This question is in the catagory for computers. You will have a better chance for an answer in another category.

The running on choke is caused by a fuel restriction. Check the fuel flow from the tank to the carburetor.Change the fuel filter if it has one. If its good, then the restriction is in the carburetor. The generator is shutting down due to the low rpm coming from the engine. A carburetor rebuild may need to be done.

Check for floating debris in fuel tank possibly restricting fuel flow thru screen on bottom of fuel pickup;

Good test. Do not keep doing that.
Make a new and accurate gas/oil mixture. Empty and refill. Secure cap. Be sure to flood system during start attempt. Can you smell gas? Oops, too much, better wait 30 seconds for full evaporation.
Two little screws near carb. Both are actually needles and probably have a visible spring which keeps them from vibrating to a new position while in use. One fuel/air mixture at low idle (start). One fuel/air mixture at high RPM.
Try 1 1/2 full turns open from fully closed. Once to get it to idle roughly, adjust to a smooth idle. Do the same at full throttle. You will notice that the more you shut the full throttle down, the higher the RPM will go (assuming that it is near correct). Do not run it to lean. The mechanics of the motor needs the oil from the gas.
Smile always.

Follow the Accumulator (round silver cylinder) low pressure hose to the fire wall. You will find the low pressure service port valve just before the fire wall.

Make sure you don't over charge the system, add small amount at a time and check the temperature every 3 min to 5 min by placing the A/C on max with the engine at 2000 RPM.

Once the temperature coming out of the vents are cold as ice with the engine at 2000 RPM. stop charging. So turn the recharge valve on for 20 seconds and then off then rev the engine to 2000 RPM for 3 min and check the temperature at the vent.

Once the temperature is ice cold, stop and don't over charge the system. Over charging the system will cause the A/C compressor to shut down and at worst break, causing a $500.00 repair cost.

Good luck and thank you for using fixya.

Low on R134a, you need to have the system recharged. Try to stay away from the do it your self kit that most Auto Parts store carry.
Below are normal car AC pressure readings with 134A

Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Thank you for using fixya and good luck.

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

Most Likely Low on Freon. Low Pressure switch shuts That Compressor Off.

hi,i asume that ur laptop runs for sometime in the fresh start, then it shuts down....check for the CPU temprature, the fan RPM must be low , not sufficient to cool down the CPU, give it a try,, secondly even the RAM can cause this problem,, go step by step to eliminate the culprit.. let me know
