I had the same problem 3 years old, maybe used 10 times - removed the air filter and the washer started fine. The air filter looked fine - I have not tried to replace it or figure out the root cause. I was just happy to get it running again :)

SNOW GIANT WONT START please help me turn it on

An engine needs compression, timing, an adequate spark and the right amount of fuel in order to start and run.

When attempting to diagnose trouble each one of those requirements must be checked in a fairly logical sequence and when all are present the engine will start. If the engine doesn't start and run then one or more of those requirements is absent.

A new spark plug correctly gapped wouldn't do any harm at all but as it fires using an ether spray it would indicate a lack of fuel is the problem.
The correct operation of the choke if it is a strangler type should be observable by looking down the carburettor bore.

I have a 2007 rx 350,it is a petrol engine. It cranks over as normal, but wont start.the battery is brand new. It has a full tank of petrol,the engine oil level is good,the trasmission oil is good.

Nick, I would start with the easiest things first and do a simple elimination until you figure out exactly why it won't start. #1 Spark plugs. #2 Spark plug wires. #3 ignition coils.#4 air/fuel filter. #5 Fuel injectors. #6 Fuel pump. #7 Electronic control module(ECM)/computer. If these things I have stated are replaced with new, then there is no reason it shouldn't start. I gave you this list as easiest to hardest to replace. You may find that the problem is only with the spark plugs, then obviously you have detected the issue and do not need to continue replacing components. I hope this helps, and good luck. ^^

3650 generator won't start!!

I assume that the spark plug are good and the gas line is clear. Try to adjust the gas line supply and default engine startup revolution settings try it full half and minimum back and forth it works. Other gen sets requires a mix of oil with its gas, please do it when it is required with exact proportion. Hope this helps. Goodluck.

Start with fresh gas and a new spark plug.

Then follow theses steps.
1 Turn ignition on
2 If equiped with a primer, prime it a couple of times
3 Turn to full choke
4 Set the throttle lock to full throttle
5 With short quick pulls try to start
6 when you hear the engine fire shut the choke off
7 A couple of more pulls it should fire
8 If it stalls start over from step 3

Good Luck

Brand new Honda Generator 2000i will not start. uhhg

Hi and welcome to FixYa I am Kelly.

Things that must be verified.

1. Fuel selector: ON
2. Start run sw: ON
3. Oil Level : Full
4. Choke selector FULL ON for no more than 2 pulls initially The half choke then off
5. Spark at the Spark Plug YES? NO?
a. No spark suspect low oil level sensor is grounding the ignition either due to low oil level or it just is not working properly.

After doing all of the above...

Spark Plug WET or DRY? Dry and still won't start check fuel supply. If you use the choke with the start run switch in the off position the spark plug should get WET. Spark plug does not get wet... with choke on and ignition off. Fuel supply problem.

At this point I suspect either the Oil Level is incorrect or... that the FUEL SELECTOR is OFF.

If you need more help just respond here and we can press on.

Thanks for choosing FixYa

94 intruder 1400 wont start

Ok you have done all that is needed so far but as I understand you are saying that it is trying to turn over? How fast does it turn over? And do you have spark? Test the plugs by pulling one of them out at a time and grounding it to the engine and try turn the engine over a couple secounds while looking at the plugs. You should have a bright blue spark form all plugs. If you are needing any more help let me know.

I can't get it started. It was my Uncle's who

Tips for starting gas powered garden tools.

1.) Drain old gas and replace with new gas.
2.) Make sure oil/gas mix ratio is correct 50 parts gas 1 part oil.
3.) Pull spark plug and replace with a new one or clean the old one.
4.) Pull start with full choke until engine turns over. Then take choke off.
5.) Pull to start.

It should be that easy. If it doesnt start your problems may require a repair shop.

Will not start - brand new

i bought a new dirtbike as a kid n same turned out ,it needed to be a synthedic oil in the mix.try seeing for spark to begin with by putting sparkplug in the wire n touching diode to the engine block while pulling the cord.thats a good starting point to diagnosing your problem.maybe try warming it up in the house then try starting it with no choke needed.the saws i ve used needed you to give it throttle after you pull,n no throttle with choke.
