desmog require recurve? (1 Viewer)

[skipdup]

I can't find the answer, though I know it's probably been covered...

If I desmog, why recurve the disty?

Thanks,

the desmog changes the vacuum and mechanical timing on the dizzy. The recurve adjusts it back to usable degrees

Thanks Doug!
Is it required or better?

 

[Pighead]

Not required, just better.

An old timer at an engine shop suggest I do this as well. He recommended a local shop which was nice. Haven't done it yet 'cause I'm waiting on a new carb.

A de-smogged engine doesn't like to be advanced as quickly as a stock one. You may get a little pinging on hard acceleration without the re-curve. Running a higher grade of gas or retartding your base timing a little will help until you can get the dizzy recurved.

Thanks guys!!

recurve?

What the heck does that mean?

an 84 fj60 with a 32/36 weber-I'm planning on removing all of the smog equip and running the airpump uncorked and spinnning free.

do i still need the recurve?

If I take it to my mechanic, what should the timing the be?

The thing runs ok now, I have the vacum of the disty hooked to carb, should I use the one closest to disty or farthest?

my desmog did not require recurve....I did not get high pinging just a higher RPM when driving....so swapped the vacuum advance to the outer port and all is good.

better but not required....and depending on your dizzy I think.

JimC recurved mine - worked great.

Jim C doing mine also. If you want to run the HAC you really should. There is way to much advance in the smogger timing.

What does HAC stand for?

HAC is High Altitude Compensation. A recurve is not a requirement, but it sure does help. The second spring on the Cruiser's distributor is so stiff it simply won't allow it to advance beyond a certain point.
