To; Peter Stanwick; I read your reply, glad to see you have the improvements you want. I've got another thought, and its totally by accident. I rebuilt the diaphram fuel pump last year, and its been fine,BUT, I decided to switch over to an SU electric pump(MGB style) just so I wouldnt have to hand prime. This change has nearly eliminated any engine "spitting", even at cold temp. Its not running rich, and hot starts are immediate. I'm not going to reinstall the old pump just to do a pressure or capacity test, but I have an inkling that the diaphram pump design is probably marginal at best. Yup, I had to reverse the diode's leads in the pump so it runs on + gnd. Food for thought,,,,,,,,,,,,,,
