Compression on 2000 polaris 250 trailblazer

I have a hard starting engine and am wondering if 90psi for my compression is the cause. I seem to have good spark and fuel. I put in new plug and new fuel and cleaned the carb thouroughly so we can rule those out. Any suggestions are more than welcome thanks

The fuel could be good but still it wont spit check the carbs when you throttle or kick start if thats possible if that is good try some starting fluid it should start up and the fuel pump should get out the obstruction if theres more problems it is one of many things either bad fuel pump, your fuel line is disconnected, blown headgasket idk the psi specs for the 250 but that sounds good i know for the 550s its around 120 and so on

SOURCE: my 2002 polaris trailblazer wont start it has fire

If you have oil and gas and it will fire then try a new plug. A bad plug when removed will appear to be fine but under compression can fail.

Also try a splash of good gas in the throat of the carb or intake (if fuel injected) with a new spark plug. My bet is it fires just fine.

If this is a fuel injector type engine you could have a bad injector control unit or a clogged injector.

If it fires with gas in the intake manifold then suspect carb or injector system. (which ever applies)

Thanks for using FixYa!

My 1999 Polaris 250 trailblazer has no spark please help


Probably the ECM, if you have a good, charged battery, spark plug, wiring is not damaged, and kill switches are in "run".

I have,a polaris trailblazer 250. I had to pull start it because it seemed the battery was bad. Bought and installed a new battery and,still won't start. Any ideas....


If it will not spin over, check for battery voltage to the starter.If there is 12 volt to the battery connection on the starter while the start button is being pressed then the starter has gone bad. If there is not any voltage to the starter while pressing the start button, check for blown fuses and the starter solenoid,usually under the seat near the battery, and starter relay,also near the battery.

Where is compression release for polaris sportsman 4x4 atv


Polaris uses an automatic decompression that sits in the exhaust cam. There is not an external lever as there is on older Kawasaki's and dirtbikes. What seems to be the issue as to why you're looking for a compression release?

I have a 2003 polaris trailblazer 400. the oiler stopped working and fouled up my piston. I got it rebored and new piston. after that job was done i tried to start it. would not start. found that i had no...


fyi, something to watch out for on those is bad crank seals. will allow a lot of air in and cause the engine self destruct. before the cdi try simpler things like coil and making sure all the wiring is right. good pickup coil.

1998 Polaris Explorer 300. Could you please tell me what the compression reading should be? I turns over but wont start, will start if boosted but dies out when you let off the gas. Before all this started...


Hey Ang,
Just from what you have told us... this seems a little more complicated than simple... Does it only run wide open? ...Has anyone been "working" on this atv...?? IF they have been working on the carb, you may have put the slide in incorrectly...there is a groove down the side of the slide and a pin in the carb the groove runs on...
1. Compression should be 120PSI...or more, with the the throttle held wide open and kicked over 5-8 times.. The carb may need to be professionally cleaned and set...(take it to a qualified professional)...do this and reply to me..
