Spent Sunday afternoon attempting to sort the throttle cable problems. Along the way I have found a problem with the carb re-assembly.
I guess this should be problem 10 on the list then.
This ones home grown, but not surprising as carbs are my weak point. Was hoping I had it right first time on this one. Anybody that followed my 750F2 build will know that the carbs on that were on and off so often I could do it in my sleep.
Anyway, for some strange reason the carbs are not closing correctly. Meaning that the cable quadrant is not rotating back fully. Not sure what it is, so rebuild number 2 is about to start. Whilst I'm doing it I am going to change the worn quadrant for a spare I have. That should correct the problem of the cable not being retained.

You can just see in the picture that the throttle stop screw is right out and there is still an gap of about 10mm. This has the effect of making cable 'A' appear too long, and cable 'B' appear too short. The over-return stop is also miles off the quadrant. Not doubt when I get back in there it will become obvious whats wrong.
Second problem with the carbs. Although they were carefully cleaned and rebuilt with all new parts, 3 out of the 4 carbs are deluging petrol out of the overflows.
Engine start is now put back again. Never mind, nearly through the extra challenges now. I would rather have everything done correctly before I attempt to start it.
Cheers all.

You havent got the adjusters too tight have you ? got the tee shirt for that one
royhall:
Yep agree with you Bryan. It's probably a setting issue but got to strip them again as the quadrant, where the cable bobbin locates, is so worn that it wont hold the cable in. Didn't notice it when I was doing the carbs or I wouldn't have bothered getting it re-plated. Not really the sort of thing I was looking for. Never mind I will get there in the end. Cheers.

Hi all. Been a while since the last update. Have had to remove and rebuild the carbs a second time. Also had to change the cable quadrant as it was worn out. Well that's all done now and the carbs are back on the bike with the cables fitting perfectly, and the petrol staying where it should be. BryanJ was right it was to do with the setting up.
Sorted a few last remaining bits and finally its time for engine start.
Just by chance Alan (Mctid) was calling round with his 750K4 engine so decided to wait until he got here before the big event. Somebody to man the fire extinguisher. ;D Anyway now Alan the 'glamorous assistant' has arrived its time for the main event. I would like to say I wasn't nervous but that would be a lie.
So here it is, give you all a good laugh if nothing else.
