The cold should not affect the choke. Can you see it - are you certain it is closing all the way?

Starting fluid is a good idea, but don't overdo it. You could also try squirting a bit of gasoline in the carb. I really can't think of any other reason why it shouldn't start at low temperatures, if it starts fine at slightly warmer ones.

It sounds like the choke is not fully closing. You can try a quick shot of carburetor cleaner down the throat of the carb to see if it starts.

Just in case something else is going on, I would use an inline spark tester to verify that you are getting spark when it does not start. I don't think lack of spark is the issue, but it's a quick and easy test that allows you to rule out lack of spark as the problem.

I tried using quick start sometime ago when the problem first appeared. Didn't help. Also mechanic and honda techie told me it would actually do damage if you keep using it.
I called a honda shop yesterday and explained the problem. They advised to get some of their fuel additive that they believe us very unique and failing that to bring in the machine for them to strip the carb, clean it, maybe even replace it, sounds expensive but maybe only thing left.

if it wont start with quick start you have some kind of ignition or valve issue.. maybe when its really cold your valves don't close all the way?

just a rule of thumb... for an engine to run you need fuel, spark and compression.. with quick start its not a fuel problem... if your using a either based product it will light if there's any remote little spark

maybe your low oil shut of switch is acting up when its to cold..??

If it runs fine when its warm its not a carb problem.. fuel wont freeze.. normally... I think gasoline freezes at around -40...

if a Honda dealer charges you more than 80 to properly rebuild a carb there ripping you off.. its seriously takes me 20 min from start to finish.. add a few min if your carb has the electric shut off valve at the bottom of the bowl

Low oil not shutoff working properly is a good idea - well worth checking. They are right that ether should not be used regularly, and never too much at once. But an occasional shot for diagnosis is fine.

I'm not getting a very good feeling about this dealer of yours. It sounds like they may just be throwing parts at the problem (at your expense). You could probably buy a brand new carb for less than they will charge. And I agree with Yellowlister - don't think it would run perfectly at cool temps but not start at all if it just needed a carb rebuild. I would expect it to run poorly anytime.

Maybe there is another small engine place nearby that is well recommended?

The mech at honda showed where the oil sensor cable is and I pulled it off to bypass but this didn't help, so I'm guessing not the problem.
I tend to agree on the ignition problem. I found a YouTube video that shows how to check and replace the ignition module on the pull wheel. I ll try this on the weekend when the weather gets warmer for me to work on it. I also plan to add a battery to the generator since it has electric start already which would also bypass the module.
Temperatures this weekend are supposed to go to 13 deg C which is warm for us at this time of year and will give opportunity to do more work.

Thanx all for staying with me on this frustrating problem.

..like I had mentioned at the beginning of this thread.....Are you getting spark when you have your "no start" condition? Get yourself an ignition tester...they are cheap enough and you can use it down the road on other equipment.

make sure the coil gap between the flywheel is correct.. I use a regular businesses card to gap mine.. don't tell Honda if you do... some techs can be quick to void warrantees...

ive seen plenty of coils not work once warm.. but never one not work when its to cold.. but I suppose it is a possibility..

Might also try disconnecting the shut off switch. maybe it's acting like a bi-metalic switch and closing when it's cold. But getting a spark tester is the first order of business. without knowing if you have spark or not your just frustrating yourself. Of course you could use the freebee spark tester if your brave. stick the shaft of a phillips screwdriver up the spark plug boot into the clip and hold onto the shaft when you pull the rope. if you get zapped good, u got spark. bought me a spark tester back when i was about 12. Can still feel the jolts.

I just hooked up batter cables and battery to use the starter. It's warmer today, around 8. Unfortunately it wouldn't start, tried several times. At least the electric start is saving my arm from pulling.

I assume this eliminates the starter wheel since I am not using it.

Powerking, you mentioned the spark tester, I am not sure what you mean here, excuse my ignorance.
I am guessing, you mean a test using the spark plug boot and holding it to the shaft. When I took the generator to the mechanic the second time, he tried this and didn't get a spark so he said it would be the ignition module. But when I came back to get it, he said he was wrong and it just needed more oil. I never really believed that story but the generator did start and it started again last week when I changed oil, fuel etc. so not sure if this is the problem.

wow.. whats up with your Honda dealer.. u can test the spark by taking the plug out and hooking the plug wire up to the plug and let it sit against the valve cover or something metal and pull it over see if u get a blue spark.

Default Re: Em6500sx won't start in cold weather

I just watched a YouTube video about testing the spark, the person was using a knock off honda generator but looked very similar. I will try it this weekend and if it is the ignition coil, hopefully my dealer can get me a new one.
I am wondering of it is the ignition coil, why would it start once in a while like it did last week a couple of times then stop,again .

It is sounding more like a bad low oil sensor, or possibly a bad ignition switch. Ignition module is possible, but less likely. The Honda dealer is sounding worse.

I don't think it's the oil sensor, I disconnected the sensor cable, it had no effect.
I am puzzled to say the least, since it did start a few times last week after I changed the oil and fuel, that should eliminate many things. But as it is now, back to square one.

Maybe you should start a new thread and see if there's another Stak member close to you who has a bit more knowledge. you might be able to meet up with him/her and they could help you with the diagnostics/repair. look on ebay at spark testers. even if you don't buy one on there, it's a quick reference of the types available

An inline spark tester is a tool you put in series with the spark plug, and watch for a flash (bulb type) or spark (gap type) when you crank the engine. It's the first test I do for a no start, because it quickly gives a go/ no go for the ignition system. Anyone working with engines should have one of each type.

If you tried it with the oil switch disconnected, that should rule that out. It does sound like something loose or making an intermittant connection. I'm afraid your dealer will just start replacing parts, at your expense, hoping to find what is wrong.

BTW, does anyone know for sure that disconnecting the oil pressure sensor on this engine will allow it to start? Is it possible you have to hotwire the switch instead? Robert@Honda, maybe?

Doubtful it has anything to do with Oil Alert, since it does start sometimes. If the oil level were too low, it would never start.

My money is on the choke or carburetor, both of which can be picky about temps and starting (or not).

As mentioned before, the choke on this model is a bit complex, so any one part not working 100% would cause hard starting, especially a cold start.

Caveat: I work for Honda, but the preceding is my opinion alone.

Warm weather here today, unfortunately didn't help, won't start.
As it could be a choke problem, I see no way I can fix it without taking to a specialist. Hope for a quiet winter so I don't need it . Thanx folks.

We've all given you plenty of things to try and look for, like myself and others have mentioned, you need to rule out certain things and be your own "tech" rather than bringing it to a dealer. spark testers should be available at your local auto parts store for a few dollars...get one..and rule out the ignition system
