Wanted Distributor B20B Engine

lelshaddai · Sep 17th, 2018, 16:13

My PV544 has a B20B engine in it. This is the distributor in it and have been advised that it is not correct. With this type of dizzy(retard) I cannot use vacuum advance(is is disconnected and plugged) What is the correct dizzy that should be in it? Second does anyone have one for sale?

lel;

You don't need vac advance and certainly not vac retard...leave the Centrifugal Advance in that Dist anyway, and you'll be fine...just plug that hole in Dist, where Vacuum pot used to sit...there's no need to over-engineer this!

Cheers

Right now the vacuum pot is still attached and I plugged the connection hole. Is that OK or do I need to remove the whole pot and cover the bigger hole. It really runs rough until it warms up and even then it shakes a little at idle. I have tried numerous timing changes and they do not seem to help. I have rebuilt the carb and tried different jets and that does not seem to help. She seems to run rich and idles(diesels, run on) when shut off. Weber 32/36 carb.

Don't remove the vacuum pot Lelshaddai. The plate with the contact on will move otherwise.
Does the centrifugal system work and come back?

I will check the number of this dizzy later, regards, Kay

OK, timed to 10, idle is 650. Major dieseling (run on) after shut off. After it warms up. Hot here today. Run on is Worse than before. Actually keeps running. Running 160/165 in the jets. Can timing cause run on? The car is off. I have seen too lean or rich can cause run on. Which is it? Which way do you turn the mixture screw to make it more lean on the Weber 32/36? Are the jets correct size?

Certainly looks as if it needs a good clean out. It all comes apart easily and then you can inspect the weights and springs. Get some oil on the felt pad below the rotor, that looks dry and that oil lubes the shaft bearing.

B20B - 0 231 146 099 (B20B Amazon in parts book)
However, your engine might be from a 140 and that will likely mean a different Bosch number. Do you know what car your engine came out of? I think you may have mentioned this.

It was from a 1969 144s. B20B
