rjg854 11,710 #2 Posted November 20, 2019 Not sure how to say it, overkill, to powerful, very explosive. Try carb cleaner as an alternative 2 1 Share this post Link to post Share on other sites

gsummers 236 #4 Posted November 20, 2019 I have heard that it washes the oil off of piston and rings, not good. I always use carb cleaner when needed, has a little more lubricants in it. Share this post Link to post Share on other sites

If I have an engine that needs it .... It doesn't need it. It needs repair. No excuses. And it gets flippin COLD up here so we have some nasty temperamental engines sometimes. If it don't start with its own fuel system the fuel system gets fixed. 3 1 Share this post Link to post Share on other sites

The Tuul Crib 7,338 #7 Posted November 20, 2019 I've always used a little gas in a spray bottle. A couple of sprays down the throat of the carburetor with this is a lot better than using starter fluid or carburetor cleaner . 3 1 Share this post Link to post Share on other sites

Mike'sHorseBarn 3,055 #12 Posted November 20, 2019 I know taryl on his youtube channel will tell you that a little starter fluid or carb cleaner to get an engine going will never hurt it. As long as you don't run them for long periods of time on that kind of stuff you'll be fine. I've used carb cleaner a lot to get an engine that has been sitting a long time kick started. My trailer queens do a lot of sitting around and the need sticks to the seat as a result. If tapping the bowl doesn't free it then spray a little carb cleaner in the throat of the carb and the vibration of the engine running will free it up. Y'all do what you want but I don't worry about doing it, but I do know I sure as heck will be trying WD-40 now! 2 Share this post Link to post Share on other sites

Learning stuff today WD40 also kills weeds I'm so old I can remember when WD-40 didn't exist or when LPS 3 (or whatever) was almost as popular as WD-40 (LPS 3 much better for many applications) Lubriplate the real deal - but distribution limited ... fortunate if you could find it at the local parts store Share this post Link to post Share on other sites
troutbum70 857 #14 Posted November 20, 2019 I have found the best use for starting fluid is when trying set the bead on tires with stiff sidewalls and you don't have a ratchet strap or similar handy. My kohler kt17 if it sits for a long period of time can be a bear to start and it will not fire on wd40, have to give it a little carb cleaner to get fire in the hole. 1 Share this post Link to post Share on other sites
wallfish 17,193 #15 Posted November 20, 2019 (edited) Surprising! If you "Just fix it" guys want to tear down a $10 old briggs vertical shaft lawnmower engine to fix it before knowing if it even has spark, have at it. I'll just spray my crap in and give it pull to see if it runs and know instantly. Shooting a quick shot can most likely indicate if the problem with an engine that's not firing is fuel or spark related, as if it fires up, it's a fuel problem because it has spark. Saves time. It's also helpful for old pull start engines that sit for long periods and have a little trouble starting back up. Some use the vacuum of the carb to pull up the fuel and just need a little bump sometimes or you can yank that thing for 10 minutes until it goes. I'll give it quick shot instead of pulling and be on my way. I typically use carb cleaner since there always a can around. Modern starting fluid is no where near as explosive as the old ether was. You can barely set the bead with half a can now. Before it was a couple of quick sprays and stand back Edited November 20, 2019 by wallfish 13 Share this post Link to post Share on other sites
tractor guy 3 #16 Posted November 20, 2019 Starting fluid is a volatile, flammable liquid which is used to aid the starting of internal combustion engines, especially during cold weather or in engines that are difficult to start using conventional starting procedures. It is typically available in an aerosol spray can, and may sometimes be used for starting direct injected diesel engines or lean burn spark engines running on alcohol fuel. Some modern starting fluid products contain mostly volatile hydrocarbons such as heptane, (the main component of natural gasoline) with a small portion of diethyl ether, and carbon dioxide (as a propellant). Some formulations contain butane or propane as both propellant and starting fuel. Historically, Diethyl ether, with a small amount of oil, a trace amount of a stabilizer and a hydrocarbon propellant has been used to help start internal combustion engines because of its low 160 °C (320 °F) autoignition temperature. Use any flammable liquids very carefully or you can get hurt....if you spray to much, it ignites will be a big fire ball.... if you know the problem, fix the problem or get some one with skills to fix it... 2 1 Share this post Link to post Share on other sites

Stepney 2,335 #18 Posted November 20, 2019 I very well recall a tale an old timer told me a long time ago. A large hit and miss engine was being started on ether. Blew the head and cylinder to bits. As a kid I holed a piston on a small Kohler in a generic riding mower. Didn't take much.. I concur. I haven't had ether around in years. I do keep a little pump oilcan full of mixed oil/gas for the occasional stubborn engine that may have been sitting. They weren't stubborn and fickle when they were new. No reason for them to be now. As for the 'free curbside mower in unknown condition'. Thats what the oil/gas mix in a can is for. A little oil for dry rings and still plenty enough kick to see the engine fire. Maybe I'll add some little brass priming cups to the heads of my Kohlers .. yknow, like my one lunger engines have 1 Share this post Link to post Share on other sites
Tractorhead 9,065 #19 Posted November 20, 2019 I agree with some, if an Engine needs a starter fluid, fix it. independently of the Age, an engine must be able to start with it‘s own Fuelsystem, if it doesn‘t something in the envoirement must be wrong. that can start from wrong engine oil, come over worse ignition and last but not least wron Fuelsystem. i dove several older Engines over the time, but never need stuff like that, even on very old Diesels. the only alternatives i accept at very cold day‘s was a preheat of starting air on very cold day‘s.. depending on your possibilities, i would use an old hairdryer or a small torchburner to preheat the Air arround purifier while try starting. If oil is too cold and crankspeed cannot reached (mainly on older diesels) starter fluid will be the quick engine killer. change oil to a other viscosity and the engine must start from itself. max. A warm breze to airintake to help starting. best will be on Watercooled Engines a water preheater. no cold start and immediately a warm car. 😎 1 Share this post Link to post Share on other sites
JoeM 7,886 #20 Posted November 20, 2019 I use WD40, but you have to buy the one that is flammable. I am with EB though, when they are right I never had any cold start issues. The only time I use anything to start is for troubleshooting. 1 Share this post Link to post Share on other sites
Mikey the Monkey 697 #21 Posted November 20, 2019 i use it occasionally if i have a new tractor to see if it has spark/fuel. i used it this past weekend on a snowmobile. before i use it i always have to tell myself im ok with the possible outcome of using this...it might make me lazy or careless i dont know, after all its a lawn mower not the space shuttle...easier than pulling my shoulder out of socket on an old snowmobile 3 Share this post Link to post Share on other sites
Pullstart 63,529 #22 Posted November 20, 2019 The other day I pulled my C-160 out, popped in a battery and it rolled over. I shot a spray of the juice in and touched it off. It was a great quick way to tell if I needed real tools like a meter or points file. Lazy? Yep. Quickest alternative to see if it’s worth digging in to? Yep. 5 1 Share this post Link to post Share on other sites
953 nut 56,742 #23 Posted November 20, 2019 I have used starting fluid on occasion to encourage a dormant engine to cooperate and have never had a problem with it. As with most other things in life, moderation is the key to success. If you drench the cylinder with starting fluid you are going to have a problem. 9 hours ago, tom2p said: WD40 will solve world hunger ... ... poverty WD40 and duct tape BALING WIRE, you left out baling wire!
