Wd-40 question

[96waveraider1100]

HI. Iīd like to know what would be the best way for me to cold start a jet ski after itīs been sitting around for more then two weeks. I thought about spraying wd-40 in the intake to save the battery and the starter( it takes about 2 to 4 min to start it) but I am premixing and I donīt have a primer. Would spraying wd-40 to start it damage the pistons, rings,.......?

Thank you,

David

WD-40 is non flammable.

Get a primer, or pour an oz of premix down each plug hole.

WD-40 IS VERY FLAMMABLE READ THE CAN THE PROPELLANT IS CO2 IT IS NOT FLAMMABLE. BUT THE CONTENTS ARE FLAMMABLE. JUST THOUGHT I WOULD PASS THIS INFO ON SO NO ONE GETS HURT OR BURNED UP.:emoticons

Re: Wd-40 question

Yes, that's true...for matters of using it as starting fluid, it's the propellant that you want to burn though.

Remove the spark plugs and put a couple cc's of fuel and oil mix into each spark plug then reinstall... it should fire right up...

You mean rub some fuel and oil mix around the spark plug or inject it directly into cylinder?

Thanks,

Re: Wd-40 question

Pouring the premix (an ounce is plenty) directly into the spark plug hole will do it. This provides the lubrication you need to start an engine that's been sitting idle.

Having said that, using WD-40 to make sure the top end is lubricated and free before trying to start is a good idea. Nothing like lighting the fire on an engine cylinder that doesn't have any lube at the bottom portion of the cylinder to ruin your day.

By the way, the Seloc manual specifically calls out WD-40 as a starting fluid. Go figure...

Re: Wd-40 question

I find if you remove the flame arrester or carb cover and spray plain old starting fluid in them, they start quickly. If that does not cause them to fire, then there is a bigger problem.

Maybe not the best idea for routine use on a two stroke, but it works every spring on my Evinrude, and every couple months on my pit scooter.....

Annoyingly, the hardest thing I own to start is a B&S lawnmower.

Re: Wd-40 question

Here's what I do: I own a small construction company, so the last time I emptied one of those plastic bottles that holds chalk line chalk, I washed it out, let it dry, and now I keep premixed gas in the bottle. The bottles have those little snap-on caps. I keep it at home (outside the house) close to where I park my ski.

If my ski is hard to start, I squirt a little of this gas into the air intake (mine has a little screw out plastic cap). It fires right up then.

Re: Wd-40 question

when i was younger i used to work at sears in the lawnmower repair shop....every spring you get the mower in for a tune-up with bad gas..well; we would use wd-40 to start the mowers and tractors but we didnt use it on 2 stroke engines (chain saws , weedwackers ect,)because the wd-40 would wash down the gas/oil mixture off the cylinders....wd-40 should not be used to lubricate cylinder walls. leave that job for good old oil.........

Re: Wd-40 question

Several years ago (1998-1999??) WD-40 was re-formulated to use a more "environmentally friendly" propellant, as well as to decrease the volatility of the aerosols....This resulted in WD-40 not being suitable for use to start engines like we used to do with it. I still use it for cleaning many parts on ski's, motorcycles, ATV's, boats, automobiles, and trucks, bicycles....etc...etc...

Re: Wd-40 question

Similar to fallsrider........

If you have the stock FA...Simply pour a little bit of fuel into the hole and off she goes.I do this as a standard practice every outing.I premix,and use a sealable measuring cup for measuring oil....I simply pour about an ounce of fule into my measuring cup....swish it around....pour a little in the hole and start it on trailer.Then put it in the water and off I go.Never had a problem starting this way,and the little extra oil during initial startup helps if anything.
