Fuel injection issues? Possibly run carbs? Options

[ClayPerrine]

You will be much happier than the single pinto/weber carb in both performance and mileage.

That carburetor (or any single) fitted to these engines is a quick way to experience the worst ownership experience possible.
People go to these because they *appear* to be simpler and easier to tune than duals.. This could not be further from the truth. These carbs are damn near impossible to tune, primarily due to the long runners that allow the fuel to form droplets and enter the chambers as liquid that has fallen from suspension and lost atomization characteristics.
This means the engine always performs and tunes like it is rich, even when it is lean.
I rip them off, and crush them with my bulldozer, or tracked armored personnel carrier.

Jake... why do you think I suggested to "float test" the carburetor???? (IMG:style_emoticons/default/biggrin.gif)

Carbs FTW
I do believe an impulse sender is what we call a bar tender up here on Mass.

All joking aside, just fix the FI
It’s most likely something stupid simple.

All the technical advice in the World here from the best in the World but to set the record straight:



The trigger points send two impluses at a time while the Mass bar you can only have one impulse at a time. I know this from experience.

I once ordered a strong beer at a mass bar and the impulse sender was quite judgey and told me they would have to pour it in a little glass and gave me bad looks.

Are the any vendors on The World who Sell this and can walk me through this? I'm ready to order one but I want to ensure I get the correct parts from a reliable dealer.

[emerygt350]

Trigger points are NLA, I think there are some folks around here sitting on some, however I see them for 150 to 200 dollars. That's halfway to a 123ignition distributor, and that is where everything becomes easy. No points, no triggers, installs in minutes, no fuss.

Right on page 1 -- I posted an Ebay offering; $32 for a used set. Took me all of 30 seconds to find them. Trigger contacts are a low current contact switch. Many used sets are still serviceable. There is a guy (Norbert) here on the World that sells an adjustment gauge / tool that can be used to reset trigger points gap even when the rub block is worn.

Another 30 second search on the site using: site: 914world.com trigger points tool

Nothing wrong with a 123 Dizzy but there were MILLIONS of these trigger points made and plenty are still in circulation so let's not pretend that you HAVE to spend $450 + tax + shipping for a 123 dizzy to get the car back on the road.

[emerygt350]

Just too many advantages to the 123. Although you can get these to run and drive on 50 year old triggers and the crappy quality points they make today, for only a little more you can have a new distributor, never buy points or triggers, and have a better running engine. Not to mention all the other fail points in that original distributor. And setting dwell. Makes you feel all old school but it does get old.

Don't disagree.

I just wanted to make sure we don't lose sight that OP may not have extra $$ and that 123 dizzy isn't the only option.

[914e]

My suggestion is to float test the single carb. Throw it in a lake. If it floats, use it on your car.


Now for some real advice... find a complete L-Jet system and put it back on the car. You will be much happier than the single pinto/weber carb in both performance and mileage.

I feel the same about carbs.

[JeffBowlsby]

My comments about the 123 trigger points. Some may consder these nuances, I consider them important, but resolvable. Mind you I have not had a 123 in my hands, am only looking at the published drawings/photos online. Maybe I am missing something? Those that have done this, please clarify and post photos of your solution. If you are driving around with an expensive new dizz and this connection fails you are in trouble.

123 provides 2 wires coming out of a hole in the side of the dizzy body. Ideally the 123 would come with a female D-Jet plug emulating the stock trigger point connection plug where the stock plug on the harness simply plugs into it like it was made for it, and which accommodates the rubber boot as the D-Jet connection system requires. How hard would it be for 123 to fab a rigid plastic connector housing with the terminasl embedded for D-Jet and provide their dizzys with it for cars that require D-Jet compatibility?

In the meantime, these wires need:

-Outer casing to route them and protect them from engine bay heat and fluid contamination. Exposed wires will not last long in our engine bays if not protected.
-A grommet to keep the wire penetration into the dizzy body watertight.
-The male wire terminals in their diagrams which insert into the wire harness female terminals. I have not been able to locate these male terminals and its not clear that they are provided with the 123.
-Some easily removeable and reinstallable method of waterproofing the electrical connection to the FI harness. Electrical tape is not an acceptable solution. D-Jet relies on the rubber boot over the trigger points connection for strain relief, to protect the wires from heat and fluid contamination and to keep the connection physically connected.

D-Jet owners need a total solution for this important connection.

[emerygt350]

Definitely concerns of importance, however, my car is 50 years old, none of the boots on any of my connections have provided the protection you speak of for 25 years. When I run into them I tend to say "oh, that must have been nice" and move on. The 123 plugs into the original connector for the triggers without having to modify anything. After making sure it worked I wrapped it in the good old electrical tape and called it a win. I know that isn't quality work, but it still works incredibly well, so good in fact that I have no qualms about suggesting it to others. Most of the stuff I do I would never suggest others follow. My old dizzy sits on a shelf now, ready to go back in if somebody wants it to, no damage to the wiring or the motor.

I’m sold on 123 distributor… is there a vendor on the world who sells them and will answer questions about installation if I have issues?

[emerygt350]

I got mine from tangerine racing but I am not sure he stocks them any more. There was a group buy on here not long ago so I know one of our suppliers has them.
