How does the choke relay work on a 1981 Toyota corona?
the purpose of the choke relay is to supply power to the choke heater ONLY when the engine is running; otherwise if you left the key in the run position but the engine wasn't running the choke would open up even though the engine wasn't warmed up. then when you tried to start it, it wouldn't start because no choke. the control circuit for the relay usually comes off of the back of the alternator triad winding (alternator not turning=engine not running). without looking at a wiring diagram i can't tell you the details of the wiring but that's the idea of it- engine running turns relay on and sends power to choke heater and slowly opens up choke; key on but engine not running means relay is off and no power to choke heater. if the relay is not working, then no power will go to choke heater and the choke will stay on too long (or if ambient temps. are low it may stay on all the time). fast idle will stay on also as it is hooked up to choke linkage.
What is electric choke?
The choke enriches the mixture for start-up and then is heated by a small electrical heating coil so the choke goes off when the engine is at operating temperature.
How does a choke work?
By cutting off part of the supply of air. This will cause the fuel/air mixture to be very rich. A cold engine needs a much richer mix than a warm engine. Once the engine warms up the choke opens up and the fuel/air mixture is restored to the optimum mix.
What do you do when you have spark and your engine will turn over only when in choke but dies as soon as the gas runs through on a Briggs and stratton 20hp lawn motor?
When you say the engine will turn over only when in choke, I assume you mean it runs while chokedand then dies when you let off the choke. Check the fuel filter,the air filter,makecarburetor adjustments if necessary and ultimately, checkthe throttle linkage.
Does the auto choke stay on the whole time the car ison?
No. Most, if not all, auto choke systems work off the temperature of the engine (usually the intake manifold). When the engine is cold, the choke provides a richer fuel mixture to aid starting and help smooth running. As the engine temp increases, the choke should slowly open. If the choke stays 'closed', fuel consumption will increase drastically, the engine's cylinders will become choked, the spark plugs may become coated with soot and fail to spark and the exhaust may emit smoke.
Bike only runs with choke on turn choke off it goes deadwhat should i do?
clean the carb
How do you start a Weed eater Featherlite?
COLD ENGINE STARTING OR STARTING AFTER REFUELING --Set unit on a flat surface. --Slowly press the primer bulb 6 times. --Move choke lever to FULL CHOKE position. --Squeeze the throttle trigger fully and hold through all remaining steps. --Pull starter rope handle sharply 6 times. --Move choke lever to HALF CHOKE position. --Pull starter rope handle no more than 6 pulls, until engine runs. --Allow engine to run 10 seconds, then move choke lever to OFF CHOKE position. RESTARTING A WARM ENGINE --Move choke lever to OFF CHOKE position. --Pull starter rope handle until engine runs. --If engine does not start in 5 pulls, follow instructions in STARTING A COLD ENGINE.
Your Yamaha 440ss only runs with choke on?
Clean your carburetor's main circuit. Your carburetor contains two "circuits." One is the main circuit, and it puts gas into the engine with the "choke" off. The other is the enrichment circuit, which puts more gas into the engine because a cold engine needs a richer fuel/air mixture than a warm one. If your engine only runs with the choke on, that means no gas is coming in via the main circuit, which means it's clogged. Clean that out good and it should fix the problem.
What should be done if one notices that his bike was rode with Choke ON for about 35Kilometers as engine sounded different?
The Choke simple modifies the air/fuel mixture. It shouldn't be a problem, its just harder on the engine. So just listen to see if the sounds continue, and if they do, take it to a mechanic, and learn the lesson to take the choke off next time. If not, learn the lesson to take the choke off anyways
What happen when you run the motorcycle with the choke on?
Nothing realy.. with the choke on the engine receives more fuel making it easier to run with a cold motor. after starting the engine, wait about two minutes before turning it off.
Why would a 2 cycle engine not start?
== == Basically, the problem is often that, the choke being left "on" continually prevents the engine from starting because there is too much gas for the air being provided. (The choke control reduces the air being provided to burn with gas). On warm days, a two-cycle engine does not need to be choked very much. The cooler it is, the longer you need to leave the choke on. You need to prime the engine by pushing in on the plastic dome that you can see gas in. That sends gasoline into the fuel line. Five pumps or so is all you need. Be sure that the cut-off switch is turned to "run". Put the choke lever into "choke on" position. Pull the start cord twice. That normally provides a good gas/air mixture to the cylinder. If the engine starts, put the choke lever back into the "choke off" position after a few seconds, and let the engine warm up. If it starts to sputter, put the choke back on for a few seconds more. If it doesn't start, put the choke lever back in the "choke off" position. (Yes, even if the engine does not start). Continue to pull the starter cord several more times. then put the choke lever back to "choke on" if it still won't start and start the cycle again.
If a motorcycle engine is turned off and the choke is left pulled out for an indiscriminate amount of time unintentionally will this damage or dirty the carbuerator?
No,it may flood the engine.
