Hi all,
Fred's question and the great responses couldn't have come at a better time.
I'm working on a customer's LeMans I carbs and boy are the float levels way
off! That will definitely help with it's running problems, but I'd like some
input on the jetting as well. Here's a comparison of what I have listed as
stock and what is currently in the carbs:
Needle - K5, 2nd (middle) groove
Slide - 60/3
Main jet - 140 (stock 135)
Pilot jet - 50 (stock 60)
Starter jet - 70
Atomiser - AB265

The heads have been ported and polished, the manifolds cut and straightened,
K&N filters, a custom built exhaust with MAC mufflers and a Dyna ignition
firing car coils are installed. Seems to me with the mods it has, the pilot
jets could have stayed stock without being too rich. Ideas?

While I'm already off topic, let me add that the above mentioned LeMans I is
for sale. It's sporting a monoshock rear suspension, modified front forks
(supposedly with Marzocchi damping rods inside), custom-made fork brace and
has been somewhat lightened (parts deemed unnecessary by the builder were
removed). Needs some TLC, owner is asking $3000. If anyone is interested,
I'll pass his number along to you. Thanks!

 Anyone know the correct float levels for the PHF 36 pumpers off a LeMans

17-18mm.
