I've been having problems with my Matrix engine from the get go. I've got 1/2 gallon through it and I'm wondering if maybe my plugs are the problem.

I got the [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXABK8&P=7]DuraTrax Racing Plug from Tower Hobbies[/link] and now am second guessing this decision. I want to head up to the local HS at lunch today to get something different. What should I use with the CEN engine that comes with the Matrix.

Also: The manual I got with the car shows an older (I assume) engine. I know the HSN needle is on the top. I am assuming the low range (idle) is with the throttle barrel on the right side and the mid range is the brass looking larger screw on the left side of the engine (easy to get to ) If I'm wrong that would explain quite a few problems, but everything I see on the 'net leads me to believe this.

It has been awhile since I had Nitro and those were planes. But I never had any engine problems with planes. I always had OS engines...maybe that was it.

Thanks for the help !!
