Well it all went a bit wrong on thursday night, went out to buy some stuff for van jambouree only for the throttle linkage to come away from the pedal on the way home. So with some creative use of zipties I limped the van back home.
So I didn't make it to the show and saturday I was at the workshop fabricating a new throttle linkage.
Ok, so this was the problem...
As its cast ally I couldn't weld it so this was my solution..
My throttle has always been really stiff and as documented in the thread, the floor in this area has been replaced and the throttle linkage bracket welded on to the new floor section.
Looking at the way everything sat I didn't think the linkage needed to be offset like the original so I decided to fabricate one.
I was also struggling to get full throttle, this I'm sure was down to the linkage being bent so I made mine a lot beefier and drilled the holes to give me a little more travel on the pedal.
All fitted up and it works a charm. Full throttle and easy, smooth pedal operation.
