Simple. This type of pump does not alter timing, only delivery volume based on the rack position by governor input. I will be performing this operation on an old Simms pump very soon post rebuild.
@@alexanderrosales7675 have you ever had a Roosa master pump apart? Parts for a rebuild are usually about $26. And they'll go about 40 years before the seals and flex ring deteriorate and need replaced. The p and a Bosch pump are excellent for delivering huge amounts of fuel, and they are very durable. They are complex and expensive. Bosch distributor pumps are null-acht fünfzehn.
