Further adjustment

Now my VW 1302 Super Beetle has passed The Legal Inspection for License and obtained the capability to go on the high way road.
But I feel some inconvenience on the AD motor operations mainly on the 34PICT3 carburetor and retarding diaphragm equipped vacuum advance system on the specially designed distributor based on the concept for the anti-pollution.
Problem is caused on the first idle stage as the motor stopping tendency in relations with too short activated interval on choke system or too lean idle mixture.
Acceleration hesitations is seen sometimes as is notified in the web sites.
I'm considering about the operation of original distributor by cutting the diaphragm module in two pieces and repair the defected diaphragm with some adequate thin rubber material?
Or buy newly the distributor with a single vacuum diaphragm(no retarding but advancing only).

Insulating noises from the ground and engine room, good rubber material I'm keeping was remembered, wrecks of working place floor rubber with beige color, enough thickness and weight has it.
The combination use of this material with needle Fuerte effects of insulation would be obtained.
