Re: 1970 Longhorn “build” of sorts.

Thanks for the info on the cruise. Parts had been removed before I got the truck, but I can get it all sorted.

Also spent the last 2 afternoons playing with the engine. Set the timing, check the vacuum advance etc. Had it all sorted, it has a pertronix electronic ignition, new rotor, cap, leads, plugs etc, so it runs great, however it was pretty slow.

So today I dug into the carby, setting the choke, as it was slow to come of, checked fuel filters etc.

Then I check for full throttle travel........ Not even close.
With the pedal held hard to the floor, the primary butterflys were 2/3 open, secondaries not even close to moving.
It has new secondary vacuum actuator, and all appears to be good. Just no throttle.

So I removed the rod and shortened it by almost 1" and mounted it in the top home on linkage.

Now we have opening secondaries. It goes like it is supposed to now.
It even accelerated in a mild hurry up my test hill.

Not sure what position it is supposed to be in, but it's 1000 times better than before I moved it.

I am happy. It is starting to get there, just need to sort out the locking rear brakes.
