Hey all, happy New Year! Picked up a couple sleds for the kids and am trying to get running but lets only deal with one sled at a time on here.

89 Exciter: good compression, good spark, carbs cleaned today, carbs are getting gas, fresh gas, and new plugs. Sled sputters and reluctantly starts and lights come on for a moment or two with starting fluid sprayed in cylinders after about 4- 8 pulls on rope.

The only thing I may have missed when cleaning the carbs (embarrassing) is I didn't run a wire through the pilot jet to clean, and I didn't pull the pilot air screw to clean. I just forgot to do it. Could that be it?

Grrrr.. please help
 

i would check the choke circuit to,theres a tube that runs down into float bowl and gets gas from a tiny 90degree passage,likes to plug up at the bottom.
 
Took carbs out again and pilots were plugged bad. Cleaned them, cleaned choke circuit again, cleaned out air screws and reinstalled to pre-clean setting, re-cleaned everything else.

Starts easier and faster with starting fluid down the plug holes than before, but won't stay running for more than 4-5 seconds. How many times do I have to do this to get gas back into carbs/bowls to run on its own? Something else wrong?
 
i would use a half capfull of gas and oil down the plug holes instead of starting fluid but that should be plenty long enough to run on its own.fuel pump is working?
 
Okay thanks, I'll give it a whirl. Float bowls are full everytime I take the carbs back off, so I assume fuel pump is working.
 
Most Starting fluid washes the oil off the cylinders of a two stroke. You may by now have the bottom end flooded and exhaust pipe full of gas ? T.O.R.S. ?

I did NOT say that but, yes all the pulling may have caused a bad case of flooding besides, that in fact could actually be the case if the cylinders are washed of oil by the starting fluid and a resulting compression loss could make a no start........

hey i did read it - second time sounded a little better but starting fluid did indeed make my pipes flood..because it washed the oil off the cylinders ,causing compression loss that resulted in pulling too many times !LOL i understand! :sled1:
 
If lights were flickering how about the wiring harness? Have you inspected it looking for breaks or bare wire. Just a place to look.
 
Flywheel rusted, connectors crudy, was old gas still in the line, did you cut back the plug wires a little to get a better connection, ohm out the coil. These should keep you busy for awhile. If they're really crudy, you may have to boil the carbs for an hour or two. They don't always clean up the first time, or the second for that matter.

Good Luk, John
