Ron, that was one of the best rides we've done in a long time. I loved the
figure 8 route using different roads all the time. I'm probably going to
use that route for another ride in the future. I'm sorry we got to miss
Greg wielding the wrenches and analyzing the problem with John's Lotus. I
think Greg is one of the most talented car enthusiast I know and willing to
share information all the time. We had already bought sandwiches and so
went off to Kendall Jackson with Norman and had a great picnic in their
beautiful grounds. The turn out was great you might want to think about
going back to Sundays in the future for the second ride.
Great day and happy 50th. for you car.
Andy

Hey All,
That was a great drive today, and what a nice turnout! Thanks Ron for a
great job keeping us all in a tight group. It was also great to see the
newer members and get some new cars on the drives.
For those of you who did not attend and those who didn't stay through
lunch to see John having troubles starting his Lotus after lunch and the
subsequent resuscitation, I thought it might be useful to share with
members who may not have gone through this before.
After cranking with no throttle to no avail, Walt and Dennis suggested
open throttle, so we tried 1/2 and wide-open, both to no avail. After
verifying we had spark and the fuel pump was working, we saw that the
fuel filter in the engine compartment was almost completely empty. We
were smelling fumes and assumed we had fuel flow, but the engine
wouldn't even cough. A check of the plugs showed no fouling. Finally, we
removed the air filters and with John propping up the Stromberg's air
valves 1/2-way (constant-depression carbs won't draw up the pistons,
even with throttle butterflies open, until the engine starts sucking
air), we cranked with 1/2 throttle and the engine fired up.
When I lived in So Cal I had an MGB that would cook off gas in the fuel
bowls on hot days when parked in the sun, even cooking off fuel in the
engine compartment fuel lines. I'd smell what I thought was gas, but was
only fumes, and would sometimes not be able to get the engine going
until it had cooled enough to clear the fuel line vapor lock and/or fuel
bowls. That's what seemed to be the problem today. It was quite a hot
day, John's Elan is painted BRG (dark color), and it was parked in the
sun. After moving it to the shade, cooling it down, and getting the air
intakes open, away she went. The fix for my old MGB was heat shielding
on the engine room fuel lines and SU fuel bowls; John's will be cutting
two vent holes in the inner fender well, a modification Lotus employed
in cars built after John's.
Have a great week!
Greg and Trish
