Ok I had to take the carb off and I did some basic checks all the screws that hold it together where loose. but the rest checked out ok ( for now) I will be rebuilding it down the line.

 

removed the steel plugs that house the idle mix screws. and cut some grooves into the heads as they  have no provision for screwdrivers.

 

Since then I have been reading up on tuning q-jets and the like using a vac gauge. not as accurate as a wideband but i thought i'd give it a go.

 

gotta say spenno I dont know why people  poo-poo the quaddie cos it was quite easy now my 308 is idling like a boss and has a nice crispy revving sound 

(if you get what I mean)

the only thing left to do is to recurve the dizzy.

 

mind you a wide band is still a must in IMO along with the book 

 

your thoughts/abuse please!

I can do but there are shit tonnes of pages (that ive been reading depends what your after) 

 

Thirdgen.org are good for later quads

 

73-87.com -chevy truck site has a few good tips for modding

 

hotrod.com (I think thats them -gave me the basic rundown on vac tuning)
