Q & A: Idle "Shutters"

Thursday March 27th, 2003
Q & A, MGA, MGB, MGC, MG T-Type, Midget
Hi John,

I emailed you last year about the 1968 MGB "bogging" after idling on a
"warm" day ... I had the car tuned & the carburetors balanced. The car
runs
GREAT most of the time . but, sometimes, when coming to a stop, the car
will sometimes "shutter" and just stall out unable to "hold" the idle.
When
this behavior does not happen, the car idles fine & evenly. In the
"shuttering" mode, I need to pull out the choke to increase the idle. This
behavior tends to happen more when the engine is warm & usually upon a
"restart" of the car.

I also found out that the carbs are of the HIF type .. not original HS4.
Should this "mismatch" cause any problems?

Thanks for your help,

Regards, Rich Fine

Rich!

I apologize for this long delay in answering your letter.

Those HIF's have problems not encountered with the simpler HS's.
You can usually solve the HIF running problems by changing the needle/... read more
