I have a nearly stock 1.8 L-Jet with all the smog controls removed. The l-Jet distributer is the dual vacumn type- both hoses attach to the throttle body.

Last two times the vacumn wimped out, I replcaed the can. I'm wondering if there is a better way to go- given I'm not running smog controls.

Are there issues specific to the 1.8 L-Jet ?

Thanks,

jim

Get a Mallory Unilite from Jake all setup with the correct weights for advance.
Close the ports on the throttle body with caps and enjoy the ride.

Jim,
The Mallory Unilite should work...

Until then, run the stock distributor without the vacuum advance (it has too much inherently). Plug the ports on the throttle body. Re-time the car to 28º total advance at 3500 rpms. That's how I timed mine with the L-Jet.

If you run a Hyfire VI/A you need either one of the two tach adapters available. If you need a hand, bring the car by Skline's and I'll help you out with it.

Jake discontinued the Mallory line a couple of weeks ago. I think Chris at CFR/Tangerine has one or two on the shelf.

Drops right in. The ignition cable boot might make light contact with the tin depending on how your drive gear is indexed.

Don't you have to take a BFH to the engine tin around the distributor to fit the Mallory?

Mine dropped right in - no issues. Not sure if that's the case with a '75-'76.

we no longer carry the Mallory.

Too many idiots hooking them up backward frying them and expectinng a refund when it "didn't work out of the box" even when we dyno tuned and test ran EVERY UNIT!!

On top of that getting them was a royal bitch and we had back orders for months at a time.

I have decided to do a Mallory install video and illustrate how to re-curve the unit my way.. I can then sell this video for 20 bucks and not have to listen to people whine about why the unit broke when they didn't pay attention to instructions and fried the damn thing.

I sold hundreds of Mallorys and its a great product, I just can't tolerate the BS they created with lack of availability and technical support.

So Jake;

Are you stocking a replacement dizzy, or are you just providing a referral to the Unilite product (getting out of the dizzy sales completely)?

I think this was the main issue: is the '75 L-jet indexed so the unit will be a drop in. Need to find someone with the same year who has done this; know anyone ?

I've installed them in engines using 1.7/1.8 tin and 2.0 tin without problem. The cable boot will contact the tin as you rotate the dist body. If the gear was indexed such that the boot was against the tin when the engine was timed correctly I would slightly dent the tin.

I think that to install the dist with the cap on you would need the BFH to make it fit. Then you could ignore pages of instructions and diagrams and hook up all of 3 wires wrong. (IMG:style_emoticons/default/rolleyes.gif)

I went to the Summitracing Web site:

http://store.summitracing.com/egnsearch.as...mp;autoview=sku

They show 2 for the 1.8L 914:

MAA4554101 Mechanical
MAA475401 Vacumm

Should I be considering the vac or the mechanical ? Currently, I have the Petronix inside my current distributer.

Thanks, Jim

The 1.8L L jet system is NOT timed at 3500 RPM. You set the timing to 7.5 degrees at 800RPM. And the Vacuum advance is no present at idle, it is a vacuum retard. It provides a burst of initial advance to overcome an off-idle flat spot inherent in the L-Jet design. The vacuum advance hose is not even hooked up on 90% of the L-Jet cars out there, same as the D-Jet.

Update:

Had the Mallory Unilite installed Monday to replace the original dual vac distributer. Very nice ! The car drives a lot better and a lot of the issues caused by the original distributer are gone.

A big thanks to Ed for the heads up, and Chris at Tangerine.

Good news Jim.

Which one did you use? Part Number? Someone may find it useful.
