Re: 1948 Iron 4G Coil Ignition

Chris, regarding float chamber filling. Obviously you have fuel in the float chamber, because you have cracked the starter jet plug and seen it, but can you verify that the starter well (which is above the jet) is filling? You will have to remove the float chamber and manually fill it to see the fue...

Re: 1948 Iron 4G Coil Ignition

This still sounds like a carb problem to me, although I did have some spectacular problems with the coil ignition on my own 1948 4G from time to time. As one last check on the Solex carb, have you undone the 4 screws which hold the float chamber section to the rest of the carb? This joint is vertic...

Re: Twist Grips

I'd forgotten about that post Alan, though having read it again I realise I have seen it before.

I'm pleased to see you have been down the same road!

Twist Grips

Folks, Twist grip lengths. I have some horrible repro rubber grips, about 5" long on my civilianised W/NG which I am about to ditch (the grips, not the W/NG); my 1951 SQ4 has original Amal grips of about the same size. Various canvas grips I've seen, used after 1942, appear to be about 6" ...

Re: Idle W/NG

No - I can close it and if the throttle stop is high enough and the timing advanced enough it will still run. Actually it will idle pretty quickly with the throttle shut if it is advanced enough. I'm beginning to think I am chasing ghosts here. In my view, it ought to idle relatively slowly & re...

Re: Idle W/NG

Thanks for putting that together Alan. I had a look at that today as well, and now I'm not sure if the needle really does contact the bottom of the drilling, although I'm sure it comes close. I did some measurements of port and and screw, which doesn't conclude anything; I also put some engineers bl...

Re: Idle W/NG

Screenshot_20190810_003656_com.android.chrome.jpg I am harbouring a fanciful notion that this Amal air screw has a shorter taper than the one I have fitted. IMG_20190809_161602.jpg I'm wondering if my air screw bottoms out against the brass plug and does not meter properly. Adding to this thought i...
