Teamline B7s ROCK!
It's a little different to tune than Nova based engines. The thing with the B7 is that you must get it up to full operating temparatures before trying to tune for power. A whole bunch of us up here in Canada run the TLB7 and we run them with cold plugs like ODO99, MC#9, NR#5 etc. And we found that we must fully saturate the engine and chassis with heat befoe trying to tune. If you try and lean it before it gets up to full temp, the engine will lean out when it warms up and get really hot. Whereas with Nova based engines you can just start 'em up on the 'box let 'em warm up a little bit and tweak the needles until it screams then get the last 5% on the track.
When starting from cold, it should stall a couple of times because it's running a bit rich. Warm it up really well on the starter box to help get through this stage. Get it out on the track and run it for a couplafew laps. You'll notice it start to get faster as it heats up and burns more fuel. If engine still runs rich, lean 'er out one hour and run a couple of more laps. Go in 1-hour increments.
Anyways, run cold plugs, run it rich when cold, and let it get up to full temp on the track before turning any screws. Once you get used to running the Teamline you'll love it as I and many others around here do! People who run V-Specs would also love this engine. Same kind of engine. And the B3 is no slouch either! People give them no respect until they see one run!
You won't regret buying a Teamline B7! They're awesome!
