Re: help sq 4 wont run

Just to add a bit more to this crankshaft sludge thing. I've even found a prewar single with the extra small pipe (as original) fitted, but completely blocked up. I also have a twin KH that is all lovely and clean and shiny down there inside the bottom end as I bought it but I won't be running it ti...

Re: help sq 4 wont run

The slide Amals don't like a steady suction that a four provides. The slide action is often sticky. Best to have one carb per cylinder with an Amal. Re the sludge, DON'T run it, even for a short period, and flushing oil is from the dark ages when engines had dippers to pick up oil from an oil bath. ...

Re: solex - poor mpg

Don't add weight, use a fibre spacer. As the seat and needle end wear the fuel level rises any solder repairs add weight also. Sometimes the float only "just" floats. those carby's get hot. If the fuel gets bubbles in it the float sinks and then you really get through the fuel. Nev

Re: Cleaning oil tank

On one bike it was 1/2 inch solid on the bottom (at least) and I had to dig it out with a screwdriver, first This bike was professionally painted and restored before I acquired it, many years ago. A 1951 VH rigid. After the digging and scraping, put the USUAL old 1/4 roller s and roofing nuts (squar...

Re: solex - poor mpg

IF you add weight it won't work well and will make it richer. Vibration can affect this function.( Higher frequency). The carby might be getting hot and venting a bit off or if bubbles form, the float sinks and allows more fuel in. Nev

Re: WNG Magdyno

Gees Luiz, you must be strong. How did you lift it onto your desk?. I thought your camplate had the extra notch, making it suitable for either method of cable operation. Your engine will run just as well no matter which way it operates , if it's free to move over the whole range.. Nev

Re: solex - poor mpg

Put your finger in the end of the exhaust pipe(s) and feel how much soft carbon is there. (not when it's still hot of course) It will be pretty evident if it's rich... Then check float height and jet sizes etc. if it's sooty. An individual "type" of carb is rarely the culprit on it's own b...

Re: FOR SALE Black Ariel

The 1929-on 500 OHV black Ariels are just as fast as a 1950 model 500 OHV. It's just they have hand change and 3 speeds and everything , (chains valves etc) is in the open and needs looking after, especially if you are in dusty conditions where it's useful life will be considerably reduced, if you n...

Re: Simes' FH Rebuild

I would question the need to use Loctite at all in this situation. It's on no great load and doesn't even have to seal perfectly. Just be sensible with the amount of tightening used and have good clean threads and make sure the plug bottoms out OK. Move it in and out a few times to be sure it's goin...
