I was looking at the ABM model, it looked better built?

Possibly, about the same price.

I always liked the analog guage type better, I've always had better results.

Mine are adjustable too so I can hook them all together to a common vacuum source and calibrate them to read all the same.

So it seems most on here like the carbtune sync tool. Can I get this in the states? I should ask how long it takes. What about the ABN carb vacuum sync tool? Thoughts on this are appreciated. Went to change the oil and filter and found the washer was missing by the spring and filter. The rubber bushing it would have sat against was inside the filter itself when I took it apart. Oh well ordered that washer.

Morgan Carb Tune comes from across the pond. Took about 5days for me to get one some 4yrs. back. Compared it with my mercury filled manometer and it is spot-on.

Hi All

Bax:

It's beautiful!

Aren't you going to miss all the fix-it-up adventures?

[timktm]

Nice Bax, now get off my thread, just kidding. That bike is clean.

WELCOME, Bax!

Very, very nice bike ...

I personally use the vacuum gauges with highest vacuum reading method for idle mixture setting. The Morgan Carbtune is not sensitive enough for that method, pretty sure.

No, it wouldn't be quite sensitive enough. Besides, 'highest inch vacuum' IS incorrect method. It leaves mixtures a bit on the rich side, and creates lower mpg.

Motoman, It works just fine for me and also for many others.

Hi Bax,
Welcome. Nice looking bike. Does it run as well as it looks? Has it been restored or was it kept in such good shape? I think those slotted roors are from 81 so you may want to check your VIN against the list ( which is hiding somewhere on this forum)

What is the best method. Looking to get it set as close as I can the first time. I bought the gauge set to do the sync.

No the manual says 79 sg. I did change my signature just couldn't edit my post.
Tim

SG makes it an 80model..............and the slotted rotors ARE correct for an 80SG(80 Special) and 81SH(81 Special, and they would be correct for an 81Standard(Venturer) and XJ1100.

If your hearing is pretty fair, back screw out a turn or so, then gradually in till you hear a sound change. Them back it out 1/8, to a 1/4 turn at most. Go to next one repeating procedure. That IS the lean-drop method for carbureted scoots. Carburated autos is same method cept after sound change screw is to be backed out 1 1/2 to 2 turns whether it be a four or eight banger motor.......so there ya' go with both fields covered.

[timktm]

I'm at 2 turns out now. Should I start there or start one turn out?

IMO, anolog is always better........whether it be electrical or vacuum related.
