O.K still trying to get to the bottom of the poor running...
Now i'm no expert with this type of early fuel injection, but I have to say I am really enjoying learning and fathoming out how it ticks. As previously explained, i'm going through each component and stripping and cleaning to see if I can have a 'Eureka' moment. This even now has not happend, but I keep finding lots of little faults which you think must be it, but alas no beer!
So this weekend I have stripped the throttle body.
So behind this little black box is the stuff that can play up! I buzzed throught the contacts and found one on the idle side of the track not working.
Cleaning with a good contact cleaner and some carefull use of 2000 wet and dry sorted that out.
You have to be very careful and use a delecate hand with this stuff.
Still amazing that this is 42 years old!!
So now we have everything working and a nice '0' resistence
:thumb:
So I re-asembled it all back up and fired her up.....Still the bl@@dy same :bonk:
Well one down and all that...........
The next thing on the list was to replace the thermostat cable. This cleaver little bellows expands when it reaches 90c and shut/opens (Not sure which way around it works) two flaps that are shut when cold to allow the engine to warm up quickly.
With this snapped the engine can overheat. Theading the new cable up through the tinware and around a pully was fun. I have to get Mrs Chief to help out.
So with this one ticked off the ever growing list I moved on to the distributor. Getting this little bu@@er out was fun. I honestly cannot remember the last time I got involved with stripping one. It must be 25 years ago easy!
So someone has put electronic ignition in and replaced the points. But the interesting thing is in the bottom of the distributor is another set of points that trigger the fuel injectors. Very simple but effective. The unit just pulls out.
I gave these a good clean and removed the old grease which was more like wax after all this time. The points base rotates against it's self to allow vacuum advance. The plate was tight so I spent some time cleaning and re-greasing. Also the little earth wire had come adrift.
On assembling everything back together I realised that the electronic ignition trigger was tight and slowing the vacuum advance. So I filed it's base plate to free it up. Now I thought all these little things must add up to something. Well put it all back together, but not having a timing light anymore (Like who has nowadayz) I put everything back to some whitness marks I had put on at the start. I figured i'd get it running and time it by ear for now. Well turned the key and it won't even run now :grin: i'm getting good at this mechanic stuff don't you think?
Anyway, I thought i'll leave it for now and go and see PeterS for a coffee and catch up. I'll look at it with fresh eyes next week sometime......no rush, still lot's to do to The Red Baron :roll:
Well no further forward, infact further back than before. Until next time.
Peace out from PROJECT BLUE BOOK.
