Not getting gas?? runs with a shot of starting fluid for about 7 seconds

I think you mean it wont run after running out of gas. You may have to remove the spark plug and shoot a small shot of starting fluid in the hole and replace the plug. Cranking means turning the engine with the starter motor.

i run my macs at 30.1 gas to oil and standard bar oil should be adequate, good luck finding a manual...

Is it getting fuel? Have you tested the fuel pressure? You may have a faulty fuel pump or fuel pump relay. Can you hear your fuel pump buzzing. Remove your gas cap and have someone turn the key to the run position while you have your ear near the open gas tank. You should hear the pump making a buzz. If you don't hear anything you have a bad fuel pump or problem in the electrical circuit to the pump. If you do hear it running you still need to check the pressure. If the pump is buzzing it still may not be working correctly. You could try giving it a shot of starting fluid and if it runs on the starting fluid you know you have a fuel related problem. Be careful with the starting fluid because it is very flamable.

Try a small shot (about a 2 second spray) of starting fluid in the air intake then cranking....
WARNING- DO NOT TRY AND KEEP IT RUNNING BY USING THE STARTING FLUID! It can damage your engine.

If your bike fires and runs for a bit, the most likely problem is your gas has gone "sour". You need to drain all the old gas out and properly dispose of it.

Over time, gas will cause a varnish buildup in your carb if it sits too long. You can try adding some carb cleaner to fresh gas, but the results will not be immediate. You may have to have the carb rebuilt.

When you store anything gas powered, there is an additive called Sta-bil that will act as a gasoline preservative for about a year.

Try using non-ethanol gas. It's death on small engines. Starter fluid gives it a boost if higher octane. Have a reputable repair place clean out the gunk, then use good gas. Best of luck finding non-ethanol. Boating marinas carry it.

Listen for the fuel pump prime cycle.
Have someone listen back by the gas tank....turn the key after it has been off for at least 10 seconds to run position....you should hear a WHIRRRR for about a second or 2.
If it is silent....you may need a fuel pump.
Next give it a shot of starter fluid...if it starts on that...you indeed have a fuel problem.No start....no spark.
If no start and you did hear a pump cycle....then it's most likely a no spark problem.......a common cause is the crank sensor and/or ignition module.

have you checked the fuel filter for any dirt in it ??

Hi There,
Try this: You will need 2 people - Have someone Spray Starting Fluid in the throttle then start the car and have someone spray the fluid continuously into the throttle. If the car continues to run you have a fuel problem, but if it stalls out, replace the coil pak. Hope this helps and thank you for using FixYa!
