Just like the commercials. And, only 1.99 at most stores.

An empty tuna can works for me.
Even better is one with bent-in pouring spout.

Flanker 1970 - The manual has a section that shows the original jets, rods and metering rod springs that came with a particular carb.
It also has a chart for each carb that shows you what to use if - for example - you wanted to lean it down a stage or two.

My 32's 462" Buick engine runs an Edelbrock 750.
It ran great at 350' altitude in Central California with nothing more than a metering rod spring change.

I leaned it down two stages after I moved to Sunny Arizona - 108 predicted today* - and ended up at 3400' altitude.
I followed Edelbrock's manual recommendations and the engine runs great.
Both here at the 3400' foot level as well as down at the river at 450' altitude.

Peruse the manual and decide what you want to do.
Order jets, rods and springs from Summit or Jegs.
Get some jets and rods on either side of where you want to go.

The Strip Kits are nice - and getting expensive - but you'll save some $$ if you buy just the few pieces you need.

The Strip Kits are made for a particular range of carbs and I found the 500 cfm Strip Kit to be lacking for tuning the 750.

Keep your eyes open at the swap meets.
I got a brand new - albeit old and dusty, but only missing a couple of rod and jets - Strip Kit for 750's for $5.


Edelbrock/Carters are jetted rich from the factory.
It's only 5% over from what the expected engine size would be so all that's needed is a little fine tuning.

I understand Holley's are the same 5% over on the rich side.


*108 degrees is a bit of a heat wave for us.
Usual temps now are around 92 - 100.
We're about 10-12 degrees cooler than it is down at the river.
Last time we had a 108 - 110 degree heat wave here, it was 117 - 120 at the river.
