Re: Holding clutch in and oil supply

The hydraulic clutch conversion fitted by Richard Negus to my Supreme Commander is certainly a bit easier to operate than the cable one. But, for a small handed guy like me, it moved the biting point even further out leaving me working it with the tips of my fingers and a seriously stretched hand. L...

Re: Indicator problem.

Re: Bending plexiglass headlight cover

As you have an original glass cover the bend could be roughly checked against the glass one by laying it against both outside and inside. If the perspex cover is clear of the glass one in the...

Hard to use too much loctite as any squeezing out of the joint doesn't go off. More likely to be the wrong grade. The high strength varieties are strong and bonding area in a thread is considerable.

Re: Su float bowl needle

When the float is lifted by more fuel flowing into the float chamber it compresses the spring which pushes the float needle up onto the seat shutting off flow when the maximum level is reached.

Re: Su float bowl needle

Trevor You are overthinking this. When the carburettor is inverted the float needle rests on its seat and the spring compresses just enough to support the weight of the float. So long as the float sits at the right height the fuel level will be correct when installed. This is just a set-up test. Whe...
