What NGK spark plug part# 1996 Indy 500 (488)

Hello,

My snowmobile has a stud style resistor plug boot.
There are Champion plugs in it now.
Any NGK part # I find seems to be a solid type not loose or stud.
It calls for BR8ES but they say solid type.
I did find a 5422 that has an arrow decal that I assume means removable tip?

Is this the NGK plug I need for my style plug boot?

Ski doo carbs leaking gas

I’m going to be trying to fix a friends ski doo. It’s a late 90’s 583 with rave valves. It runs ok but it leaks gas out when it is shut off. If I let it sit in my garage overnight it will slowly leak all the gas out. Any suggestions would be greatly appreciated. I’m assuming I need to clean the carbs but would like some input also to make sure my assumption is headed the right way.

Intake Flange - From Tillotson to Mikuni

Hey guys,

On my 1975 340 Olympique I had a Tillotson carburetor and it was great - when it went good! Over the course of the previous winter I learned how to nail it down pretty good with the adjustment. However, every year (for the past 3-4 years) the needle valve gets stuck (as is very common with the tillots) and I'm finding myself taking it apart to clean it.

Anywho, I decided I was going to get a Mikuni carb and the gas cable to go with it. When I went to install it I noticed that the flange bolts were 2¼" for the Tillotson and 3" for the Mikuni center on center. This meant my intake flange (correct me if I have the wrong term here) wasn't the right one. Luckily I had a .343 engine which had a Mikuni on it and the correct flange. I swapped the intake flange but this one did not need a plastic spacer (which in my experience, I've seen crack many of times).

I'd like to get another one like those, I'll attach a picture of it.

Do I have the proper term for this?

Hey dudes and dudettes!

First time poster here on these forums so let me introduce myself. I am 27 years old and have ridden snowmobiles for the better part of my life as my father is a fanatic with vintage sleds. He has a mint 1979 440E Everest that he has completely restored. As for myself, I own a 1975 340 Olympique (.338 engine) and a 1979 340 Olympique (.343 engine). I also acquired a .343 engine a few weeks ago to slap into my '75.

I bought a 75 acre woodlot when I bought my house 4 years ago (they are not on the same properties but fairly close). I love learning about these machines as they are still around - which proves a lot right there!! I'm pretty new to ski doos but I have had a fair share of experience with my Honda TRX300FW.

Will be posting pics once we get enough snow! :) For the time being, here's a pic of my rebuilt slide suspension I am installing on my '75 Oly.

Idle issues

Hello, my sled is a 2002 Polaris 550 classic with a idling issue. I recently took it out of storage for the winter season and tried getting it running but it would not start initially. I tried putting fuel into the cylinders to see if that helped, but it only ran for a few seconds. After many tries to get it started, I put fuel into the carbs and it began to run but would not idle after keeping the throttle open for a few minutes. Then took the sled out for a run to see if opening it up and some fresh fuel would help and it has not. Still will not idle, I do not have a repair manual and was wondering if this has some idling screws or adjustments on the carbs to be able to help this? I did use Seafoam when putting it into storage as well.
