I want to get rid of the SU type carbs. I have 3 MGs and have had many more
for 30 years. I need or shall I say my woman needs?/wants a dependable
sports car. She has a 1986 Honda Accord and a GMC 1 ton van. She keeps
getting stranded and I have to go and get the car running. By the way the
car has a after market tube header, medium lift cam. I have been building
small block Chevys for 3 decades also. I shoe-horned a 302 ci (327 block
with 283 crank) dual quad tunnel ram, 12 1/2 to 1 forged pistons, 202
heads.....you get the picture into a 1954 Austin Healey 100-4 and a similar
engine in a 1964 TR-4 both tubbed with a 9" rearend.

I need a "child proof" carb system. I am also looking for metering rods as
one is bent and the choke piston sticks. Car is very hard to start. I am
thinking since the breathing has already been updated a Weber system might
be the way to go.

Does the Weber or any other carb have an accelerator pump?

David,

SUs, in good condition and setup properly, are far better for street use and
much track use than Webers or Solexs. That said worn out SUs like I have on
my '70 2000 aren't so hot either, as you've found out. However, don't expect
to simply stick a set of totally different/usually bigger carbs on a stock
motor and have your problem cured, because they won't be. Get a good set of
SUs and get them set up right. You won't regret it.

for excellent SU info and remanufactured SU sets.

HTH,
Ron
