It seems that when I make a sharp left turn or change lanes quickly that I lose power, like it's outta gas or something.... don't think it is electrical but I could be wrong..... running an edelbrock 600..... any ideas?

Check trans fluid level, that happens to me when the fluid is low. Really weird but true. Also, make sure the trans filter is still in there correctly. On my TH400, it came loose and may have contributed to the power loss issues I was having.

I would check the float level i n the carb.

I was thinking something with the carb.... don't remember it doing this before I installed the edelbrock...... haven't done much work on carbs other than installing or removing them.......... have adjusted the f/a mixture, that's about it....

Gotta be a carb issue cause mine started doin the same thing after I installed an Edelbrock 1405. Maybe the carb gurus can enlighten us as to why our Edelbrocks dont like goin left!!
I rebuilt mine prior to install and spent a lot of time making sure I had the floats set properly, so that wouldn't be my first thought, but it does seem a likely culprit.

Yeah, would like to know more.... mine is basically straight out of the box......

My truck did that to me. It was my starter bolts backing out. It would let the starter swing over and ground out on the exaust pipe lossing power to the dizzy but would act like it was running out of gas. But only in a left hand turn. So check starter bolts.

Well, ran out an checked my starter, its tight. I still say carb cause it didn't do it when I had the Quad on it.

rogergodding · 11-21-2009, 08:42 PM

yeah, I just installed a new high torque mini and it's tight...... was doing this before new starter as well....

Sounds to me like your float bowl level is too low and the engine is starving out on left turns.

jaymc32 · 11-21-2009, 10:16 PM

Made a landfill run today, so paid particular attention to this issue. Seems to happen only in light throttle conditions. If I idle into a left turn it all but dies, but if I'm into the throttle a third or half it runs fine. So whatever it is seems to only be affecting my idle circuit. Roger, you stated that lane changes affected yours, not so in my case.

rogergodding · 11-21-2009, 11:03 PM

it was a "hard" lane change though, If you drive around DFW, you know what I mean

The only time it has done that "changing lanes" on the way home before I posted this.... it almost died altogether.....
