90 indy 500 newb
new to snowmobiles, new here.
bought 90 indy 500 from my dads buddy has 2600 miles, sat since 01. Tank was drained, plugs changed and idle was erratic, had to feather throttle. i got her home and cleaned the carbs and put new bowl gaskets in as they were shot and pilot jet was clogged the idle was high afterwards. put some carb cleaner at the pto seal and it reved, then the seal spring came out. so now i'm gonna fix that when the clymers shows up. my question is is the anything i should do besides when the case is open? was gonna pull the engine and just do the bottom or should i rering the pistons? i have heard the crank bearings could use an upgrade in oiling ports? may sound bad but lookin for the cheapest yet most reliable route. got a buddy that used to work a sled shop thats helpin but all i get is sell and get a cat, only paid 100$ so that aint an option. any tools i may need besides clutch puller? it runs like a raped ape when i got it going but havent got compression numbers yet, only like an hour maybe of run time with the lean condition. thanks ahead of time josh
