Its to the point I have to take my Stihl with me also so I. On normal cold startup with a 2-stroke dont expect it to run with the choke on.
Remove the cover Remove the cover on your tool we used a Husqvarna chainsaw to gain access to the ignition system.
2 stroke engine not starting. Most petrol hand tools will be powered by a 2-stroke engine and while they are in some ways easier to use and lighter than a 4-stroke engine they can still give the keen gardener a bit of trouble. One of the most common problems is an engine that wont start. Here are some basic things to check if you are having trouble.
When your engine turns over but wont start it means the engine is having a hard time creating a spark producing compression or receiving fuel. If you hear the engine turning over the problem has to do with the starting motor system not the engine itself. When 2 stroke engine troubleshooting and the engine is flooded you want to spin the engine over fast with the throttle wide open several times.
You should start to hear it pop just keep pulling or kicking and holding it wide open until it starts then rev the engine a bit to. Remove fuel line on carburetor and check for fuel flow. Clean filter on tank valve.
Make sure gas is not over rich with too much 2 cycle oil. Please check your user manual for proper oilfuel ratio. If engine still does not start proceed to step 8.
Two-stroke engines are easy to start so if yours does not spark or start when you kick or pull it a few times it means that something isnt right. Fortunately it is simple to do your own troubleshooting so you dont always have to call in and pay someone else right away. As a result rather then start it kicks back on the starter.
Being a 50cc engine it should have only 1 piston. If it is a 2 stroke it will fire every time the piston comes to tdc. If it is a 4 stroke it has to have a timing point that excites the ignition system for every 4th stroke tdc.
For a no start 2 stroke engine with your described condition a possibility to consider is too much unburned 2T oil in the lower combustion chamber. Then turn off the choke and allow the engine to continue running. If the engine wont start repeat the process from the start by turning the choke back on priming the engine and pull-starting.
If after several attempts at starting nothing happens the engine may have flooded. Post by Pony66 onSep 11 2011 at 1239pm. Sep 11 2011 at 1038am inthebox069 said.
I have a 2003 yamaha vino 50 cc it gets spark and if i shoot starting fluid in it it still wont start. So anyone know what might be going on with it any help would be great. Joined Apr 12 2011.
3 Aug 8 2012. This probably wont help but I know that mine needs the ignition on before it will start. With the electrical problem you had I would check out the ignition circuitry.
I have a 49cc 2cycle engine that I replaced the carb on. It has fresh gas and appears to have a spark. I cant get it to fire even if I put some starter fluid in the air intake.
It seems to have compression. The motor has sat for a few years in a garage it did have old gas that I clean out of the tank. Mark is here to walk you through the steps needed when diagnosing your two-cycle engine issues.
These steps will be the same for all the two-cycle tools in y. Fuel level too high. Float valve worn or stuck open.
Starting technique incorrect when flooded kick with the throttle wide open to allow. More air to reach the engine No spark. Spark plug fouled broken or misgapped.
Spark plug cap or high tension wiring faulty. Spark plug cap not in good contact with spark plug. Many 2-cycle engines have problems and are sent to the junk yard before their time.
Typical problems include hard starting rough running a need to adjust the carburetor during use to keep the engine from stalling a need to rev the engine to keep it from dying and not starting at all. I will assume the user knows to replace the spark plug. Just curious what some of the problems are that cause a 2 stroke to not start after it has been run and then shut off.
I bought a Hitachi leaf blower last fall and I love it except for trying to start it hot. Its to the point I have to take my Stihl with me also so I. If you performed the fuel test and your tool did not start at all you will need to troubleshoot the ignition system next.
The ignition system includes the spark plug spark plug wire and the ignition coil. Remove the cover Remove the cover on your tool we used a Husqvarna chainsaw to gain access to the ignition system. Replace the spark plug.
Simplistically there are three things your engine needs before it will start. Fuel compression and spark. You need to ensure it has all three.
You could start by removing the spark plug grounding its body with the plug lead connected to it set the controls in the starting position and pull the starter cord while watching the spark plug gap. How to start a two-stroke engine. Straight from the horses mouth one of MowDirects experienced engineers shares his secret starting tip for two-stroke engines that are proving difficult.
He has used a chainsaw engine as an example but the basic technique should be interchangeable. Put your Chainsaw on to choke. It doesnt make sense that heat is a factor cause its already hot when the engine was running youd think as soon as it does get hot the device would stop working and the engine would stall.
Gonna borrow an impact gun and see if that works if not Ill have to take the right hand cover of and hold the primary gear bolt. Flywheel keyway isnt sheared I dont think because the flywheel spins with the motor and wont slip when I hold it and push on the kick starter but who knows until I get the damn flywheel off. With pratice you will learn to tell the difference between an engine dying due to not enough choke when cold or one which is choking itself on too rich a mixture choke on for too long.
On normal cold startup with a 2-stroke dont expect it to run with the choke on.
