How to troubleshoot a 2 stroke engine with no fuel?
2 Stroke Engine Troubleshooting – Spark But No Fuel. As you read above this is assuming you have checked the basics, you know, gas is on, gas in the tank, choke is on. One quick check you can do is to pull the fuel line off your carburetor, turn the gas on for a second and see if fuel is flowing out the fuel line.
What to do if you don’t get a spark in your engine?
If you don’t get spark, try a new spark plug before you do anything else, even if the plug looks “good” try a new one. If you have spark and the plug was dry, move on to “Fuel” If you have spark and the plug was wet, replace the spark plug and try starting the engine again with the choke off.
Why does my Car Crank but won’t fire up?
Worn spark plugs can cause a “cranks but won’t fire up condition.” Worn spark plugs produce a weak spark that’s not hot enough to ignite cold fuel. If you haven’t changed your spark plugs according to the car makers recommendations, they can leave you with a car won’t start when cold or worm condition.
What to do if your engine is not getting fuel?
If the plug is dry and we have spark, we are not getting fuel. So to check the spark we need to pull the rubber cap off the spark plug and remove the plug from the engine. I am not going to get into plug reading as that will be a seperate article in itself.
What should I do if my engine won’t fire?
Check your CAS, i would say you have it one backwards if its been off, take it off spin the key 180* and bolt it back on to test that theory, sounds like its firing when the valves are open. Click to expand… Thanks for the ideas. Well, I will check that, but the CAS has not been off this car EVER.

When does a car engine start and backfire?
Sometimes the backfire is a couple seconds after the engine quits turning. The engine was dead cold (never got it started) & it was like 35 degrees out. I will try & confirm tomorrow if I am getting spark while the starter is cranking.

Why does my scooter not start when I put gas in it?
If you are getting a spark and you are getting gas to the carburetor and the engine is turning over on the starter OK, it’s possible that the electrically operated automatic choke has failed. It’s supposed to operate when the engine is cold, but if it’s stuck or burned out, the mixture will be weak and the scooter probably won’t start.
Why is my 50cc 2 stroke not getting gas?
Well you are still not getting gas. When you took the carb off did you take out the Air/Fuel mixture to clean that out as well? If you did you may have screwed it back in and screwed it in to much and now it is to LEAN and or RICH.
