satsuma catching fire - without getting hot

[insufferable-child]

in a newish save i replaced the stock radiator with the racing radiator, then a week or so later replaced the entire emissions system at once with twin carbs, steel headers, racing exhaust, and racing muffler. I saved after the installation and now it seems that I cannot drive much further than the rail tracks before the car catches fire.

here's what i've covered so far trying to figure this out:
- all bolts are tight, verified with MSC editor
- all fluids replaced/refilled. fresh oil and a full radiator
- AFR is within normal operating range. I've tried both ~14 and ~12 and it catches fire either way.
- engine temperature is not high, about halfway on the meter. coolant pressure is also in a nominal range.
- in a moment of frustration, weakness, and desperation, i even went in with MSC editor and ensured all parts were in good condition with ideal tuning. still catches fire.

so, i'm pretty stumped short of blaming it on a bug. have i missed a step somewhere?

is your water pump working correctly?

Upload your save so we can take a look.

Could be the headgasket blowing up and starting to burn the oil

same here but the headgasket was a little more worn. maybe msce is improperly reporting it as installed? mite tear the engine apart and put it back together.

just to clarify this save file has some msce changes implemented but the carb is untuned and runs at something silly like 16 afr

The problem was the pre wired subwoofer and speaker which cause electric fire.
Now i installed subwoofer and speeakers.

Also Alternator changed and checked wiring.
