I have a 1996 King Quad 300 LT-F4WDX ATV
I tried to install a carburetor rebuild kit but there were no instructions and I am unable to find them. Anybody know what the "Pilot Screw" is set at? The engine starts but seems to be flooding- very difficult to get the rpms up and engine acts flooded.
I set the screw to 3 turns from closed. It is called the "Pilot Screw" on exploded views of the carb.
It is a Mikuni BST 31 single carb.
Thanks for any help!
Hi I have a 2005 yamaha 400 big bear. When I run it without the breather cover on it runs good. This is without the air filter. As soon as I put the lid on and snap it down tight I have no middle or high rpm. Any ideas. I've checked the pipes from the air breather and all are clear. No animals nesting in them.
Picked up this 87 Big Bear from my grandfather. It has been sitting for quite a few years, so I am in the middle of rebuilding the carb and doing other maintenance.
The quad did not come with an air filter, so while I was at the yamaha dealer a new air filter was pretty cheap. Except it was missing something called the element guide. I guess there is some kind of tube the air filter wraps around and sits in the square cutouts inside the air box.
Is there any other manufacturers that make this part? Yamaha wants $60 for the element guide. Worse case scenario I just have to buy it
I was having a bad idle and i found the culprit.
I dont but to my eyes i think that needs cleaned. How should i clean it. I read to use dish soap or landuary detergent. I have also read to use a five gallon full of water and soap but or just enough water with soap to submerge the filter. So how should i clean my air filter
