MG MGA - A little burbling
|What would cause a little burbling out the exhaust pipe when coasting down hill? It dosen't do a full blown backfire, just gets a little more than throaty. |
Is this normal with the standard exhaust set up? Is my timing a little off or too rich on the mixture?
|When coasting, you are letting the drivetrain power the engine. This is also known as engine braking. It will cause the sound you hear. Note that it will also help loosen carbon in the engine.|
|Probably a tad too rich IMHO. I suspect this is a contributor to blowing out the fibreglass material in my SS exhaust.|
|that could be too.|
|Thanks Mark and Dominic,|
It would be pretty easy to screw the jets in one flat or two.
|Pardon my ignorance, what is "burbling"?|
|I've heard even Canadian brooks burble, Andy. Perhaps better, the sound of milk exiting a glass bottle comes closer to the liquid sound of an exhaust burble; "blub, blub...." Harley Davidson has even trademarked its distinctive exhaust burble at idle. |
|Or perhaps a V8 powered A - I truly hope so!|
|As they say about Harley Davidsons they don't have a throttle, they have a volume control!|
|Thanks for the explanation Ken. I know that sound. By the way, I've heard of babbling brooks but I've never heard of burbling brooks.|
|Can't remember what book it was in, but somewhere I read that the Germans used to refer to the MG exhaust note as "Das Burble".|

|That exhaust sound when running off-throttle is one of the coolest sounds an MG makes. Don't "fix" it, celebrate it!|
