Holley/Demon Carb stumble
Ok, I figured it HAD to. :)
You know, I just had a stupid simple test to try... Disconnect the secondaries. If you still have a transition issue, well, you have a transition issue. lol
If it blasts out and gets up on the tire, the carb is too big.
Now, when you get your new job NEXT WEEK :) you may be closer to sea level and this won't be such a problem. :)
