Sigh.. Weber issues.

[bravekozak]

Everyone with a carb needs to block off their EGR and stop letting that mileage robbing, dirty exhaust back into the combustion chanbers of their engines.

EGR blockoff plate. I can drill & tap the boss for 1/8th NPT on request, if you want an extra vacuum source for whatever.

Nice job, how much are you going to have for it?

Soo.. I learned something today. If you dunno what you're doing, don't try and tune by ear. Finally got a vacuum gauge (mounted in car). Thankfully, no vacuum leaks.

I was able to advance the timing for the first time (all the way and back about 1/3 inch, no ping through 70MPH range, any gear). It REALLY made an improvement.. I had a bit of lag if I floored it, that's gone now. I've been getting 31MPG pretty consistent, which was driving me nuts. I watch the gas gauge, and can pretty much tell when I'm getting good mileage without waiting a tank and filling. Usually shows 5/8 at 82 miles (which in reality is approx 30% empty, and I get 31MPG at that point).

Today I've gone 91 miles and it has yet to hit the 3/4 mark.. I'm hoping for 37+, but wintertime 35+ would make me very happy at this point.

I'm showing 21" vacuum in-gear, coasting to lower speed. Just sitting in neutral I'm at 19. No jumps or shakes in the whole range.

My throttle is starting to stick again.. I haven't had that happen in about a month and a half. I loosened all the mounting bolts back then, and installed a weakish return spring (so I wouldn't damage the linkage). Last week or so it's been really wanting to stick. Drives me insane.

Other than those little things, the Weber is still an improvement over stock by a mile. I'll update with this week's mileage, hoping it gets better!

Thanks again for all the help, everyone.

I had a Weber and had to file out the adapter. The butterfly was just scraping the edge of the adapter. Double check yours. It might just be scraping in cold weather.

I do not have that problem with my twin Mikunis and twin manual choke. It took me three tries to get the throttle cable the right length. But it's perfect now. I adjusted the pedal stop for full travel. Nice.

Hey if you have the chance call me at 870-321-2969 I am gonna install a rebuilt Weber carb and need to know how far to jet it and do I need an ADAPTER ?????

might help here.
myweber did the same thing and I finally just soaked the throttle shaft with pb blaster from the outside of the carb did that to all the carb linkage to and it didn't stick anymore at all so good luck.

[Spike]

I'll try that today. Thanks, Mister Apple.

Are you running regular ethanol gas?
Try super on the next fillup and see if there is any difference with the run on.
Usually super has no ethanol, regular has 10%, and ultra has 5% since it's a 50:50 blend with super. And that's the way the octane cookie crumbles.

I know this is an older post but do we know super has no ethanol in 2016 ?

[bravekozak]

Only Alaska, Missouri and Montana allow ethanol free premium gas.
Thank-you congress for the Renewable Fuels Act of 2007.
Did I mention, you can also get non-ethanol super north of the border?
I use ethanol free in all my lawnmowers and cars.
I have never had any bad gas problems or symptoms.
I read about all of the ethanol problems online.
Pure gas.

I have an 89 L with a 4 spd, 81 escort carb, no computer, no catalytic, rebuilt 93 b3, I have changed from the original jets of 95 primary and 107 secondary, to 90 primary and 95 secondary, this makes the car a turd but once up to speed it does really well, I tuned by ear this takes a while but following webers guidelines its not that hard, I run it just a little rich the car seems to like this. I usually get 45 mpg with driving 55 to 65 mph most of the time. I really like the tunability of the escort carb. Future changes are a 5spd, 13 inch rims/tires, and maybe this dickmeyer detuned cam I have, wish I had that when I rebuilt the motor.

I have a 93 GL with a 5 spd, 81 laser twin Mikuni carbs, no computer, no catalytic, rebuilt 85 B6. I have not changed the original jets as they were speced for a 1.5L Mazda E5 engine. There is instant response from the throttle. I tuned them with a Crypton multi carb balancer. Future changes may be a Chevy 2.8 V6 engine. I was doing some measurements at the junkyard on Friday. One of the eight Fieros has a V6 engine in it. I was checking the dimensions, transmission size and axle lengths. If I can fit the engine backwards, I have the perfect intake manifold for it. My own.
