87 carb on 79 2F

[John Smith]

I am installing a 1987 FJ60 carb on my 79 2F and need help with the connections as they vary greatly from my 79 carb. The 79 2F is fully desmogged.

A Idle Mix?
B Advancer Port for dizzy?
C ? CAP
D ? CAP
E ?
F ? CAP
G ? CAP
H Choke Breaker, Leave hooked up as from factory
I Choke Opener, CAP
J ?
K Goes to Evap Cannister
L AC Idle up, CAP as I don't have AC

bump, I really want to hook this thing up.

Does the 79 have a fuel return line? If so, what are you going to do without the return fitting on the carb?

I'm just curious, since I briefly entertained the idea of running an FJ60 carb on my 40.

 

[John Smith]

The 79 does not have a fuel return line on the carb. It is on the fuel pump.

A Idle Mix?
Yep.

B Advancer Port for dizzy?
Nope. Decel fuel cut port. connect to decel fuel cut switch.

C ? CAP
nope, ported vac to dissy.

D ? CAP
Yes, HAC is bad.

E ?
Choke hi-idle screw. Adjust to 1800-2000RPM w/ choke on, engine warm.

F ? CAP
G ? CAP
Yes, more HAC, cap em both.

H Choke Breaker, Leave hooked up as from factory
Yes.

I Choke Opener, CAP
Cap if it makes you happy. It's a vac sink, not a source, so doesn't need capped.

J ?
Base idle speed screw. Set to whatever you like w/ engine warm.

K Goes to Evap Cannister.
Yep. It's a good thing.

L AC Idle up, CAP as I don't have AC.
See I, above.

Be aware that the 81-87 carb is shorter, so won't seal up w/ the air cleaner lid properly.
And the choke cable end is different, so the stock 79 cable won't hook directly to the 81- choke arm.

Later, gotta get back to work.

Thank You Jim!
