New empi hpmx 40's or lightly used Italian Weber 40 idf's?

[Spike0180]

Im correcting the engine combination issue I created.

This engine is in my Bus. And will stay there.

Engjne:
1776 type 1
9.3-1 CR
W110 cam
Stock crank
3 angle lap job stock vw heads
Going to be 1 3/8" exhaust

I have the option to purchase what appears to be a nice pair of "italy" (it doesnt say made in italy or balogna just has "italy" molded on it) or a new hpmx kit from jbugs?

Or should I keep looking for a used set of dellortos 36's or 40 DCNF's?

The used carbs could cost more in the long run. If you do get used ones, make sure you trust the source you're getting them from. Many have bought the "they ran great when I took them off" story, myself included. When we could have bought new.

People are going to knock the hpmx carbs but I'll give you some first hand experience. I've been running them for about 6 months on and off road, after setting the floats and tuning the idle speed screws there great carbs. Only issue I have is the linkage, I have to synch them every month or so, so if you do buy them I would look at getting some cb linkage. The Heim joints on the empi down rods have way to much clearance in them to hold a tune for a long time. You might be able to just get cb down rods but I'm not sure, I'm might actually try that lol.

[Spike0180]

hmmm... Outside the EMPI HPMX's, do other knockoffs tend to be comparable or is EMPI doing better than the others?

Specifically the ones AA Performance sells?

Form what I have read here.
The HPMX carbs are pretty good and an affordable choice.

I recently installed a used pair of 36 Dellorto DRLA's on a 1679.
I could not believe the difference compared to a set of knock off 40 IDF's.
These Dells are the real deal.

Now since I'm upping the fun factor on my latest build (2180 ala Glenn Ring style, kinda). I intend on using a pair of EMPI D-series 45. Hopefully these 45's will work well.
I took the 45's completely apart to clean and set the float levels the day I received them.
EMPI made some improvements to some of the internal components and increased the float bowel size. These carbs were found to be very clean upon inspection. But still went into the ultrasonic cleaner.

Sorry for the ramble.

Just keep in mind that any carb, be it new or used. Needs to be cleaned, inspected and have the floats set before installation.
Doing anything less will spell trouble. Even if the vendor say's "ready to run" in their add. Don't believe it.

Good Luck.

Running a set of HPMX's on my 1904cc. After 5 years and very little driving (less than 10,000 miles) the throttle shaft has worn the carb body and have various vacuum leaks. Would not buy again.

Even without bearings they can have problems. The bearings have to fit tightly in the carbs, and in the MIDDLE between there is no bearing, so if the shaft is tweaked it will wear the middle. On rare occasion even Italian IDFs will develop too much end-play, and wear the sides of the throttle blades.
If you have to -learn- the IDF carbs either way....New/used what's the difference? If I was starting again today I'd get the new ones and try it....but, just doing it for fun isn't real exiting, unless there is some promise they will be in any way superior to what I already have, and there really isn't.
Maybe your first set should be REAL webers, that you learn on, so you know what it's all supposed to look like at least.

The HPMX use a larger venturi and top bore than the commonly sold 40 idfs, so that's neat if you want to try 32mm or larger vents, but on stock heads you want probably 28-30mm so there should be no advantage I can see to get HPMX over Weber

Cheap carbs suffer a lot of press fit parts that...are loose.
What to do??? Loctite!!!!

Apply a thin film of loctite 510 to the bearing OD and housing before you assemble.
Prep with a dremel size brass wire brush.

Well, I purchased some Weber Italian 40's. They appear to be in good condition, and the seller claims they are in good condition though he doesn't know the history and hasn't run them on anything. So... not super convincing I guess. Anyway, here are some pictures from the seller:

I'll post how they work out later this summer.

I have reserves about the linkage, but for now it'll have to do.

Thoughts? opinions?

HPMX

[YDBD]

Linkage looks like CB performance except for the carb plate which is aluminum. Check the classifieds or ebay. Check the heim joints for play, other than that it's about the best out there.

Your cross bar looks the same, but the carbs should have the aluminum plate. The EMPI HPMX's I have now have a stamped steel instead, not as good and the heim joints sucks.

This was the old CB performance Hexbar from the 90's which is about the same as they sell now.

Spike, There are no cb parts in your linkage. Thats Redline style linkage. Its ok but beware when clamping down the linkage arms, as they can crack easy. Cast aluminum doesnt like to flex.

I think CB was the first hex bar then a lot of copies after that. It might be in your best interest to find new...
