As some of you may remember, i was considering a couple of months ago to convert my 2000 TC from twin HS8s to twin HIF6s.
I did not had any particular problem with the HS8s. A couple of years ago i rebuilt them changing with new parts anything that could be changed and i matched the pistons for falling time. They were running fine, the idle was reasonably stable, they turned up decent economy and they passed the emissions test every time.
But i always thought that they were rather oversized for a 2 litre engine and i was tempted to try a pair of smaller carbs as fitted to the 2200 engine.
An almost complete set have been sourced, and even though they looked filthy, they turned out to be rather healthy. Shafts and throttle plates were fine, but i had to renew all seals and gaskets, plus jets, needles and float valves.
Fitting them to the car was not straightforward. Due to the fact that the throttle uses a cable, i had to device something that linked the throttle pedal rod into the cable. I came up with something that although looks somewhat flimsy, works reasonably well, but still is not perfect. I would like some more leverage for a smoother action, but the space is rather restricted. The steering box, heater hoses, brake fluid reservoir and pipe are also crammed in there.
I also had to change the choke cables. There was no need to retain the complex twin cable system of the HS8s, but i wanted to keep the hooked choke control, just for the looks of it. I managed to remove the old wire from the rod, drill the rod and crimp a new longer inner wire. A lot of hassle really, and i am still not sure if it was worth it, but it works.
I still haven't connected the hot air intake system (i am also missing the cowling in the manifold) but i will try to do it later.
I managed to set them up without much trouble. The only problem is that it is a little difficult to reach the mixture control screw of the rear carb. It is rather close to the steering box and to make matters even more difficult the brake fluid pipe is also in there. I can just reach it with a screwdriver bit.
I did not had the chance to drive the car tonight, but certainly the idle is much more smoother, i would dare to say that it is as stable as in an injection engine. I will have to wait for real driving impressions though.
I will come back.
