Hi all. I am new to this forum but very exited to join.

I have a 1966 SWB 911 with a 1973 911E engine. The engine is in a pretty good shape and according to the previous owner - rebuilt app 12000 km ago (6-7 years).

The MFI has been renovated three months ago and ever since the car has been running rich.

When the engine is warm it starts to "pop" through the exhaust in the low rpm range (idle - 2500).

The air filter, sparkplugs and points are new. The cables from the distributor to the plugs are good. The timing is right.

I have checked the tube from the HE to the cold start thermostat - it is fine, but the thermostat is not warm even if the engine is at running temp.

I have read and followed the CMA to the best of my knowledge.

Any ideas?

Thanks in advance
