Stumbling - Disconnect tach (1 Viewer)

[Webster]

I read in an old post that quite a few members cured a stumbling/hesitation issue by simply disconnecting the tach at the coil.
I have a question for those who know about this fix.
The tach disconnect only works with those running stock ( Asian) carb, correct?
It is somehow effecting fuel cutoff solenoid on carb?

I have a Weber so don’t expect the tach fix will help me?
Or is the tach messing with ignition system?

I should mention I’m desmogged.
Thanks!

have you tried disconnecting it to see if it helps?
The tach signal also goes to the a/c amplifier and emission control computer . A recent post here had a issue with the engine cutting out over 1800 rpm only with the tach connected. I think the emission computer relies on the tach signal to activate something when decelerating. Your desmogged weber setup should run the same with or without the tach connected. In theory

Would help if you could post a link to the post where you read that.
