The play on my KQ 300 (1998) choke doesn't allow for the full movement downward on the thumb lever. So it goes about halfway down and if I push a little too far the cable pops out of the plastic setting it sits inside of. Then of course I have to take the control unit apart and put it back into position.
Is it normal for the thumb lever to not go all the way down?
I have no play left in the adjustment screw on the cable in the correct direction. The only play I have left would make it worse.
It'a a new-to-me quad so I'm not sure if it's a replacement cable or OEM.
Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.
It's been a while since I posted. Fan trouble and the replacement I sourced on amazon is still working great on my 2005 Suzuki KQ700.
Unfortunately this year I lost my outdoor best friend. He's that go to guy for everything … the day run, may walleye opener, last minute hey my boat's at work get your a$$ over here with your rod and let's go kinda buddy. I bought the quad last year in March and with him gave it the once over and prepped it for fall hunting season, but cancer took him before we could enjoy this new aspect of outdoor life. We planned an October trip into the bush with our quads guns and tent trailer. It never happened. A tribute to our fallen and lost.... But in their memory take the opportunity to grasp every minute of the outdoors you can, life is short... you can sleep at the end...
I've curious what everyone has been doing to prep for the spring season. I mounted my battery and the quad started up straight and easy, just powered it up once or twice to juice the injectors and it fired up after a couple of seconds. I let it run, confirmed fan started, checked charge voltage. all good. I did all my oils in the fall to make sure no water was present anywhere so skipped that this spring.
So what have I done over the winter to prep for quadding? I've been researching. This year I am going to cross over quading with brook trout fishing. So I have been pouring over my old maps from my youth, google maps... looking for those faint markings of trails I can't travel in my F150 (well not yet, paint still looks pretty good ).

Hey, working on my gf's lil dvx250 which needed the carb cleaned. Like an idiot I removed the bracket that holds the choke lever on and the spring that was behind it that I hadn't seen popped off. Anyone have a clue how it goes back on? The manual pics dont show it and I had no luck on YouTube! Thanks!

I know...I feel stupid for asking. I find it impossible to use the thumb throttle with my thumb when I have the bars turned full right. I have to reach across the top and grab the throttle from the front with my fingers. It isn't very smooth and I can't help but think that there must be a technique, mod or adjustment for this. How do I get past this?
