<p>Thanks for your replies. I usually check my plugs in the reflection in my knockoffs from the light from a Coleman lantern. My current needle supplier has not suggested anything other than the RH, usually he has a plethora of suggestions.

<p>I didn't build the engine but it has an advertised compression ratio north of 10:1. It has an Isky cam with the number at home in the file. Previous owner ran an couple of races at altitude (+- 5000 ft.) and one Kastner Cup down at about 800 ft..................................................................................................................................................................................with
the SM needles.</p>
<p><br>
</p>
<p>I plopped the RH needles in at Blackhawk and it still looked lean. Hopefully I haven't done any damage.</p>

</p>
<p>Bruce pulled well up above 5000 revs, I didn't dare venture up to 6000, but he felt like he would go there no problem.
</p>
<p><br>
</p>
<p>I'll be at Road America with at least as many needles as spare spokes......................</p>

I think my engine wants more gas than is being<br>
supplied by the RH needles. Anyone used another<br>
standard needle to accomplish this? The carburetors<br>
are the H6. <br>
<br>
