remove the spark plugs and crank it without starting it and that should clear out the cylinders then clean the plugs with carb cleaner and install them .then start it . it may smoke for a few minutes.
its an awesome skidoo. ive had mine for a few years and no trouble. i am a big polaris fan and i say Indy all the way...i love that skidoo
Pretty sure it was rated at 36 hp.
That size sled runs about 65 to 75 mph.
That was an awesome sled in its time. I have one. It had a powerful and light 340cc liquid cooled Fuji motor. It was the first year Polaris made available modern front suspensions, starting a revolution. It was an option on the 1980 TXL , called TXL INDY. My TXL is the old school, leaf spring model.
You have to buy the conversion kit that changes the hole rear end of the sled and comes with a new track and also a new drive shaft its the only way so i here
79...and they also made one in 2008....it is called the Edge..... there are also some higher cc's like the 550......but my father and i have 2 polaris 340 TX's made in 79'. his is starting to fall apart, but they both still, run....... that and a 73 colt..... we have some older and not working polaris machines but they are in the weeds as we speek....lol All the Indys made had a 340 model.
Not enough, i estimate around 20hp, that is one of the least powerful engines made. save money and buy a 600 or 800.
That motor should be new enough to be running 50/1. Early 70's almost all motors switched to 50/1
1% of 340 = 1% * 340 = 0.01 * 340 = 3.4
25% of 340= 25% * 340= 0.25 * 340= 85
