*Edit x3*
I'm starting to feel REALLY unintelligent! Apparently...heh...you're supposed to depress the throttle to the floor while you're doing the test because it will yield more accurate results. Ergo, higher reading.
Also...not having a super peppy starter (Like you should) also affects this. So I'm wondering exactly how much of a difference this is. I think a little later I will go do the test at least on Grace again with the throttle depressed fully just to see what kind of difference it will make. I don't feel like bothering with the other car because the results are so bad to begin with...

Collin, if you don't open the throttle, you're guaranteed lower numbers. You have to start by compressing a charge from atmospheric pressure. If you start by pulling a vacuum, then it'll read a lot lower. sorry, forgot to mention that. I'd run some seafoam through both, as you're not worried about cats anymore anyway.

Thanks Holly, She is very relieved. Also we excited to start her own practice again like Hawaii.
Ray, Yeah he liked it sooo much he pulled me over. VERY COOL trooper!! I have Never had a run in and been pleased with the outcome. This one actually said.." I hate writing tickets and the associated paperwork"...Huh? You feelin OK ociffer!
He then started asking about the car and what I had done to it. Kept most on the Down low but told him it was all turbo and no gas.( as he asked about a bottle) Then he asked how fast I had ever had it?.... Stu then asked,.." Why, are you going to give us a ticket for that?" Then I said 120 but that was at ZF ON road Atlanta. He just kinda smirked a yeah right look.
We heeded his advice on speed for at least 10 more minutes before we made a friend on I 85....Enter Stu's video
Zach,.. The "mountain meet" is going to take place at my place in Saluda NC. 45 minutes north of Spartanburg on I26. Date is still to be decided and planned out. I will work on that. Everyone let me know what their Thanksgiving on time frame looks like.

Also...I don't know exactly how much I approve of seafoam...could be worth a try. Crit, maybe this weekend if you wanted to come down and spend a day at my mediocre garage. That way, you can check out muh new daughter and help me access the level of work that's REALLY involved.
I might be able to get my dad to hand over one of his Magic Hat beers...they're VERY good!

Just don't plan it the weekend of Dec 13th, I will have to be at work in FL for the PRI Show. I missed the December meet at Ray's house last year, because I was in FL and flight didn't get back on Saturday night until 8PM or so.

hey Ray, what does the Seafoam thing do? and where are you feeding it into the engine? Do you have the idle raised? it sounds like its at like 2,000+rpm...

Zach,
You can either pour it into the carb as it's running, or pull the a vacuum line off your rat's nest or something to deliver seafoam into the engine. It breaks up carbon and frees the seals, though it's not a guaranteed fix, by any means. Lots of folks periodically put it in their gas tank as well. The only caveat to using vacuum lines is that you have to follow the vacuum line back to the source on the engine, as seafoam in the line might only feed one rotor. If so, change your feed point or make sure that you find another one that feeds the other rotor. If you use the vacuum method, you just attach a length of hose and dunk it in the can like a straw. You'll usually want to let it sip in short bursts, though, as it'll likely stumble pretty bad.

Yep, not good for cats. Another good reason to be driving a 12A.
The idle was high because that was the first time I had been able to get the White One running again, after being down for a couple of weeks with what turned out to be several problems operating in parallel.
This was after soaking the engine for a week in sea foam, introduced by pouring about 1/4 bottle down the carb while turning the engine over. This treatment apparently salvaged a side seal, that had become stuck on the front rotor and was giving bad compression.
Another good way to introduce the sea foam while the engine is running is to idle it up to about 1200 rpm, then pour it into the carb until it dies, then let it soak overnight, with a couple of turns of the key to move the engine parts around every few hours. You'll need to pull the plugs and do the unflooding procedure the next day to get it running, but your seals will be happy.
One of the other things I did to try to get it going again was pull the carb and redo its top half, so when I reinstalled it the idle was increased.
Here's the same engine a few hours later after I made some timing and carb adjustments:
And of course here's Jackson drinking a beer:

I usually run it in a vacuum line, and use the line like a hose as Crit said. I dunk it in and take it out, so the engine catches back up, then repeat. When the bottle is about 1/4 full, I dunk it in and choke the engine until it dies. Pour the little left into the carb, and let it sit for 10-15 minutes... or a week like I did once.

BTW, Collin's the guy that was originally asking about it, and he ain't got no cats to worry about (he's got them, just not worried). I should have mentioned it.
It's good stuff, though.

On Sabine, yes. I'm not really worried about them. I was considering gutting them but it'd probably ruin how amazingly quiet the exhaust is. Point blank, I don't want the engine in that car running me around. I may give it to Brett for the low low price of the 'vert's transmission and driveshaft...possibly the diff.

I have been adding a bottle of Sea Foam to the fuel with each oil change. I started this when the car started to not fire on all rotar faces at startup. I ran 2 tanks of gas with Sea Foam through and the problem went away. I was impressed enough to start doing with each oil change. 255k and still runs strong.

I've got cats on Grace? I could've sworn I ditched those sons of bitches...?

BTW, I think you can just pull one of the vacuum lines at the top of the front side of the throttle body, and it would make a perfect spot for the seafoam treatment.
