How did it run?

Looks pretty good, I would pull 2* more out and run it .... bet it doesnt slow it down.
I dont like seeing the timing mark on an NGK plug. The fuel looks close but its hard to tell in the pics.

i think you better not try to reuse that plug.
























looks pretty good to me. i think timming is close, but pull 2* as stated, if it does slow it down, i would not worry about it and put the 2* back in.

but seriosly, i wouldnt try to reuse that plug. lol,

it hit hard and was very smooth through the whole pull. i will back out the timing to 23 degrees and do another pull tonight. i tried cuttting the plug with a dremal and it was a pain in the ***. should i just break out the good ol hack saw?

third gear pull on a closed track. i pulled over, put a fresh plug in, made a 3rd gear pull, shut her down and pulled the plug on the side of the road. she hooked since i was on slicks and i had it come on at 4k.

number 3. its the easiest one for me to get to. i know 7 is usually the leanest, but i dont think i can pull it without getting burned even with gloves.

Take the other 3* out and go down 2 on the fuel jet.

We need to see 7 or 8 sooner or later.
If 3 is showing that much timing 7-8 may be a good bit to much.

Sounds about right.

Is the test road long enough to get maybe 2nd and 3rd or 3rd and 4th?
I'm thinking you arent getting enough color because of the short run time.

Pull 3 and 8 so you can see the difference.

i have been using my ten pound bottle for the testing, do you think putting my 15 lb bottle with my nano will lean it out enough as to not adjust the fuel pressure?
