Jimw,
I would be OK with the light shade of white. Does the engine at highway speeds have any stumble or bumble to it?
Can you tell the secondaries are opening at a certain RPM?
It did develop a minor stumble at low RPM's when I put in the #53's. I assumed it was due to lack of gas; there was no stumble with the #55's. AM I incorrect?
I have monitored the secondaries by doing the following :
by using a paperclip on the secondary rod and then pulling up the same hill just below my home at differnt rpm's in 3rd gear and monitoring the vacuum at the same time.
They aren't opening until vacuum is less than 2" and rpm's are above 2500. The higher the rpm's, it seemed the higher the vacuum reading would be when the secondaries will open.
To all to eliminate any confusion,
I found the plugs a light shade of white from
normal driving. I
have not run WOT for any period prior to finding them like this. This was the 1st time, with #53 jets, that plugs began turning white with 'normal' driving. I have been pulling the plugs to inspect them prior to each jet change to compare.
I intend to do what Hank and Panic advised before I change the PVCR and jets and PV and secondary spring.
It will be a week or two before I get it back on the road due to the front brake conversion.
Deuce,
I'm not sure of the PVCR's other than what has been posted here by those of you with a Holley manual. I have to determine their size prior to drilling, with no guesswork, inorder to deterine my original area for gas flow. That last sentence does sound right, but if you read Panic's post about determining how find the proper PVCR size, then I think you will understand what I mean. A+B=C+D, inorder to find D, then I must know the other three variables, one of which is the original PVCR size.
