I own a 1945 Clark Carloader with a Conteniental L-Head 4 clylinder that was converted to LP. It has a Century regulator on it that does not have "heat fins" on it and is not plumbed with coolant. I recently installed a electronic distributor which made it run great for a short time but the regulator just continued to freeze up quicker and quicker. Now I'm lucky to get a minute or two of run time out of it. Do I just need to replace this regulator with one I can heat with coolant? Thank you!
