74 Maverick Odd problem

[95MustangGTC]

I got a frantic call from a friend of mine last night.

Her 74 Maverick is acting up. Its a I6 with a C6

She described the following:

When shifting into reverse it goes into gear but when she adds some throttle it dies. It also does it when at a stop in drive and adds some throttle. The car can acclerate at idle without dying.

Any ideas?

The fuel pump, filter, plugs, wires and cap are new.

I have a 74 Maverik and just happened to notice this thread.

I'm not a mechanic by any means, but I can share my experience with my Maverik because it just started doing this again this past week.

When it's cold outside...the Maverik will not go into reverse until it's running hot. Not just warm, hot. I've learned to just back into parking spots so I don't have to wait for it to warm up. Otherwise it will start, warm up, go into reverse...but the second you press the gas it dies.

I had to bag the timing off a bit this week as it got colder because it was flooding itself. Stopped it from doing it when put into drive.

I don't know if this helps at all or if this is the same problem you are experiencing. I'm hoping to hear a mechanical explanation from someone here as well.

Will it still do the same thing if you ease into the throttle?

Kinda sounds like a bad accelerator pump in the carb... except
that it works okay in drive...

Spray some carb cleaner around the intake manifold,base of carb.check hoses for vacuum leaks. Pinch off the hose to the vacuum booster and see if that helps. Sometimes you have to pull the carb and clean it as dirt in the jets and it won't work correctly.
