Anyone ever try the "Synchrometer"?

[Brosky]

Rob,

I knew the procedure for the twins, but never thought about doing it with the two outer for the trips. Mine are set pretty well now, but I do plan to install the cable kit from Ratco, when UPS finally finds the lost package that I was supposed to have Weds and I want to loosen the solid couplers at that time and double check everything before the final cable setup and lock down.

I guess that it would be over kill, but I planned to make a plastic fixture to slip all three into at once that would hold them in place on the carbs and allow setting to be done rather quickly and with no lost motion. Just my thoughts.

Any new tool sounds good to me! As the saying goes "A job worth doing is one that requires the purchase (invention) of a new tool".

Yep, the setup for the tripples is the same as the twins +50%. I only use the middle as my "control" as there is some "spring" in the throttle shaft connectors, but with your solid setup this may not be an issue.

BTW are you sure the solid links are not what's causing the fast idle? The butterflies aren't binding when the carbs warm up are they? Another possible cause of fast idle can be the temp compensators (under the white plastic covers on the RH sides of the carb bodies). I have no idea how these work, or what they are really supposed to do, but folks claim they can cause idle to speed up at temp. I'm sure your carb man set these correctly, and I think you wouldn't want to touch these other than as a last resort, but something to keep in mind. I notice my idle wanders a bit and it seems to be ambient tempature related. But I always carry a screw driver in the boot and if it gets too far out of wack, half a turn on the idle screw will set it right. The tripples sure look nice too don't they? What are you doing for crank case ventillation? ERG? Catch can? Other? Mine just feeds into the back plate on the centre carb air filter, but am wondering if there isn't a better solution.

Rob,

I don't feel that there is a problem with the linkage as far as the solid couplers are concerned. I can release them and the idle remains the same, so the shafts are not binding. I'm not touching the carbs, other than the idle screws, since Jeff at PalTech seems to have them set perfectly, judging by the way that he car runs.

I think that the problem is in the mechanical linkage, which is why I've ordered a Ratco cable kit. Now if UPS could stop losing the kit and finally deliver it to me, I could see for sure if the old design linkage is binding.

As far as the ventilation goes, here is the latest picture showing how I have it routed from the valve cover thorough the four way tee to the carbs and cannister.

Paul:

Your setup is looking very nice indeed. Nothing like nice new rubber hoses and fittings under the hood. Looking at the photo, its not clear were the canister and ERG are - I think these usually go between the valve cover and the vacuume "T"? Could be what you have - just can't tell from the pic. Enjoy the new horses under the hood.

RT,

Emission vapor canister is at bottom right side of photo, above anti-run on valve.

What is this thing that you refer to as an EGR valve?

 

[RobT]

Don't claim to know the details of the mysterious device referred to as an "ERG valve" but believe it is supposed to stop blow back of fuel and flames into the crank-case if you get a back-fire through the carbs. Basically its just a one-way valve. Perhaps ERG = Explosive Reflux Grumpiness, or something like that. Sorry, that's the best I can come up with for now. Not at my best with TLRs (Three Letter Acronyms) this time of night. Seems like most folks put one in when they connect the crank-case to a vacuum intake on the carbs. I don't have one on my setup since I'm venting direct to the air filter box. Installed one when I mucked about with rerouting the crank vent to the vacuum but changed it back again. I just couldn't quite get comfortable with my vacuum depending on the leaky old engine, the same vacuum, mind, that powers the brake booster. But that's just me.

RT,

Oh, I see what you're getting at. I think that they used call those "flame arrestors" in the old days.

No, I really don't need one, since this is the same as the factory setup for emissions to the intake and cannister, except for one extra carb.

That other type E valve is long gone as you can see.

Whoa......Bonus day today!!!! /bcforum/images/%%GRAEMLIN_URL%%/hammer.gif

New Synchrometer arrived today and the "missing Ratco Throttle Cable kit" was rescued from UPS prison and delivered as well.

Eight days from NY to RI. You'd think that I was in Puerto Rico or some other weird out of the way place.

 

[RobT]

"Factory setup for emissions" - ahh, now I'm with you. I thought you were plumbing in one of Mr. Good's oil catch cans. My mistake. I'm afraid the original emissions setup on my car is long gone so I'll be no use to you there.

Rob.

 

[Brosky]

Rob,

That will be a last resort. This weekends menu will feature the throttle cable kit, then the SS packing inside the baffle in the valve cover.

Oh, yeah, gotta check torque on head as well, while I'm in there.

The 6 cylinder engines had an emissions/EGR valve only on the engines which had an inlet port tapped into the intake manifold for EGR vacuum.

There was a run in the early 70s of engines which omitted the port on the inlet manifold, & instead had plastic ports directly on the sides of the carbs. Those did *not* use the emissions/EGR valve. It looks like he's using the carbs with the integrated plastic ports for his triple carb setup, to simplify issues with the triple carb manifold.

If he's using those carbs with the side plastic ports, then it's equivalent to the factory scheme with those carbs of no emissions/EGR valve: just tee'd to the carbs & carbon canister.

 

[Brosky]

The carbs/hoses are the same as my 1974 stock setup and vent to the canister exactly the same way, just one more carb added inline. I removed the EGR in the head years ago and replaced it with a brass plug. You can see it just to the right of the heater valve and under the choke cable.

geez...You guys with these 'high tech' carb syncronizers are killin' me...

I thought I went high tech when I started using a green-stripe rubber hose for the job...hehehe
