Go B 4 The show...

I have a 1975 Delta 88 Royale convertible that will run for about 15-20 min. then when I try to drive it at high speed or even rev it up it starts to sputter and choke out like it wants to stall out. Recently put an ignition coil in it, but problem still exists...smh. Anybody have any suggestions? Only thing I could think is carburetor issues...Before I do that I was thinking the module in the distributor. Any advice is greatly appreciated,

Thanks

when ever this happens to me I remove the gas filter and put on a new one.
I dissect the old one and if it is full of grit I assume the carb needle valve is sticking
too and I remove the carb, take the top off and dumb out the sand. Then I re-assemble
it with a new gasket kit. That usually fixes the issue. The spark on these does not usually collapse if the car is able to start. The other thing is if you have a jumped timing chain but that usually also makes it hard to start. It sounds like fuel starvation to me.

Well if nothing else dumbing out the sand would help.

I definitely agree that the spark had not collapsed if the engine is able to start.

I also second the fact that a jumped timing chain makes an engine start hard.




But seriously macstone;
A bad ignition module would prevent the engine from starting; if it starts at all the module is good.

Is the engine in good tune, ie; good plugs, plug wires, etc?

Is the timing properly set?

Do you have a service manual? If not I suggest you get one, and follow a fuel pressure and flow test.

Good luck!
