You should not experience flooding at any setting, if the float and needle/seat are doing there job?
Raising the float simply raises the fuel level, it wouldn't flood unless the float was hitting the gasket or being held down by something as it tries to raise up to seal off the needle....Cliff
canadian nascar:
Hi Cliff,
I will try the 1/4'' float level again.
In the previous post I wrote that i have haveing a terrible time trying to get rid of the lean bog, last year it was so easy. I put JB weld in the holes and am going to redrill the holes according to your book.
took it apart again yesterday and the tubes were a little loose so i pulled them and checked for debris, didn't see any thing, put all back together and tried again. still lean bog tighened up the spring some again, anywhere from 1/2 to 1 1/2 tight and still lean bog with .07 POE hole.
Any ideas on how to get rid of it
stock turbo I was able to get rid of it.

Cliff Ruggles:
Have you tried shortening the primary accl pump shaft slightly? It may need a bit more fuel from the accl pump.....Cliff
canadian nascar:
Hi Cliff,
It's been a while, I have no lean bog now in seat dyno, but the wide band shows one, when I go wot, I took a bit more than a 1/16'' off the accl pump.
I have a bit of smoke when I start the car, rich at idle but wideband shows 17-1 afr, idles starts good. Should I go leaner?
The 5 second 60ft was all fixed with going to a higher stall converter, was told by Buick 3.8turbo guys that I should have a 2800 stall but ends up a 2600 10'' converter. I can really lay a strip now, and if I cruise at 30mph and go wot it will start fishtailing.
Lastly the wot is 10-1afr for a moment then goes to 11.5-1afr. Some more fine tuning is needed but storage will be in a couple weeks.
