Need help, my sled won't start...

My '80 Mirage 2 with the 377 refuses to start. I have spark and fuel, but it doesn't even sound like it wants to start. It started on the first pull yesterday, but stalled out after about 10 seconds. That happened 3 times, until it wouldn't start anymore. It sounded like a fuel issue, so with that in mind I found the awesome help page on here, and with that I took apart the carb for cleaning. The pilot jet was clogged solid, but after some tedious work it's now nice and clean, along with the rest of the carb. Had high hopes this morning after putting her all back together, but still nothing Anybody have any ideas that may help me?

check your tube from the tank, it might be clogged also

What does your spark plug look like? Is it wet? Your engine might just be flooded.

The tube is new, but I just checked it and it's clear.

The plugs were wet after about 15 pulls this morning, so i cleaned them up real good. After putting them back in I tried a small shot of starting fluid in the carb and still nothing....this is driving me nuts

Starting fluid???

First off, you shouldn't need starting fluid. Before putting your plugs back in, did you check if you had spark? Next, I had a similar problem with my Élan on Friday, I noticed that the plug was wet but also had little beeds of water on them (condensation in the gas tank). I emptied what little gas I had left in the gas tank and put some fresh gas back in and everything ran great after I bled the lines.

Yeah, I know the starting fluid wasn't needed, but I was at my wits end and wanted to hear it at least cough a little. I had good spark from both plugs before I put them back in....and definitely no condensation on either one. What else could it be?

swap out the plugs with a fresh set. they might not be willing to fire under compressoion after being flooded.

I have the exact same problem on my 96 polaris xlt. I also used starting fluid out of frustration. there are bolts just at the bottom end of the crankcase that allow you to drain fuel. I undid them and fuel dumped out....still won't start though. I would be interested to hear how this turns out.

I'm with MNJoe loads of times a sled won't start on plugs that were wet and will with dry ones. Once you get the sled running swap the plugs back and the "bad" ones will burn off whatever was making the sled not start and be okay again. Cleaning them with brake cleaner or burning them with a torch will help too.

Occasionally on a difficult sled I've heated the plug tips with a torch, I dunno if it really helps, its a really common trick for the British motorcycle crowd I'm told.

You might also have somebody hold the throttle wide open while you pull the engine over. Careful of course.

Just got in about 5 minutes ago. Had fuel off, drained fuel from crankcase, put torch in jugs big BANG, pulled about 8 times with kill switch on, heated plugs, put them back in....turned fuel on, throttle pinned...no go. pulled X 10 got it to fire once....ran then died. Did it all over again...no go. Spit on it again...kicked it...and got back on the computer. LMAO..... Oh yeah...i finally ate right through the rope guide cause I've pulled so many times since Saturday. Can anyone recommend a shop other than a dealer to get this POO going again?

Ive torched the ends of the plugs before as well, but have also runa bit of sandpaper through the gap to clean the metal surfaces of the electrodes.

be careful with lighting off the jugs. There is a remote chance of the fuel -air mixutre in the crankcase being just right and lighting off unexpectedly. Then a nonstarting motor would be the least of your worries. Think shrapnel!

I say again, pony up for a fresh set of plugs....

I'll pickup some plugs tomorrow. ok....so i'll take my old plugs out. Pull a bunch of times....drain the crankcase, then put the fresh plugs in. Do i choke and give throttle? or just choke?? or just throttle? Its about -32' celcius right now. Thanks for the tip about the jugs...last time i'm doing that.....my ears are actually still ringing

Ignition off and throttle wide open.

If you light the jugs DO NOT pull the sled over, that gets air in there and blammo for sure.

I'd say turn the gas OFF, throttle wide open, plugs out, ignition off, pull until you're tired. Take a rest, plugs in the caps laying on the engine (like testing for spark), ignition on, pull 5-10 more times. Then plugs in, 5-10 more times at which point it might pop. Then gas on, 5 more times NO CHOKE! With luck it'll run at that point, if not check the plugs. If they're wet replace the needles and make sure the floats float.
