Weberiffic! My latest install.

Post by splatterdog » Fri May 18, 2007 10:35 am

Finished up last night on the 86. I love it when things start right up AND run good. Went a little different way on this one. I went with a holley regulator on the fender. My 84 has one of those dial regulators zip tied to the brake booster hose like I have seen others do. I blew the first one in 90 days. Luckily the 3/4 tank that got dumped out never ignited. Second one is still going but I think I will move it. The holley has a vent hole so that if it ruptures it will spray behind the gauge and run down the fender. Also less heat may prevent failure to begin with. Also you may notice my egr to pcv conversion. More hood clearance without that crumbly heater plate that impedes flow also. They look like a perfect piece for a vacuum leak too. The first pic also shows the marks to port match the adapter.

The car runs amazing now. I think the 84 is getting the same jetting which by the way is Mains-pri130,sec150 Air jet-pri170,sec180 Idle-50 on both. These were for 1000 ft elevation FYI. The jet kit instructions also has the secondary high speed tube get blocked off. Have to wait and see on mileage but I think it will be excellent. Cruises 65 mph with almost no pedal. WOT is just a little better than the out of the box jetted on my 84 but everything below that is way better.

Sweet!
Clever PCV to EGR mount!
Can you ditch the vapor canister for more room/sanitary appearance?

That would be the connection for the Prestone cooling system flush kit that was installed by the owner before me. I never had a use for it, so it hasn't been undone for several years.

Splatterdog, I wouldn't recommend opening it unless you have some replacement for it. There's a chance that it wouldn't seal back up upon trying to close it.

I looked at it as it ain't leaking, don't mess with it. ;)

Well I did mess with it when I flushed it and yes it does leak now. Only a drop once in a while. So slow i wouldn't have known if I hadn't actually seen a droplet fall while doing this job.

The bit of tree hugger in me has me thinking on hooking up the evap system. Low on the list though. Timing belt kit and cam/crank seals and a pre-emptive water pump are next on the list.

I was on the interstate today and cruised 70-73 mph and still needed just minimum gas pedal to do it. The bottom end on this new carb is excellent.

Mileage figures are going to wait until I get over my happy foot. :wink:

I really want one now.... Again.... Damn you money...

So you can reverse where the fuel feed is?

Cool.

I dunno how effective our EVAP's are anyway. Though, I am not a fan of the brown clouds either. Thus me wanting a new kitty rather than keeping it hollowed out.

I'm curious the emissions difference these make. Not like it matters for me. They abolished emissions here. Cat is still a federal requirement though....

No smoke anymore

Post by splatterdog » Tue May 22, 2007 9:25 pm

I don't know if it's the carb or the pcv mod, but just like the 84, start up is smoke free now. Both had smoke that would indicate weak valve guides/seals(blue) before each received it's weber.

That really is a clean install. How did it end up affecting your gas mileage?

If you simply ditched the charcoal canister and vented the tank into the atmosphere, you would most likeley have a stinky gas smell around your car. Besides, charcoal canisters don't affect how the tercel will run or its performance.

I'm curious about the fuel regulator. I was going to do one, but I put the gauge on without the regulator and only got 2.5 to 3 psi. Did you ever check yours without the regulator?

I'm glad you asked. I can bottom the screw on the reg and still only get 3psi max. After everything gets warm it drops to 2.5. The only pressure spec I could find easily was from napaonline.com. They list 3.5-4.5 psi for their new pump.

My pump looks like it could still be O.E. so it may be getting weak but's still kickin and no breather hole spew. Never measured the 84. Got one of those chrome dial reg's in front of a napa pump and blindly trust it.

Also, previously I stated startup smoke was eliminated. Mostly true. It was almost totally eliminated on the 84 and greatly reduced on this one(was a yard fogger). Valve seals are on the list for both though.

Still want to get a couple of 7mm heat spacers too as both do have some hot soak/starting issues. Most likely due to the stock heater/spacer plate elimination.

I guess more than anything else the reg has provided peace of mind and the admiration of some people that don't have a fuel pressure gauge/chrome reg under their hood! haha. Even one "holy s***" from an autozone kid. He's obviously easy to impress.

Feel my wrath!(as soon as the snow flies....)

I just joined up today! I just got a 1984 Tercel 4WD for free! I was told it needed a an igniter because it showed no spark.. Turns out the timing belt was snapped clean! Doesn't make for a very good spark when you're not turning the cam :oops:
So I'd like to put one of my 4 32/26 Webers on it. I have tons of jet's, and lot's of experience with the 32/36.
I was looking at your jetting kit specs for the Tercel @1000 feet, and couldn't understand what "they" meant when they said to block off the secondary tube??
It sounds like either blocking off the power circuit in the carb, or the secondary air jet. But you give specs for that air jet (180, I believe). So I'm dying to know just what circuit actually gets blocked?
Thank You Eric.

The jet kit from racetep.com had the secondary enrichment orifice(top hole in secondary bore) get blocked off. An old trick they said. They suggested jb welding the hole in the air horn at the gasket side of the passage. I ended up tapping a small set screw into the carb body instead to make it easier to remove.

The fatter secondary main jet is supposed to make up for it. It seems a little better than my "out of box" weber. The larger primary idle jet made the biggest improvement.

Alrighty then.. This is the enrichment hole that begins fuel pick-up from another hole in the float bowl, then leads up to a 90 degree brass fitting in the air horn? Rather than the vacume supply to the "power jet" plunger in the carb, I'm assuming.
One thing I think seperates Weber racing carbs from their "street-able" carbs are these little enricment circuits you find on the non-race carbs. One of my 32/36's used an idle cut off solenoid, while some of the other 32/36's didn't. Weird. I even saw a 32/36 used as a standard factory carb in Europe once. Although I can't remember where or which or when. Even the HP Books Weber Carb Book seperates the Weber line into racing and street versions. And they claim the 32/36 being intended for engines from 1147c.c.'s to 2000c.c's.
Good running carb.
I've never liked the enrichment circuits built into them. So, thank you for the info! That will have an impact on the final jetting specs for sure. But than again, so will being at 7200feet in New Mexico.
Thanks again.. eric.
