Well when it’s warmed up and idling with airbox on adjust idle air screw slowly and pay close attention to when engine runs best or the fastest. Then find out how many turns it goes in. I think if it’s 1 1/2 open you can get a fatter pilot jet

I always use a small screwdriver and my finger to measure depth of choke bore and adjust choke cable to match. Then when installed and tightened and gauge pod down the lever should have a little free play. Are you using full choke or just first or half on position?

Hi everyone, I’m sort of new on here and do not know anyone. I like all the knowledge you all have. I was wondering if anyone has used millennium technologies for crank and cylinder work? I’m trying to get a couple of 80 sportfire sleds going. I would like to get cylinders done and see if I can get ...

Thanks Dustin!!

Ok sounds good, thanks for your help. Have a great new year. Let me know you get payment.

Ok so so two bottom middle brackets and shroud $90? Do brackets come with wheels?

Well What would you want for a bottom bracket? I’ll weld tabs onto my rear arm if I can get the shaft out

Well the bracket that would hold the missing bottom idler is broke off, I stuck a bolt in it to hold together for a test fit.

image.jpg This is what I have, the painted one is for old cleated track which doesn’t fit of course. The other fits but is missing the one bracket and bottom idler. I don’t know what it came out of, assuming it was newer sport or liquid and not sure why it doesn’t have the idlers on rear frame. My ...
