accelerator springs on linkage... ?

Postby jethro » Sat May 21, 2016 8:34 pm

I am wondering if the external spring on the linkage gong to the fuel pump is needed....
(the coil extention spring which runs from the tab on the gear case to the control rod)

I tried it arround the yard without the spring on - didnt feel anything negative- seemed to come back down
to idle OK without the external spring. The force on the pedal felt more like I am used to. With the extra spring hooked up
I seem more consious of how hard I am pushing the pedal down.

1. do i need the extra spring

2. if I do- where is the best place where it should hook in- ( I am still using the bellcrank that used to have the cruise control
on it )

(I have used a cable -in-tube type throttle cable- taken care to run it close to perfectly straight so to reduce friction
to a minimum )

thanks-

Only thing I noticed with the timing cover to throttle lever spring removed is that the throttle will have a tendency to flutter when hitting bump on rough gravel roads and such.

I would run it just for my own piece of mind. It hooks into a hole on the timing cover and then to the upper hole in the arm above where the throttle rod attaches.

I have a regular gasser return spring on mine. It seems to work ok.

Just enough power to break everything behind the crankshaft.

When I moved the knob on the IP lever to the inside it was stiffer from the change in leverage. So I took the spring off for a bit.
