...drama?

My case right now:

Griffith 500 in good order, engine rebuilt, a few solid mods (triple plenum, larger AM, Marks's chip, sport decatted exhaust, new plugs, new battery)...it starts and keeps the idle with grace, smooth like silk....problems start when warming up, the engine does not rev happily, you can feel at the exhaust notes of boom bam releasing the right pedal and a strong smell of unburnt fuel.

The cherry on the mountain of s....the engine might suddenly stop altogether at once and without any prior sign...all these peculiarities happen when the engine warms up, still it keeps the rumble at idle, but when you want to put down the right pedal all sorts of malfunctions start to wake up and the engine gets crazy, the engine does not pull.

I need help here, really.

Thanks in advance.

What if it was the cable into the AM, I'll clean it with forced air and will post the results.

Thanks for all the contributions and inputs.

My Griffith is decatted since day one...

Today I've cleaned the plug into the AM and have unplugged the EU box for a couple of minutes, the engine seems run smoother.

Anyway the mess that there is in the EU box + battery area is incredible, I'm really thinking of swapping in a nice quadruple carb and dump the whole tons of loosing cables away and get a cleaner set up.

I might get some money from my triple ACT carbon plenum plus ancillaries to pay me a new carb.
