Re: Hypermiling with a carburetor

If you're worried about that, do your metering rods ride on springs? If it's like my Carterbrock, you may be able to adjust it out with lighter springs. If other springs are available, I imagine they are listed by their equivalent vacuum values.

Re: Hypermiling with a carburetor

The power piston has a spring. I don't remember if the metering rods do or not. Data on the power piston spring is somewhat rare and maybe not accurate but I have found it before. Thanks for reminding me that I ought to buy a set of springs.

Re: Hypermiling with a carburetor

You're kidding yourself if you think wide open throttle saves money.
Better fuel economy maybe but it doesn't save money, it wastes it.

Full throttle acceleration puts a ton of additional wear and tear on all of the components involved that far outweigh any fuel savings, just the tire wear alone, a set of tires for my car runs $400 and that's just for starters.

Ever price a transmission?
They're like 6 thousand bucks.
When's the last time you changed the fluid and filter in yours?

Light foot on the throttle, even more so for carbureted.

$6000 for a transmission? I'll sell you 10 or 12 brand new ones, I'll even sell you them for half that price installed. You don't know a lot about cars do you?

Re: Hypermiling with a carburetor

Why would tire wear be affected by full throttle acceleration? We're not talking about accelerating any harder than a normal person does, just about throttle level. Anyway I pay $25 for tires and I wear them by going fast around turns.

Either way, the carburetor does not gain efficiency with heavy throttle.

My transmission came in a $250 donor vehicle along with a battery, clutch master and slave cylinders, two sets of wheels including a few decent tires, various other parts I used quite well, and of course plenty of scrap metal. There is no filter in my transmission and the fluid is 20,000 miles old (except the quart I just put in because it apparently leaks - looks like I've got some gasket work to do this summer).

Re: Hypermiling with a carburetor

$6,000? I don't think a brand new (not remanufactured) CVT for my Escape Hybrid would cost that much. What on Earth do you drive?
