Spitting and Gurgling

[sinesthezia]

Started up the buggy this morning. To my dismay it was spitting fuel out of the exhaust and making gurgling sounds. I adjusted the high-speed needle, to make it more lean, and that still didn't help.
I am very new at this so I don't know what else I could do to trouble-shoot this issue.

Please help!

This car has given me nothing but trouble. Or maybe it is just me =/

Ok.. to start what kind of engine is it; Brand/size? Is it broken in yet? How much fuel has been put through it? What type of fuel do you use....% nitro? For me if it is that rich....spitting out of the pipe it still needs to be leaned out some. Let us know a bit more and we would be very happy to help out. Don't worry we were all new at it once and it can be a big PITA at time but it pays off

The car is a Raze Buggy. The engine is a Supertigre G-27CX .27.
It was broken in back in august and I have run about 10-15 tanks through it already. I am using 25% nitro fuel.

Hope this helps

If it's spitting out that much, I'm guessing you can't get it up to speed. If thats right, you need to lean the LSN and adjust the idle first. Little by little. You might need to adjust the HSN also at this point to get everything 'balanced.'
Once you have a good idle and takeoff, let it come up to temp and start adjusting your HSN for WOT.
Keep us posted.

We recently added a sticky on top of the General Nitro forum that will give you a flow chart for tuning. You can print it and keep it with you for reference. It's VERY helpful as far as tuning issues.
