I don't like em so far. Doesn't seem to add much power. Why?

 

they don't add much power. just supposed to kick on faster.

 

yeah they wont add any horsepower, all its doing is simplifying the way the secondarys already work.

 

just supposed to give you the power that's already there quicker

 

you mean that mechanical secondaries don't increase the flow of the carb? hahaha

 

not even a little bit.

 

Ok guys I'm thinking you all don't have a clue about how they work "secondaries on carbs". Frist fact they came from the factory inop, the dealers where or was to hook them up, some did and some didn't , some simply charged the custorm to do so, next fact if they are working rite you will be unable to feel it or tell when they are openning up, very smothe ingaugement, next we look at the dieaframe that opens them most larg with a real lite spring inside, becouse when the engine has the RPM to over come the vacuum dope there is not much vacuum at this point to force a small heavy springed dieframe open, and you will find that as time goes on then sec die gets hard a stiff and there for not be working at all, so at this point a pull string hooked up to the sec shaft crank going down the street on the fast side will let you know "give it a pull" per as to be fully open or the inter lock will lock out the sec, and if they where not working befor you'll feel in now,

 

Remember to read the section on the AP as you should enlarge it via gaskets and a longer AP arm. There are some that would say you dont need to. My feeling is the person that did the tutorial knows a hell of alot more than most of us about carbs. So that being said, look at that section and make the mods. I seen an improvement once I got it dialed in. Just bread tying the secondaries shows a flat spot, fixing the AP got rid of it.

My .02 cents

so where do I find this AP section

under I need O' Shot of Gasoline

 

OK I read it , but the part where it talkes about the free floting sen and being able to open at will dont make any sens becouse there is a inter lock that holds them closed and only releases when the per is all most to the fully open stage, any how haven in in my hand make more sens then all that readen

 

Huh?
