Thanks Doc. I was avoiding changing needle settings until I got the main right, but you're probably right on the clip position. With it idling so rich it's hard to tell what's what, at least for me. I do take the fact that you and other here have experience and the repeatedly consistent final settings that have been posted speak volumes for what works in the real world.

What's still a little confusing to me as a relative novice to carb tuning (I just bought my drag car this past year and although I've read alot on the subject of jetting/tuning I haven't had it on the track yet) is the fact that if you're off by alot with one or more of the carb circuits they can have a large effect if not overwhelm other circuits during the initial stages of tuning/testing. That's what I've found anyway. I tend to look at things as being more complicated than they need to be most of the time anyway.

However, this time I'm taking yours and others advice and short-cutting right to the sized recommended here. Right now I've got the carb off and I'm looking for the comparison chart between DynaJet markings/sizes and stock make to see what is actually 170 in DynaJet. I'll go ahead and change the needle to the third clip from the top of the needle too and take a test drive and analyzer readings. I plan to post the reading when I get it tuned so others might benefit from the comparison between jet/needles adjustments and resulting air/fuel mix. I got my Dyna 3000 today and might try that this afternoon too

I also have a laser temp gun and thought it might be useful to make a spreadsheet when I get back from my trip north listing temps across the engine/oil filter/transfer case/exhaust once I reach my final carb settings too. Maybe I've just got too much time on my hands for my own good?

Thanks again for the advice.

Here's the link to the jet chart comparison for DynoJet and Mikuni once again:

Looks like a DynoJet 180 will fall between your recommended Mikuni sizes of 170 and 165. After checking, that size is not in their kit. Also, the head size of their jets is so small it almost fits inside the stock main's sleeve, so I'm going with a Kuryakan 175 instead and send the DynoJet kit back. I think I read that Barons had a better jet kit?<br><br>Post edited by: sjh55, at: 2006/12/21 14:21
