how or when do you effect squish?
take soft sodder take out a spark plug put sodder into the hole roll the engine over measure with a caliper & see what squish you have you might have to do this a couple times to get it most race engines depending on what your doing .040 to top of the piston if you go that far you have to run a higher octane fuel

General Help / Re: Kawasaki Drifter 340 Non Econo-Jet Carb Jetting.
« Last post by sparky55 on November 18, 2018, 05:08:47 PM »
I kind of figured I was close as this carb came from a sled (Ski doo citation 4500) which has just a few more ccs than this one. Iíll give a 250 a shot and see. It was defiantly causing a rich bog as if I let off a little back into mid range it would clear out and run fine again. If I wot again it would eventually load up again. I killed the engine when this happened and the plugs came out jet black. I switched to the 180 jet and the plugs came out a dark gray. Regardless of throttle from about 1/2 to wot. I tried at many positions to see if I could change the needle up or down. Thanks for the advice.

 I agree with mswyka.
I have a 1975 Sno Jet with a 340 fan cooled engine and a single VM-34.
 It would be very similar to the Drifter in HP and RPM and it uses a 250 main jet.

 I then looked in a John Deere manual I have had for years.
 The 340 Trailfire used the same TA-340 A engine as the Drifter, but with a regular (non power jet) VM-34carb
Here is the jetting for sea level to 4000 feet and zero degrees and above:
Main      190
pilot        30
jet needle    6F27-3
needle jet    166-06
cut away      3.0

I was surprised to see the main only 190.
 If your sled was definitely too rich with a 280, you might try around a 250, then "sneak" down from there.
Heck, the 190 may be what you need, but you need to figure out what needle jet and needle you have so you don't run too lean in the mid-range.

In the manual for the 1980, it  lists a 30 pilot, 200 main, and 90 econojet.  Added together that would be 320 total less your 35 pilot would be 285.  So, you must be close with 280.

Hello I am new here. I was given a decent Kawasaki Drifter 340. The original carb ,a vm-32 econo-jet, is beyond repair. Luckily I have a carb (not econo or power jet) from another sled That I was able to install the pilot jet in (35). However I need some help with what main jet to install. The bad carb originally had a 180 main and a 120 econo-jet. The carb I installed has a 280 jet in it that causes the engine to run quite rich. I installed the 180 and it ran 100 times better but, to the spark plugs, puts me in fuel mixture territory that I would rather not be in. Could anyone tell me what main I should install? I would prefer it to be a little on the rich side, but not too much. I ride in between 40 down to 0 degrees Fahrenheit at about 1065 above sea level. Thanks!

Because of the snow our flight to Georgia was cancelled so, since I was home anyway, after I finished plowing I was able to pull the first two sleds out of the barn.  I am pleased to report that they started right up and are ready to go.

The New York Snow Report is... WOW!

Predictions were 1 to 3 and then some rain.  Southern NY picked up about 8 inches and snow is still falling up north.  I am thinking that our season has officially come early.
