Innovate Motor Sport’s LM1 air fuel ratio meter

You’re going to need an air fuel ratio meter and a good fuel pressure gauge. You’ll also need the knowledge and experience to recognize when to have what air to fuel ratio.

Big Stuff’s air fuel ratio meter

Here’s one of the new billet metering blocks with adjustable emulsion bleeds. These aerate the fuel for more complete combustion which results in better power and economy. There are also selectable jets for idle circuit/transition fuel adjustment. You’ll need a bunch of jets to make the changes for a good tune up. Kits are a good way to go.

Notice the air bleeds for idle and main metering in the main body.

Jet kits are a must.

When it comes to technology carburetors weren’t making much progress until the last few years. There have been a few really talented people that have been improving the old Holley style carburetors, but the cost was prohibitive for the average hot rodder. Now companies like Quick Fuel Technology have brought carburetors to the market that are not only good for making horsepower but are so adjustable that when all of the screws have been turned in the right direction and all the jets and air bleeds have been set the resulting drivability is so close to fuel injection that the difference is hard to tell from the driver’s seat. And there are so many carburetors to choose from that given the correct information about your vehicle the manufacturer can provide you with a carburetor that is almost a plug and play unit. For applications that need to be fine tuned you come to a shop like HRG and we’ll do the work for you, or you can arrange to gather a bunch of people that want to learn how to make the adjustments and HRG will provide a class so that you all will know how to make the adjustments the next time. Call for pricing of carburetor tuning and/or classes.
