oh the glory of the82-83 civic wagons. hold on to this gym because they are slowly dieing out (i have killed about 3) and they are hard to find. i swaped a h22 into mine, one of my three and i couldnt keep it still always wanted to smoke tires (made me proud by the way) but i put in a slip diff and that saulved that issue till a drunk driver nailed it two weeks ago so if u wanna sell this old girl let me know.

thanks for the info ...very much appreciated...i will try what you explained about the water into the carb through the hose...also where is the idle speed adjustment screw located?? couldn't find mine..thanks once again...

[cvcc_wagon]

is it a Cali. car? the idle adjustment is on the back of the carb on the passenger side, if it is a Cali. car you will have to undo the two bolts that hold those hoses to the bottom of the air cleaner set-up to reach it.

[83Civic]

i am not sure if its from cali, is there a someone that i can tell if its from cali?? i live in Oregon and thats where i bought it from.....

[cvcc_wagon]

if the engine looks like this with the two black boxes that have all the vacceume hoses it's a cali. car

[83Civic]

hey just took a look at my engine........same exact..

[Condor]

If you are close you can take the air filter out. Mine's in a box they should not notice. I'm not close, though, but the car is 100% tuned up and running well.
Person on another site said he ran his car almost to the E and put in a gallon of methanol.
I'm skeptial this is bad for my engine.
I posted that, but no reply yet. If I don't hear from anybody, next week I plan to take the filter out, and put in a gallon of methanol assuming I can find it.

[cvcc_wagon]

not methanol, methyl hydrate. 2 very different things. my experience with methyl hydrate have been mixed, it does help to raise the octane a point or two but nothing more than that. the stuff burns cooler than gas so it's not good to run with that for very long. a gallon is quite a bit i think, it comes in 1L bottles by me and thats all i would want to put in at once i think, just run your tank pretty empty when you add it.

Dude at work told me methyl hydrate is methanol. i'd rather run ethanol but only way to get it is at the ABC store lol. i've got to get my HC down some bottom line for 15 mins or i've gotta get a new cat i think and i'm freakin broke right now.

[cvcc_wagon]

it's not, alcohol is an entirely different story. lots of gas companies add 10% ethanol to boost octane cheaply.
ethanol can be hard to get without some concentration of water, the highest you can get is 95% pure, anything more is near impossible to make but most places don't like to sell that because of liability, 190 proof will get you f*** up real quick. you typical drug store methanol will have quite a bit of water in it so you will have to find a supplier that has pure stuff. methyl hydrate is relatively safe and can be found at most gas stations. it will not make all your problems go away, all it does is raise your octane.
