69 340 AVS fuel leak

I ran my SB both ways, without the exhaust heat and with it. Motor seems to run better with the exhaust heat-expect when its over 80 degress outside-here in Michigan thats not too often, even mid summer at night it cools off to the mid- 60's.

I always use a thick gasket under there carb thou. Never had heat problems-other than having to crank the motor for 10-15 seconds before starting once in a while. A small price to pay for have a motor that warms up nice and fast.
