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.
changing it up a little from the ol grizzlys! In this video we snorkel a Honda with Travis's N2Deep snorkel kit! If anyone wants to tackle a snorkel install or get me and Jon to install it they can save 10% on the N2deep website with the code ODMM10.

PLEASE HELP !!!
hey so never ran into this before but i recently got a 04 honda rubicon 500. bought it from my doctor not running and the front brakes were locked up. cleaned the carb and it fired right up and runs great. these model atvs have drum brakes front and rear. not a fan. lost all brakes on this one when i hit some water and it got inside the rear drum case. so i ordered new shoes for the rear end no biggie. front is more complicated. has hydraulic drum brakes not sure who thought that was a good idea but the pistons in the drums rusted and locked up from it sitting with moisture in the drums.
so i had a choice to make- 1. buy new brake pistons ($120 for a set of 4) or 2. order super atv's disc brake conversion kit for $250. i HATE drum brakes so i went with the conversion kit. it said it was easy to install with no specialty tools. so i order it and turns out i have to press the studs out of my hubs to get the disc on.
anyone ever done this and if so how?
I have a DS 650x available. Garage kept for its entire life and runs well. OMF beadlocked wheels. Located in San Antonio Texas area. I’m motivated to sell and work with shipping options but serious inquiries only interested in a large sport ATV that won’t come around again.
Here’s a photo from a few weeks ago. I can send over more photos, videos, or we can have a FaceTime session to take a look remotely. Let me know.
