Working on the wife's sled and running into some problems. I rebuilt the sled last Spring and been have problems with it back firing and only reving out with the choke on half then off. Then it wants to bog. So I changed the plugs and seemed to run better took it out again and she bog off the beginning then go not bad. Brought it back into garage and took plugs out and checked spark onside sparked but other didn't want to. Both sparked before. Thought I could replace the wires but found out quickly they do not unscrew. DUH
So now got to order a new one. I have cleaned carbs twice. Checked the plugs as thought maybe in wrong..Any help be great..
