It has an integral ignition coil and can produce a far stronger spark than the stock points system with a divorced coil, so that a wider gap can be used on the spark plugs. Maintenance is easier also, with no points to adjust or condenser to replace.
First though, I would learn the complete systems of my new car, including how the points distributor works and how to service and tune it.
Remember this.....a carburetor does not need high pressure to operate, so be careful if you have to replace the fuel pump. If the needle and seat "see" more than about 5-6 psi of fuel pressure, they will unseat and allow the pump to blow raw fuel into the intake manifold, creating a tuning nightmare that you may never find. A Carter "Muscle Car" pump will be the best replacement if your pump fails. Carburetors are not like fuel injection, more fuel pressure will not make more hp.
How do you adjust the fuel pump pressure level? Are there instructional videos or anything like that you know of? I found out from the previous owner that the cars "bogging" problem was way worse before he had the carb rebuilt a year ago. He said after he had it rebuilt the boggi g was a lot less dramatic but its still a serious issue
So im really curious as to what the problem is here. Is it a bad fuel pump? Maybe the fuel line is clogged somewhere?
