Yes it was, I'm getting use to it, just had it towed home that past Monday for the the trans line coming offing and the trans shutting down.

I was worried when I drain the oil and it was a little milky, but I flushed to good and the oil pressure seem good, so I got lucky

TR-6's gapped @ .035, NX wet on a rich 150 shot ( I used the 35F instead of 33F with 62N)

I'm not sure of my A/F stock fuel table with 25-26* on 92 octane, I'm sticking with 23* from now on

the plug melted, was it black white? did just the electrod melt? your wet kit is a single nozzle?

i would recomend a leak down on the motor, but thats your call. depending on how bad it melted.

how old are your injectors? have you ever had them flow matched? cleaned?
sounds to me like you may need more octain or less timming. but it could be other issues.

The engine and plugs were too hot.
You probably had too much fuel too.

Maybe you had hot-lapped it and are still running a tstat.

Someone told me to check the fuel solenoid, before runs the car is around 140* at the end of the run it's 180-185* (I'm running a 160 T-stat with an extra hole drilled)

I'm going to check the fuel solenoid, check the fuel pressure, change the fuel filter, run some injector cleaner.

I also have a hot wire kit I need to install, but haven't got around to

The injectors were used, so I'me not really sure how many miles.

I changed the conveter because the Yank SS4000 was to loose for me daily driving.

Did I answer everything?

You did pretty good for one reply for many questions ( I think thats a first for you). Did I mention to you I see no difference in ET/MPH running 24* compared to 28*? I ran the 24* on the one halfassed run with both stages, no KR, no lean spots, it all looked good. Might be hotwire helping, but the shot size your running shouldnt REQUIRE the hotwire kit.
