sr73087 Posted October 7, 2014 Report Posted October 7, 2014 So I have leaking carbs among other issues on the banshee. From my research it looks like it is likely a dirty needle that is possibly causing the needle to not seat properly. What in your experience are the first things to take a look at? Quote
sr73087 Posted October 7, 2014 Author Report Posted October 7, 2014 Typically do most people just rebuild the carb while they are in there? Quote
Starwriter Posted October 7, 2014 Report Posted October 7, 2014 If they've never had new needle and seats put in since you've owned it, chances are that the rubber needle tips are bad. I consider the needle and seat to be a maintenance item. Replace them and be done with it. 1 Quote
ETR174 Posted October 20, 2014 Report Posted October 20, 2014 Either the needle or the float. the float can be set too low and it doesnt seal off the gas inlet. place your carb upside down and with the gasket in place and measuring calipers measure from the gasket on the carb body to the top of the float. Bend the tabs on the float either way so that each little float measures at 21mm. Also the most common way to tell a needle is bad is by looking closely in the light, you may see a ring goings around the tip. That is a major indication that it is bad. Quote

So I took the needle out the other night and found that it was very clean. The needle actually looked to have a rubber tip, which I thought was weird. Anyway, I cleaned what I could, put it back together and it still leaks ALOT out of the overflow. I guess its time to take some measurements and adjust the floats. Also, my choke does not stay out. Is there a simple fix for this? Quote
ETR174 Posted October 30, 2014 Report Posted October 30, 2014 It's not about how clean it is, there should be a visible little ring in it when you look at it under light. Take it apart and take a picture of the tip on the side under a light. Quote
Sandking Posted October 30, 2014 Report Posted October 30, 2014 Just buy 2 new float needles and choke. Set float height and you'll be good for another 5 years plus. Quote

Take it apart and take a picture of the tip on the side under a light. I will pull it apart again in a few hours. The weird thing I noticed is that the tip is made of black rubber, so I may not be able to see anything. Quote

If you're taking them apart again you should already have new parts to reinstall. 1 Quote
ETR174 Posted November 2, 2014 Report Posted November 2, 2014 Not all carbs have rubber tipped needles. I assembled the carb on my DT125E and the needle is all steel, even the tip. Quote
