I just got back from VTR (1800 miles total) and whenever I got stuck in traffic and the temperature gauge started to hit 185 and higher, I flicked on my 12" Kenlowe 10 blade shrouded pusher fan on my TR3A. Several times when the traffic stopped for 5 minutes or more where 2 lanes narrowed down to 1 because of construction and once (2 hours) when a semi-trailer rolled and blocked both lanes, the temperature stayed at 185, but I'm sure the engine compartment got hotter than normal. When I'd get going again, the engine would stutter or sound like it was running on only 2 cylinders during normal or hard acceleration. Feathering the gas pedal helped a bit and after about 2 minutes, it was all cleared up and running as it should.
A friend with a TR4 told me he has the same problem.
I suspect that the addition of 10% ethanol is creating vapour lock and after 2 minutes driving, the cooler gas is now getting fed to the float bowls and the problem disappears. I have never had this problem in Canada where we don't have ethanol in our gas. And I never had the problem before with US gas during trips to USA.
Any comments ?
