Carb Sync Tools

[craywm]

Hey,
Quick question. Wanted to get peoples opinions on which carb sync tool is the best. Let me know what you think!

Simple...

Accept no substitutes...

(BTW...before the search police arrive...a quick search would have turned up dozens of threads on this )

Morgan Carbtune and Gunson Colortune. I bought an ebay set of dial sync gauges and the only good thing about them is the aluminum hard case and and the huge assortment of adapters. The needles on the gauges bounce up and down and make it tough to sync.

edit: moments after posting last message, I went to carbtune.com and purchased the carbtune pro. I'm an idiot, since a little over a week ago I ordered the Colortune pro (3 plug set) from them! Should have gotten the carbtune too.

Put the (some) restrictors in the four vacuum lines...

I'll give that a try. The adapters that came with it are steel and taper down to where hose slips on. I though that would create enough restriction, but I guess not. What do you recommend for a restrictor. I'm headed to the big city in a few min so I can look around

In a pinch, take a vacuum connector, mix up some JB weld and place it inside the connector. then when it's hardened, drill a very small hole (.032? or smaller) through the JB weld from end to end.

That doesn't sound like a bad idea. I may try something along those lines, I have some small aluminum piping I can use. I'll make several sets with different diameter holes and see how it works. Thanks!

Hi,

Yes, I love my Carbtune. (See my little write-up.) It uses "dampeners" in the vacuum lines. See their instructions...

This is what the restrictors (dampeners) look like...





Thank you for your indulgence,

Great pics, that gives me an idea. Anyone smoke a pipe? Maybe I could use some of the filters for my Savinelli dry system pipe!

I seen some setups where people use inline valves and close them until the pulses stop. eh. im not sure how effective that would be. just a suggestion.

[goggleboy]

valves would be interesting. What if your restrictor devices are inconsistent with one another? for instance, holes that are drilled aren't exactly the same, or inserted pieces aren't the same size.
wouldn't that throw off your readings
and create problems?
