50cc 2 Stroke Tuning? Answered

I have an old moped that I got for cheap and I am trying to fix it up. I replaced the carburetor and the new one is a little bigger even though it is off of another 50cc. It insisted on running extremely lean, but I was able to get the fuel/air mix balanced by putting some foil tape over part of the intake to get more vacuum behind it. It will only run right if the exhaust is on so that it is not lined up perfectly with the exhaust port on the cylinder. If the exhaust is taken off it will start first kick, but if it is lined up the way it should be it will not start. I took it off today and when I put it back on as close to the way it was before it would start but is now running very lean, beyond what I can tune out with the carburetor. If I give it full throttle it bogs and has no power, but it has fair power at 1/3 to 1/2 throttle. It also is getting really hot and has absolutely no power once it gets very hot. Yesterday I hat it all just right and it ran with none of these problems except that full throttle was still not where it got full power. Does any one have any ideas about what I have to do to make it run right? Maybe there is no option but careful misalignment of the muffler? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It turns out that the problems were that the muffler was clogged, and that it was running too lean at first, but too rich once it warmed up. Thank you for you suggestions.

Updated Revolver

Updated pictures. I tried an 8 turret afterwards and it was too heavy and big, so I stuck with a 4 turret, which keeps it light. My picture quality is crap, I hope to get my hands on a camera that actually works soon, but here it is. 1. A picture of the whole thing. Things that have changed: - 4 Turret has been added. - Iron sights have been added. - Charging handle has been added. - Handle has been improved. - Fore-handle has been replaced with a grip. 2. A picture without the stock. 3. Looking down my original (and very effective) sights. 4. The gun at an angle. Notice the charging handle sticking out and the size of the grip. 5. FPS shot. Not much to say here. This is ighly improved, I hope to be able to make detachable clips soon.

Help with 7 color LED and Arduino requested.

I want to power a 7 color blinking LED from RadioShack (http://www.radioshack.com/product/index.jsp?productId=3060680) I want the power to the LED to be constant so it stays on. I will have the ground pin connected to ground. I want the switch pin to be hooked up to a pin that I can have it go LOW or have it go to ground, and then have it delay I guess, and then have it go to LOW again so it changes colour. Please help me out. I am very new at C programming and I haven't found anything on Google. More info on LED: http://www.seanliming.com/Docs/Articles/MSGBB557TA_7_Color_LED.pdf I want the Arduino to automatically change the color's of a 7 color LED. The LED is connected to power with the anode, and ground with the cathode. There is a third pin that if momentarily connected to ground it will change the color of the LED. Code similar to this but having pin 11 change from LOW or ground to OFF if possible. I need constant power to the middle pin, constant ground to the pin on the far right, and momentary ground with delay to the pin on the far left. I am getting an Arduino Duemilanove in about 2 days, and I want to write some code for it so I don't have to wait to do anything. I already wrote a rather long police light sketch that has different light patterns using just the LED's and the "delay", "HIGH" and "LOW" commands. I just need to know how to set pin 13 or whatever pin as HIGH without it interfering with the code at all because it will mess up my whole sketch. Code: void setup() { pinMode(13, OUTPUT); //Constant Vcc+ pinMode(12, OUTPUT); //Constant ground pinMode(11, OUTPUT); } void loop() { digitalWrite(13, HIGH); digitalWrite(12, LOW); digitalWrite(11, LOW); //I need this pin to be able to change state with delay without interfering with the other pins. }

How can I make a USB to 56k Modem or Ethernet to 56k/fax Modem?

I'm trying to reconnect my Sega Dreamcast to the internet, the trouble is that it only has a 56k phone-line modem. How can I "slow down" my internet for it, without spending $30 on a store-bought (http://www.usr.com/products/modem/modem-product.asp?sku=USR5637) or editing my computer's registry and using its internal pci modem. (http://dreamcast-talk.com/forum/viewtopic.php?f=3&t=1956).  What would you guys recommend? Thanks in advance. :) Edit: As far as I know, Dreamcast communicates like a PC does on dial up - though sometimes there's not enough voltage through the line. Could a spare dsl modem be reversed, providing a dail tone and 56k? This is a better option for me than all the other methods mentioned because its automated and more like using actual dial-up. (No registry edit, no manual line swap, no voltage line regulator

Help on Simple Flashing LED Circuit

Hello, I was wondering if someone could help me with a (hopefully) simple electronics project. I wanted to recreate the flashing properties of flashing construction signs (see video below) with LEDs. I bought a 555 timer and created a circuit similar to the diagram below. I ran into a few problems though: The period of the LED's on/off cycle was normally 90% on and 10% off. With some tinkering of the resistances I achieved about a 1:1 ratio of on to off but to replicate the traffic signs I would like about 80% off and 20% on or less. This circuit is somewhat bulky to make only 1 LED blink. Ideally, I would like to have 20 or 30 either all running on the same circuit or all self contained (with less complicated circuitry). At this point I almost want to get my hands on an old flashing construction sign if only to copy the circuit but I know of no way to do so legally. If anyone has any knowledge of these lights or suggestions of any sort, I would greatly appreciate it. Thanks, Daniel P.S. I have a very limited knowledge of electronics, so feel free to dumb things down a bit. Flashing Lights from Peter on Vimeo.
