Hello out there......my car just got back on the road due to a bad coil and it was tricky to find as it still sparked the plugs....just not under compression. During wrenching we altered the timing and it is at 33 degrees btdc now. Car starts great and has tons of low end.....kind of stops pulling at 5,000 rpm with slight knocking. Replaced seemingly healthy vacuum lines to distributor and high end improved a bit and some knocking sound lessened. What are your experiences with not being at 27 degrees and what are the risks? Thank you very much. BTW.....not driving car for months is depressing and now driving is really a blast!! No wonder we are here.

Does anyone run 'locked out' timing on their type 4? I have seen it done on many other car engine configurations. Many magnetos are 'locked out'. But I have not yet seen any threads or talk about it here on world.

But I have not yet seen any threads or talk about it here on world. when you say "locked out" do you mean to lock the advance plates? We used to run a locked advance distributor on a type 4 race car Literally had a sheet metal screw locking it but you need advance and retard on a street car. on a full race car that only runs in a power band between 5,000-7,000 rpm you don't need anything but full advance. it would bog and run crappy at low rpm. starting isn't fun either |
