Unintended consequences

[cutlass389]

I've been striving to improve the suspension travel in my Cutlass. I've increased the front up travel by 2.5" and the rear down travel by 1" along with new Hoosier 275-60x15 drag radials. Although my 60's haven't really changed, I believe that they will be more consistant and better able to handle a greasy or marginally prepped track. I'm getting daylight under the left front now and therein comes the new problem. I've got a new stumble on the launch that wasn't there before. I think the rear jets are being uncovered for a split second so now I've got to get some extensions for them. Discovered this today at test n tune. I made seven runs and the 60's were(in order) 1.612, 1.604, 1.606, 1.600, 1.601, 1.614, and 1.605.

Did you try raising the rear float level a bit? A little more fuel in the bowl during launch might help.

Good thought. No I didn't try that. It's set at 1/2 way through the sight glass so I thought that was pretty high already. 1st race is next week so I'll put extensions on just in case and I can raise the level if necessary. Thanks.
