if yours does buy a new cap and rotor as well.

Also check for any vacume leaks.

i have aleady bught a cap rotor and wires i justtook he uys word for it that the plugs were new cnsidering they cost more than your avrege spark plug) i guess ill hve to break out and buy them



also should i try an atf treatment before changing them

CArotor

put new spark plugs and a fule filter on it today and that did not help at all

Is it getting fuel? Double check spark, then fuel.... you may have a carb issue.

ok, lets see. when you rev it, does it reach 3000rpm pretty quick, or does it get there slowly?? when the engine is running, does it shake like a **** and feels like it wants too rip the supports off?? hows the timing??



You might want to do a compression test. Check the FAQ's there should be a how-to there.

and if you dont already have one get a haynes manual.

CArotor

it takes a while to get to 3k, does not shake.

i have already checked the timing and have a haynes, which does not seem to cover this type of problem

also, i think i forgot to mention that blows smoke

(unburned fule) untill it starts to warm up
