As mentioned fuel filter or maybe pump failing?

We'll find out about the filter tomorrow Sieg. I don't think it is cause there was a lot of fuel dumping out of the filter end when I disconnected it but I'll pull it off and take a gander at it.
Pump could be it also but I already have an extra MSD box laying around so I'll try that before I need to spend on a fuel pump.

You should just put a saddle on your ass so I can keep riding it.

You know -- the new fuels do like to eat the old style rubber parts.... so the diaphragm in the fuel pump --- or any rubber lengths in the fuel system -- maybe a short length from the tank to a hard line or? Sometime they APPEAR fine from the outside but are shot on the insides...

ASSume all the spark plug wires have been looked at.... where they might be fine at low rpms and power ranges until you put the boots to it. A quick check I've done is to wait until dark -- pull into the garage with all the lights off - and fire it up and open the hood... and look carefully for any arcing on headers - or a cracked boot to head - or ??

Plugs in good order?? Again they might be able to light off light loads but can't light the richer A/F ratios when the throttle is banged....

Valve adjustment? ASSume you're running solids....

Need to check diaphragm in pump, secondary accelerator pump diaphragm has been replaced, spark plug wires have been replaced with new, should probably check fuel line from filter to carb.

Spark plugs are new and looks like I can lean her out a couple sizes, solid roller......valves were adjusted two track days ago.......that's on the to do list under "Before you spend money do this"

Fuel pump pick up?

MSD boxes aren't exactly known as bullet-proof reliable so definitely can't rule that out. But typically don't they just have a major coronary and go to the grave?

.........new fuel cell installed.......and this problem occurred?

Car ran great at Sonoma after all the recent changes Sieg. When I brought her home from Sonoma she sat in the trailor for a couple of days and then I took her to a local shop for a rear gear change.
Noticed issue after the shop made the rear gear change.
