Ok so last week my dad and I MANGED to get the snowmobile start! the choke it broken off but we used some Vice grips to hold it open and we pulled on the Cord about twenty times with the choke ALL the way on and each pull it started more and more. but It wouldn't rev up after the twenty time of pulling the cord the snowmobile ran for about five seconds with the throttle ALL THE WAY open and the choke on then it died so he pulled it again then it ran for about ten seconds this time then my dad let go of the throttle and it start to die so he pulled the throttle all the way open and it wasn't revving at all it would just Idle
So we took the carburetor off and open it up. IT WAS CLEAN! And the float system in it was AMAZING!!!!!!!
My dad thinks the Fuel Filter is dirty
and that's why the snowmobile won’t start we also found out the Throttle cable is a bit frayed but just slightly so were ordering new parts.
I want to make sure though. Do any of you think the main issue is the Fuel Filter
We put brand new gas in it drained the carburetor and crank case so there is new Gas in it.
And also the Spark plugs in it weren't BR9ES Spark Plugs they were BR8ES Spark Plugs
My dad had the originals in it but he switched them around with BR8ES Spark Plugs when it was last running about five years ago.
Here's a parts list of SOME of the parts for his exact Snowmobile
