everyone knows, I NEED hElP THANK YOU ALL! Options

[worn]

You may remember me from posts like the squid that ate my transmission. I built an engine and have pretty much solved various problems like leaks and oil pressure and oil temp. It is a 2056 with a 73 web cam + 2.5°.

I had to do some work on the heads. I was shooting for about a little over 8:1 compression, and while I have some uncertainty of deck height I am certain of the head chamber volume all matched to 69 cc ( I would say milliliters). According to CB Performance that would give me a maximum of 8.4 compression.

That is the set up here is the problem. On load I hear a ticking sound, with maybe a tinkling high tone. There are several alternative sources of rattling, but it is coming from the engine bay. The gas here is generally 91 octane. I have enriched the MPS to deliver A/F to around 11:1 at load with part throttle and that has not cured the problem. After break in the car turned more difficultly with the starter so I wonder if the cam may be producing better dynamic compression. The heads overheat if I push air down the road at 70 - they generally don't at 50. Timing is stock.

Question 1. Is this knock/ping/pink(UK)?

Question 2. What are my best options and how quickly must they be instituted. The car is grounded for now.

3 - Thanks!

What distributor?
What fuel source? What carbs? What is the setup on the carbs?

Glad you asked. This has run me from pillar to post in an interesting way. I am learning a lot, but can do that when the snow falls and the salt vampires hit the road.

I am running D-jet. I rechecked my scraps of paper and compression has an upper limit at 9.7 if I completely mressed up and have no deck height (doubt) down to 8.7 if I did the deck height right at 40 thou.
I am running gas from a Stop and Go that advertises recreational gas with no ethanol. Force of habit with old cars. 91 octane, but I now realize that ethanol might be good at boosting octane, snd I might be able to get 93 elsewhere at a name brand.

I added a 6AL cd ignition and I thought about adjustable retard - just right for me - to go with it, but the red box only lasted about a couple of weeks. New out of box but off warrantee due to stashing away.

I finally got the D Jet to play nice. I find the car runs better a bit leaner, but right now the car cruises at 12:1 and is pinking at 11. Charge cooling isn't going to do it for me.

I am guessing I have flame fronts moving unevenly in the squish zone after ignition. I may buy one of those microphones you attach to different places and drive around with head phones.

I came so far. The car runs like a champ. Help! (IMG:style_emoticons/default/blink.gif)
