n August of the hot summer of 2019 (aren?t they all hot now?) I put Evans i=
n a Tiger which has an excellent two row aluminum radiator in front of a ra=

the TEAE United and then Route 66 on the way home. Temperatures were frequ=

The carb got so hot the fuel percolated (boiled) inside the bowls and the e=
ngine stalled lean. This weakness was exacerbated at altitudes above 4-thou=
sand feet. In Pueblo, with OATs near 100 I ended up on the same AAA tow tru=
ck twice on the same day. I then gave up and reluctantly drained maybe half=
of the the costly coolant out, replacing it with plain water so I could ge=
t home. However the percolation reoccurred crossing the Mojave in the 115 d=
egree August temps. At home I replaced the Evans with water, adding Water W=

like .65 or only 2/3 that of water. For me, Evans just did not do the job.=
From my experience I?d say one would have to be exceptionally brave to use=
it, especially with a stock radiator system or with a more powerful engine=
which will place even more demand on the Tiger?s weak cooling system. (BTW=
in the Tiger we drove on that trip, we had removed the stock block under t=
