Fred,
You have been a big help to me over the past couple of months. Much
appreciated.
First, what I meant about wishing the TR-3 having a real choke was that
most cars have a 'butterfly" that literally "chokes" off some of the air at
the mouth of the carb, giving a richer mixture. Correct me if I'm wrong
but as far as I can see, all this one does is give it more gas. I will
check the float housings to see that the grose jets have only one gasket --
I installed them a coupla years ago and don't recall. Also will check to
see that the arm is bent per your instructions. I don't believe there is
any gas getting in the oil, it's not diluted. Please clarify, in simple
terms, what you meant about the jet coming all the way down when I pull the
choke out. What I don't know about carbs would fill volumes.
The way I start the car cold is this: 1. Yes, I prime the fuel pump to
fill the bowls.
2. I pull the choke all the way out. 3. Turn it over. For a long time.
Finally, it tries to catch, but doesn't. Turn it over some more. Push the
choke in half way. Turn it over again, and it usually starts running after
a while. Big strain on battery and starting motor. I'm unhappy. The car
is unhappy.
This morning I reassembled the rear brakes after replacing rear pipes and
all three flexible hoses. I put the woven stainless steel units in from
Moss. Looks great. Sometime this weekend I will get someone to pump the
brakes so I can bleed them, and that job is done. Then I'll start on the
float chambers.
