Hey guys, back again this year still trying to get my 77skidoo. everest 340 going. I cant get it running at all. Tons of spark, freshly cleaned carb new plugs. Pull and pull get nothing but wet plugs and fuel coming out the exhaust. Where do i start? Replaced points last year and got it going then it just kept flooding out. Thanks for any help

Spark, fuel and compression and it will run.

Spark present and fuel running out of the exhaust would make me start with the carbs.

We had 69-73 ski-doo's growing up - not as familiar with the 77. Is it still using the Tillitson carbs the like the older ones? We would have to completely rebuild them EVERY fall - new gaskets, diaphragm and needle valves. If the rubber tip of the needle has even the slightest indentation left on it when you pull it out replace it.

Good Luck!

Yeah it runs a tillitson 148b. I rebuilt it last year and had it running one time, shut it down and wasnt able to start it again. Cleaned it the other day, everything still like new. Just doesnt want to start.

Yeah - with ours it didn't matter how well we cleaned them. Every fall they needed a new rebuild kit. We would clean and clean and clean and spend hours trying to get it to start - wouldn't start. New rebuild kit in the carbs and they would start right up. I don't know what it was about those carbs - I was glad to see the last of them!!!

Also check the compression...
