All Walbro carbs need to go. People in Ontario are paying big bucks for the Walbro carb, and that only hurts the class. The existing no-go gauge should be no-go at all not the way its being used now.

I agree with the idea that the gauge should not go at all, and that I know carbs are being manipulated to meet the current tech procedure. However, the precedent for the 602 tech procedure was in place years before the 206 came on line. I would like to see Briggs call out a new "no-go" precedent....and then listen to all the howling over having to buy a new carb and how it ruins the class and the cost of the new carb is bankrupting the racer......
Really, the wording needs to be cleaned up.
I brought this up to Dave previously, but maybe it needs addressed again with Dan.
This is probably the most problemsome area of tech I get questions on across the country.
"Pass into" just doesn't make much sense to me, I guess.
It's simple enough to tech, but gets interpreted differently by some people in the field, and it should not.
Then you've got issues with tolerances on the no-go and variations of how the tool is made that have caused additional headaches in the tech barn.
Yes, there are guys manipulating this area of the carb -- it is NOT just the first couple years worth of Walbro carbs that we're seeing this.
video on correct way to do the .602 check coming soon.Really, the wording needs to be cleaned up.

Yea, teching for a .602" no-go with a gauge that measures .601" will not make (m)any friends.You guys do check the things you check with, right??
Yes. It is also fair to ask the tech person to measure their tool if there is an issue. EX: "could we please measure you no-go gauge just to make sure there are not any wear issues."You guys do check the things you check with, right??
I've run into issues twice with the same tech person and each time they bring out their Starrett vernier (approximator) to try and prove the .602's validity. I should note that in both cases this is the same non Walboro carb being teched and ultimately i have prevailed - but not without the undo angst i have endured feeling like a cheater. Further, the tech tool manufacturer that Briggs has approved/certified produces tools with larger tolerances than the current regulations allow fo. I see the problem lies with the tech tool manufacturing followed by clear methods on validating tech tool accuracy.Yes.

While i agree with verifying, if a 602 is out its useless...same with the majority of the "approved" briggs lo206 gauges. My issue is not so much with tech people, but the poor quality tech tools that Briggs has "approved". The "approved tech tools need to be made to higher tolerances and consistency. I don't think it should be up to the tech barn to have $1000's in NIST certified metrology tools just to make sure the "approved" briggs tech tool they purchased are accurate.It's really up to each tech person to verify the tools they use. Never "assume" a new micrometer or gauge is correct. Trust, but verify and always be prepared to check the rule book and your equipment with the customer. Do everything you can to find a competitor right before you call it wrong.
