Hey everyone, I just replaced the carp on my 98 Kodiak 400 with PN#4SH-14101-00-00. It starts and idles perfect, but once it’s good and warmed up, it bogs out at 3/4 throttle or more… it sounds like it’s bouncing off a rev limiter haha… I tried the air fuel screw, all the way in and out 2-1/2, and it made it a touch better… tried 2 turns and no different. Am I missing something?

I own a 2007 Polaris Sportsman EFI X2 model and have for the past months been experiencing loads of issues. Basically the Sportsman will only start if the throttle lever is pushed and will not remain on idle. This situation has persisted for months now and I have replaced the following parts:
Sparking Plug
Fuel Injector
Fuel Pump
Fuel Filter
Fuel Valve
Fuel lines
Power Control Module
The last part replaced was the Power Control Module and the Sportsman was tested and worked fine on a couple of occasions which were days apart so much so that some weeks later I took the Sportsman for an extensive ride and it worked perfectly. This was three weeks ago and today I tried to start the ATV it worked fine a few minutes and decided to switch it off so that I could continue with some prep work. A few minutes later tried to start it up again but noticed that it would only start if the throttle lever was pushed and once I removed my finger from the throttle lever the engine would not stay in idle and would simply shut down. Several attempts were made to start this and also tried to re-adjust the setting by turning the built in wheel like mechanism in the throttle cable but it was to no avail.
The above have been repeating itself on an off basis. Each time a part is replaced the ATV would work and then all of a sudden will not keep its idle. At this stage I cannot think of any other solution other than possibly some sensors which might have an intermitting fault but I cannot really say.
Would greatly appreciate any assistance.
Thanks in advance.

Hey guys I have a 99 xpress 300 and I'm having an issue, I rebuilt the engine and it will only start when I put my han over the intake on the car (when I manually choke it), I am not very familiar with plunger chokes.could some one help me understand how this choke is supposed to work and maybe how to ajust it so it works, thanks!

Hello everyone. This is a Go Cart and not a typical "ATV" but it has an engine so I'm hoping someone can help me. It's a Helix FTX with a Manco 150cc engine. The engine will start and idle for awhile, but will not take even a small touch of throttle. Stalls. It seems to take throttle and rev up when you first start it cold, but in just a minute, it will not take any throttle. I've replaced the Fuel valve/Pump on the fuel tank with no joy. It's a nice little cart, but without a workable engine, it's a boat anchor. I'm not dumb when it comes to small engines, but this one has me stumped. I'm running out of options.
I'll mention that while it is idling, it will sort of "cough" every 6 or 8 seconds and then recover and idle again. Eventually one of those "coughs" causes it to stall. It will start back up pretty easily, but as I said, it absolutely will not take any throttle and then it will cough and stall a minute later. I thought it could be timing, but there is no "adjustment" for timing on this engine. I downloaded the user manual and it mentions nothing about timing and is pretty much useless as a service guide. It just shows the basics. I'm attaching the manual so you can get an idea of the machine I'm dealing with.
Any input would be greatly appreciated.
Kind regards,
Don
