Fuel in airbox

Matt Kalevich · Posted: Tue Nov 06, 2012 3:12 pm Post subject: Fuel in airbox

Leopard/Tillotson Carb/ KG Cobra Intake
I notice when doing my post track cleanup of the kart, that there is a bit of fuel sitting at the bottom of my KG Cobra Intake and it leaks out the bottom at times. I always open up the intake and clean it. I tend to run the kart rich and conservative and can imagine fuel going into the box, but I am just being cautious to ensure that something is not wrong.
Appreciate the help guys!

yep, i had the same in our leopard, by the way, i was advised by those for more knowledgeable than me to ditch that cobra airbox and run the standard leopard airbox and i did, motor seemed to be more responsive to fine tuning with the standard airbox than with the cobra airbox Smile

Thanks Jeff. Shoot me a PM with the needle settings if you remember. I start both at 1.5 and tune down slowly throughout the day. Just hate getting close to too lean...that and I am still learning a lot on the track.
Also it looks like we arent far from each other if you are in Cocoa. OKC is my home track and live not too far (520/528-Wedgefield). Always trying to meet up and make new track friends! I have yet to see another Leopard at OKC haha

13/4 to 2 on the low, 7/8 on the high

Normal to have a bit of fuel in the box, but, as far as ditching the cobra box, I'm personally not a fan either, but if you resort back to the stock box keep in mind you are losing some air inlet opening. The cobra box has... I don't remember 30mm openings? and the stock leopard box as 28mm? openings or something. I.E. less air, marginally less power to be made.

Also I'd run a filter in the stock box if you run a stock box.

edit: My memory for air inlet openings is crap

You can get the cobra box with either 23mm or 30mm inlets.
