snowmobile help???

i have a 1989 skidoo mach 1 with a 583 rotax motor in it. it ran fine the other day and now its not getting gas? i have tried heating it up with tarp over it heater under that and snow at the bottom to keep the cold out and i must say it warmed up great. but still not getting gas. the carbs where just clean a couple months ago. so that couldnt be the proplem. has over a tank of gas. and also has i put some gas line anti freze in there. Any one have any ideas?

Does it have a fuel filter?

If so, maybe that’s plugged?

Or if it has a fuel pump maybe that’s not working?

No too familiar with that model

Fuel shut off valve on or off?

Key on? Stop switch pulled up?

Kill button up and fuel is on. never thought of the fuel pump or filter.

as bad as the gas is now days, and just having to put another carb kit in my atv after less than a year, i am going with a carb that needs some love.

dumb question but… do you have spark ?

has spark it runs for a while if u put gas in it the park plug hole lol

take the fuel line off the carb/carbs fuel filter and turn it over quickly and see if you get fuel ,if not fuel pump bad or vacuum line bad to pump if it is that style.

Pulse line from crank case to fuel pump, fuel pump diaphragm, fuel filter, fuel shut off valve, fuel pickup in tank, fuel pickup hose in tank. Cleaned carb could be the culprit if not properly reassembled. Just replaced all fuel lines on my 95′ and vintage 76′ Jags, the lines were rock hard and crumbling.

Check the line in the tank! Common for them to rot and fall off in the tank.
