I'm working with a guy who's problem has me totally stumped and I was hoping that some body here might have experienced this before.
74 TR6
130# all cylinders on a compression test
timing is 4 deg after TDC
Fuel filter was changed
needle and seat valves were changed
engine has spark
The engine runs roughly and stutters and backfires. He removed the air cleaners and says that when he places his hand over the rear carb intake that he feels suction and the engine stalls, when he does it on the front carb, he feels no suction and the engine runs smoother but his hand gets covered in raw fuel. He's checked for vacuum leaks and intake blockages and found nothing.
What am I missing? Any thoughts?
