Motor intake detonations

Sorry for texting in english, i preffer it than using google translator in german.
I have done the Iberian classic raid and after 1000km of competition, when engine is hot (90C but a long time working) when the rpm is low and you press the accelerator, explosions occur in the engine intake. I do not happen with the engine cold. Alwais have done this but when the rpm was very very low. now it has become much more common. When i im in the highway at for example 75km/h and you have to accelerate to go up a hill, the explossions occur.

Any idea of what i have to check first? Anybody have experimented the same probelm? Thanks

Hi, it's more a "slapping" sound than a "boom"? I would say: Check for leak air, check valve clearance, ignition timing, condition of the whole ignition system, carburetor adjustments.

Thanks guys! Will check first the Valve-Clearance. Will be good anyway. If it persists, will check the other things. smiley

Hi -

a few questions which might help to understand / isolate the problem / cause:

1. Are the donations occur rather in the intake manifold than in the exhaust / flam-tube part?

2. Do the detonations occur whilst pressing the throttle (accelerating) or rather whilst releasing after acceleration?

3. Is the vacuum advance for the distributor timing (vacuum supplied by a small tube and screw on the front carburettor) functional and set?

4. Is the damper oil in both carburettors filled up correctly?
