Title: Stoopid Carb
Post by: moni on April 07, 2004, 04:23:09 PM

the good news is i've figured out why she can't hold an idle... long story short, rebuilt the carb and had it in for a few days, but everytime i come to a stop it sputters and dies. so some sort of vaccuum leak, right? i snugged everything up again, and in the process of tightening the front nut to secure carb to intake manifold, the bolt comes right out.  :angry:

so, perhaps a stupid question, but before i run over to KMS to pick up what i think i need, thought i'd double check: i'm gonna have to tap carb right? is there anything i should be cautious about when tapping a carb? i figure it's pretty much the same as tapping a case, but thought i'd ask around to be sure... :blush:  thanks y'all.

ok possible silly proposal here but couldn't you drill out the hole in the carb so there is no threds then run a nut and bolt combo...kinda a quick fix i guess. or tap the carb and heli coil it back down to the original size.

i've tried jb weld and a few other things. i'm gonna have to go with the small nut/bolt combo. i'm kinda morally opposed to drilling parts.... done it waaay too many times.  B)

As a quick repair i wind a longer stud through the stripped hole 8mm, then have a nut on top. If it is a dual port 34 PICT carb you will have to grind the nut a bit to clear a casting, but if it's a single port it will go right on. If you need a longer stud and ground nut i have some.    VOLKSBUG

I just tried to snugg my carb nuts a little and it pulled right out! So I just used and 8m bolt thru the bottom and hacksawed my 34 pict a bit and a nut! (I am now a legit backyard wit!!) ;)
