Throttle cable slack
Another daft question..
I rebuilt my Amal 376 carb which is now back on. One job led to another & I ended up replacing a few things.. fuel lines, HT lead pickups, throttle, ignition & air cable.
Despite a fuel leak from the air float chamber (gasket must've been seated wrong), everything seems fine.. bar the throttle cable..
I've kicked her over & she fires up first time but there's a good inch or two of slack in the cable. It's got the adjustable section so I've wound that right out but it hasn't helped much.
I ordered the cable from AMC & she swore it was the right one.
What's the craic?

It was £14.95, so I assume it was the monobloc throttle control cable with adjuster, doesn't specify a length though & I can't measure mine as it's now on the bike.
I'll ring up on Monday & enquire.

Re: Throttle cable slack
You only refer to the mid way adjuster being fully adjusted to take up free play. What about the adjuster that fit's in the top of the carb ? Which you should have. I assume you do have the loose split collet, if that's the name for it, at the twist grip end.

Re: Throttle cable slack
I haven't yet adjusted the top of the carb to take some of the slack up, I'll try that tomorrow.
The split collet is there yes.

Re: Throttle cable slack
Hi Luke,
If as you say there is an inch or two of slack in the cable no adjuster will take that out, I would speak to AMC Classics and if it's their fault they will replace it, I have always found them very helpful, and "she" her name is Linda by the way is very knowledgeable about all things AMC just like her son Steven.

Re: Throttle cable slack
i think the standard cable will have an inner that is 3" longer than the outer in order to fit and require minor adjustment .

Re: Throttle cable slack
It certainly would have. Which is why I questioned about the carb top adjuster. Which it was said had not been adjusted. So perhaps we need to start at " fitting the cable " Wind the carb top adjuster fully in, fit the cable in the carb. In the very first instant this will take up most of the 3" free play, provided the carb has all the parts, like the long spring between carb slide & top. Having done this the spring will hold the carb slide in the fully closed ( down ) position. Next fit cable in the twist grip. Adjust the free play via the carb top adjuster. Just in case this fitting procedure has not been followed. Check this has been done, also the carb slide has not stuck in the open position, so leaving a lot of free play.g5wqian wrote:i think the standard cable will have an inner that is 3" longer than the outer in order to fit and require minor adjustment .

Sorry, she, the cat's mother! I'll give Linda a ring today & find out if I was posted the wrong cable. She sounds very helpful.cbranni wrote:Hi Luke,

I've wound both adjusters all the way out but I've still got an inch or two of slack.Rob Harknett wrote:It certainly would have. Which is why I questioned about the carb top adjuster.

If I manually take up the slack by winding the throttle grip round & then kick her over, I can rev the engine up nicely, so the throttle carb slide operates well & isn't stuck.

Re: Throttle cable slack
Hi Luke,
You do have a split conduit stop fitted like this in the twistgrip (excuse dirty finger)
