New to the sight I'm trying to fix a buddies polaris 425 2×4 magnum 1995 this 4wheeler has sat for a few years but ran fine when parked cleaned the tank and lines fuel pump got to the carb torn down soaked for a couple of days cleaned all parts with carb cleaner and used a air hose to dry put carb back together motor starts right up but boogs down as I apply throttle I've been back into the carb a few more times with the same result if anyone can point me in the right direction would be much appreciated

 

Do you have the air box and filter back on? If not they wont take throttle unless you do.

 

I do indeed its all back together and complete

 

If you still have the foam support collar make sure it's not blocking air flow.

Should have a steady pulse of fuel from the pump. Not a fan of just cleaning carbs as that doesn't always help.

This was one of the models affected by soft heat treatment on cams. I saw that it was supposed to be running good when it was put up for 2 years,but I've heard that before also.. Just the old negative mechanic in me I guess

 

No foam on filter and I'll check the fuel line I just got off line ordered a new fuel pump and carb kit I'll keep in touch let ya know this all works out
Thank you
