Don't know your situation
FUEL PUMP--sorta an expendable Item!
Carburetor--1975 lots of wear--Rebuilding is a tough thing to do correctly, proper tools, vatting parts, internal adjusting that must be perfect....still using worn parts
A rebuilt one has been picked over at the reman place, only good parts are used...you usually get a 1 year warranty......Slap it on and with the proper meters and gauges adjust the, already close, mix screws...set the idle speed and maybe adjust the choke.
Don't turn in you core till everything is good to go!....You may need brackets or the number should the "New One" not work out!
Unless the muffler system is "Clogged" or restricted, probably not part of the equation
Elaborate on the "Mechanics" abilities, history, references, "Real Tools" (That one, has pride and takes care of).....I feel sure he is not a "Business".....That's OK, to try to use inexpensive resources.....I do too!
THEY MUST BE KNOWLEDGEABLE AND CAPABLE......Not just, "I an fix it, I can fix it"......Kid down the street with a go cart!
Sorta get a glimpse of me in this link
Let me know what you need, or need to know, I'm here to help....I try to case by case, do the best I can for you!
Let's try the BRAND NEW FUEL PUMP 1st.........May get lucky with the Carb!
