I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.
Hows evryone feel about blasting around in snow ?
I love it usually after all plowing is done ill drop the plow and just go lut and have fun. From drifting all over lol to packing snow trails in woods its fun , never been into snow mobiles , where we live its very rural and our roads seem like an afterthought when it comes to plowing lol , usually last to get cleared , so we will hit the back roads to powerlknes and such , we have several people around here with side by siedes ,and the usually hit the powerlines , pack the trails and then we hit them good fun ....Anybody else ?

Below is a quote from a response to similar question from yesterday:
"Easiest thing to check is trash in the main jet. if it idles fine, then the idle circuit and low speed jet is clear. if it bogs off idle that's when it's transitioning to the main jet."
I will go ahead and open up the carb and check the main jet, but please respond to this post as if the main jet is squeaky clean.
Below is my post:
Only starts and runs on Full chock.
Does not matter what position I have my "mixture" screw. Tried it at zero, 1 turn, 2 turn, up to five turns. Spent a few hours confirming that the position of the mixture screw does not resolve issue.
Runs great at idle and if I slowly engage throttle, it will rev up as expected. But, quick rev up or when I am trying to drive it, it spits and sputters and looses power.
I also use a propane bottle and did not find any obvious leaks, and the vacuum port is hooked to fuel peacock and I also made sure to simply block the port with my finger to see if that would resolve the issue.
New Carb (after market), New Coil, Fresh Gas. No leaks at manifold boot, hot battery. Good gas flow. Runs too good to be a valve issue, or cylinder, great compression.
I can move the choke out a tiny bit, and it will still run, but will still bog down when I try to power it up.
I also have a 250 trail boss Polaris that I require to run at full choke, but it has power at all throttle potions.
I suspect it is running rich as the choke is on, but will not run with it off.
Any details would be appreciated.
picked up this pos bike for $80 not running. took it home, cleaned the carb and bypassed the fuse- ran great (other than the rev limiter- those things are so stupid) Then one day out of the blue it starts flooding on cold startup and wont idle cold, but idles to fast warm. (too fast being about half throttle speed heh). I tried a new carb ($10) and new sp. new carb wouldnt make it run except on choke and then it was gushing white smoke. I had better things to do with my time so I parked it in a shed and used it for a work bench for a while... this last weekend, I wanted to take it along with the sportman to a mens retreat to let the younger boys have some fun on it-- took about 30mins to pull all the crap I had accumulated on it and then rolled it down to my workshop, put the old carb back on after adjusting the needle clip up two notches (leaner) and threw it back on the bike. Will turn over, but no fire. I didnt have time to check sp that day but just wanted some incite on what could be wrong with this quad (if it even qualifies as being called that)
