To set the carburetor on a 1987 Yamaha SRX 540 snowmobile, first ensure the engine is at operating temperature. Adjust the idle speed screw to achieve a stable idle, typically around 1,200 RPM, and then fine-tune the air-fuel mixture screws for optimal performance, usually starting at 1.5 turns out from fully seated. Test the throttle response and make minor adjustments as needed, ensuring there are no bogs or hesitations. Finally, always refer to the specific service manual for detailed specifications and adjustments.

I would say yes. I just picked up a 87 phazer with a 540 in it. Left spark plug boot just rubs under the hood, but it fits and runs.
take off the rewind, under that, there should be a round piece bolted on the end of the flywheel with three bolts, take thos off, under that is the magneto, you'll need a puller to get that off, onvce you do, the stater is right there (it is round and should have copper wound coils on it), there should be a couple bolts holding it on with slots that the whole thing could turn on if the bolts were loose. loosen those bolts, and your timing is the positioning of how much u turn the stator.
