If I remember correctly it was about 36-37 degrees. Dan, I'm planning on going
to Pueblo. Don't know about Neb. yet.

Here's one from left field. I had a similar problem on my TR4 racer. In my
ase the ignition was a couple of degrees too far advanced. When the car got
ot it would sputter. Slow down for a short time and it would clear up and
un
ine for a few laps. Drove me crazy for a long time. Turned back ignition
problem went away and never happened again. Same thing happened on my
uddies
GB racer.

'm getting some well-thought out suggestions. Thanks to Michael P, Bob K,
m M, Jim G, Tony (TR4 Tony), Russ M, Irv K, Scott B, Chris, and Bill B.
y thoughts that it was fuel related seem to be supported by the fact that
st of you mentioned fuel issues. So far:
Bowl vents clear? Hmm -- we do have mud dauber wasps around here!
Fuel foaming due to vibration? (X2) Possible, and perhaps the new
anifold
ace could add more vibration.
Sticky float or float needles?
Leaky floats?
Resonance due to new brace causing jets to sink down? (They're supported
y
spring, but it makes sense that resonance could cause the spring to lose
nsion temporarily, the way a spring governor on a lawnmower engine does)
Needle(s) not properly seated in piston(s)?
Advance profile poor or advance mechanism sticking?
Loose engine ground cable?
Improper jetting for driving style? (Perhaps, but this didn't happen at
S and seemed to get progressively worse at ECR even as I tried to prevent
e problem by braking later and sometimes holding throttle pressure while
aking)
. Bowl lids (ie: float hinge point) oriented improperly)? No -- this one
s been checked. The suggestion came from someone who was also asking
ether it happened more when turning one direction and not another --
rection did not matter.
. Dirt in carb? (X2) Fuel filter was clear when checked on Saturday but I
ven't looked in the float bowls yet. I'll blow the lines back to the fuel
ll (no rust seen in fuel cell when I cleaned it out a few months ago --
und silicone worm scraps, though)
. Oiling plugs?
. Intake tract leak?
he suggestions will guide my investigation -- thanks, everyone!
