How do you Push Start your car??

Team,
I am very sorry for this stuiped question but i have never push started a car, well i did with my RX7 but it didnt work. I'm afraid i didnt push start it correctly. Basically all i did hooked up a chain to my car and to my friends truck and he was pulling my car at about 15 miles an hour. As the car was rolling basically alli did was have myh clutch down and turn the key.
I've heard of poping the clutch but please tell what method worked the best for you guys. Im pretty sure my engine is flooded, but i want to see if i can atleast have it up and running by push starting it.

Nathan

take your plugs out and crank it to blow all the fuel out. hold the gas pedal to the floor while doing it. take a lighter to the plugs and let the fuel burn off. this will ubflood your motor.

Yeah, what he said to unflood it. To push start it, you should have the key to where it is when the engine is normally running. Once the car is moving, put it in second, and let your foot off the clutch. The spinning wheels will be spinning the tranny, and when you release the clutch, the tranny will spin the engine. Usually you do this if the battery is dead, or you got a bad starter.

driving around with the clutch on the floor an't gona anthing but waste your time LOL... the engine isn't even turning. once moving. you gota put it in gear and drop the clutch. this will start to spin the motor (like the starter would but harder) if the key is turned to "on" the car should start running. you can also do it by just rolling the car.

Yeah, the reverse gears teeth are not at an angle (helical gears) to the face of the gear, they are straight (spur gears). That is why reverse makes that noise when you back up. The teeth clack together. The forward gears have helical teeth, or teeth at an angle. The teeth don't suddenly joint together, they ease together and engage for a longer period, and the contact is spread out across the face of the teeth. Click on the link to see what I mean.

like they said, 2nd gear, ignition in the run position, get up to speed, then let the clutch out, and tow it along until it starts

my first car with a very dodgy conversion took maybe 1/4 mile at around 25 MPH before it started running by itself.

Interesting... Tho that doesn't jive with my understanding of why race boxes(and a lot of porsches) use straight cut gears. I always though straight cut were stronger. After reading the how stuff works, I have a feeling that the transmission loss would be decreased with the straight cuts as well, since you have less sliding friction contact areas between the teeth.

straight cut are stronger due to the direction of the force on the gear. helical cut gears have the main just of force acting at an angle to the gear's face. straight cut have the force acting more perpendicularto the face. also all straight cut gears that i have heard about use dog engagement which i believe takes up less room then a standard synchronizer engagement. this allows for a wider gear of course. i don't believe that reverse gear use any synchronization however. thus why most manual cars make a clunking engagement sound when engaging that gear.
