[QUOTE=butre;48075170]It's a negative pressure situation either way, the difference is whether positive pressure from the piston moving down closes the reeds or the piston skirt physically blocks the intake port (and positive pressure sends excess fuel/air out the intake backwards or into the boost bottle if it's present)
I'm a reed valve guy myself but most utility engines don't have them since it's just another part that could break[/QUOTE]
That as much I knew and I'm with you on the reed valve, I prefer little to no blow back through the carb if at all possible.
It's an efficiency thing, also allows lower idle speeds do to not blowing any/minimal fuel out on upwards piston travel.
yeah reed valves only add a couple ounces but greatly improve the volumetric efficiency of a 2 stroke. The only thing about them is you need more crankcase compression to take advantage on account of the lower intake velocity. unless you're using an absolutely enormous carb you can't make the transfer ports very big either, or else it'll be an absolute dog until you're nearly at max rpm. I'm already using a 20mm carb on my 70cc bike and it's barely enough with the size of my transfers, typically a carb that big goes on 125 cc engines
if you're like me and tend to park indoors then a reed valve is a must, leaking gasoline and oil all over the house is just downright not smart
I need new plug wires for my Chrysler any suggestions #7 plugwire is currently grounding out on the exhaust because chucklefuck thought the lead holders were just for show.
I wanna build a potato gun-type cannon that has the compressey bits out of a refridgetator hooked up to a weed wacker 2 smoke. it could recharge itself.
This you're going to have to explain, i can't fathom it.

Just with a ball valve as a trigger?

I believe he intends to use the weed wacker motor to drive a compressor and fire potatoes via compressed air.

you don't need the chamber if you're going to be using an external tank to hold the air. that space is just there to hold fuel, it'll just mean you need more volume of air if you're not explosively propelling it
dont make it out of pvc unless you want to lose fingers
alignments dont take an excessive amount of time to complete right? Looking at going to get one done tomorrow, but if its going to take 4 hours then fuck that
Should be an hour tops

It should only take 4 hours if they're doing the alignment with rulers and string. They just drive the car onto a machine and push a couple buttons usually.
Well I mean, there is an extreme shortage of mechanics where I am. So who knows.

I do them myself in about an hour using a tape measure, string, and a bubble level

I have zero interest in fucking around with this type stuff. The alignment needs to be done right as my poor unevenly worn front passenger tire is making me mad
Why did I think, I should try buffing my car myself. This is literally the stupidest idea I've ever had, I'm so fucking upset.

Just curb your other tire and make them both evenly unaligned!
No, that's horrid advice, don't do that. Do the alignment instead.
[QUOTE=CoilingTesla;48076606]It should only take 4 hours if they're doing the alignment with rulers and string. They just drive the car onto a machine and push a couple buttons usually.[/QUOTE]
Kinda this and kinda not, I do alignments at the shop I work at and it's a little more involved.
This is for a front only alignment.
Drive car on 4 post lift with 2 rail jacks.
Block rear wheels.
Lift front.
Place slide mats/pads under front wheels.
Attach IR sensors to rear rims. (They look like lazor cannons that mount to the wheel :v: )
Attach reflective IR counterpart to front rims. (these tell the system at what angle the wheel is on a pitch, roll, yaw basis (caster, camber, toe))
Calibrate front wheels to get the angles by rolling front left wheel forward then backward then level according to computer, same on FR wheel.
Place steering in level position and install wheel lock, just a bar basically that hold it in place while adjusting stuff.
Lower car onto pads.
Bounce car to set suspension to a natural stance/level/position.
Adjust tierods/caster/camber to proper angles according to computers database, it's graphical so you know when it's at the right spot. (depends how new or updated the system is.
Undo everything and your done.
It [i]really[/i] only takes 15 to 20 mins depending on how fast and/or dangerously your moving, or if you forget a step like I do. But over all it doesn't really take that long so long as its a simple alignment,if things are really off then you HAVE to dick with camber and castor, but normally with non modified suspensions you don't.
It's really the very best thing to get any worn bushings or other parts, including bad shocks/struts replaced before getting an alignment as it's only becomes a bandaid for another problem, which can cost a ton more in the long run.
I went to an autocross today and drove my friend's miata. Was pretty fun and was pretty different from when I last took my E30 out. Ended up missing 2 runs due to the car overheating though

I'm gonna take a wild guess and say you melted through your paint
The new takeyari pipes are already being awesome!
Got pulled over for them because you're not allowed to have exhaust extending past your bumper.
Lucky for me they're NOT exhaust! They're not actually hooked up to the exhaust system, just some pretty pipes bolted onto the frame. :v:
He gave me my license back and said 'be safe'.
I was feeling pretty smug.

Bigblocks are so fucking dreamy. So soothing and relaxing.

why aren't they exhaust what kind of lame shit is that
The timing belt was finally changed in the Supra. But we realized that the big bolt for the crank pulley wheel is missing, so I still can't start it up :tinfoil: I also ordered a new clutch, which I hope will be arriving this week.

Probably because its illegal to have your exhaust extend past your bumper, just like the friendly cop told him.
so, my car failed inspection like a month ago on some different things, one of them being an airbag warning lights... and obviously my airbag is blown. so does anyone know of a way it'll turn on as if it's testing the airbags, and then turn off to say they're ok?
I don't feel like replacing an airbag on a car that isn't worth anything.
You can solder the leds out in the clock
no, it failed because it wasn't lighting up. the inspection guy barely noticed it aswell, he actually gave me a paper without it on, and then he came back and was like "wait a sec, give me that back" and came back with one with it on there.
I tried taking a couple of wires from another lamp that did similar as what an airbag light is supposed to do, but I just ended up destroying the lights I was trying to take power from, somehow.
I know repainting is something you think about when your car is actually done but I was wondering what paint scheme you guys suggest for a E12. I was thinking about matte black, I know its not really original but it seemed nice. But I don't think it will fit a nearly 40 year old car
Also, why did the American E12 have big ass ugly bumper
