What is the correct air fuel ratio for cold start?
60:32
What is the cold start pipe on the 1987 pontiac fiero gt fuel rail?
There is a high pressure fuel line under the throttle body that carries fuel to the cold start injector. There is a black pipe that feeds idle air to the same spot to insure the cold start injector gets a good mixture.
What is the proper fuel oil mixture for a mercury 60hp outboard?
50 : 1 is the correct fuel mixture
Why do old cars have a choke?
Older (pre computer) cars have a mechanical choke to richen the mixture for cold starting. Cold engines need a fuel rich mixture. Later model cars do this by shooting addition fuel into the engine on a cold start. That signal is sent electronically to the injectors by the computer.
Whats the correct fuel mixture for a suzuki rm80?
whats the correct fuil mixture for suzuki rm 80
1998 range rover started not to perform well it start to have- cut- in running looks like a sick old man coughing what could be the proplem the cut in running only last for few minutes when cold?
check the cold start valve is working and not stuck usually take it out and use carb cleaner to clean it of all the carbon that builds up failing that the fuel mixture is incorrect. if its too lean theres not enough fuel to richen the mixture to aid a cold start, if its too rich it "chokes" the engine both these can lead to poor cold start and running but i would start with the cold fuel valve (solenoid)
Why do exhaust headers turn red after engine runs a few minutes why?
Typically this is caused by a lean fuel mixture caused by either the timing or jetting in the carb is too small. Start by checking your initial timing. If it's correct I'd start checking the fuel mixture.
What is the correct fuel mixture ratio for a 2000 KTM 65SX?

Where is the cold start valve how does it work?
millisecondThe cold start valve is sometimes called the fifth injector. It is mounted to the intake air distribution box and is in line with the fuel rail. It has an electrical connection and a fuel inlet line and a fuel outlet line. S The cold start valve is essentially constructed the same as the regular fuel injectors. The main difference is that the cold start valve injection time is measured in seconds rather than in milliseconds like the regular injectors. The cold start valve receives power from the double relay when the key is in the start position but only injects fuel into the intake air distributor when the cold start valve is grounded by the thermo-time switch. The purpose of the cold start valve is to inject fuel into the intake air stream when the engine is cold (and the starter operating) in order to richen the fuel/air mixture for easier starting. It can be tested in the same manner as the other injectors. Leakage is undesirable as it will cause the engine to run rich. sorry no pics millisecondThe cold start valve is sometimes called the fifth injector.
