Fitting cowls

Cowl - noun. An infuriating object that takes hours to construct. Once completed in all it's pristine glory it will steadfastly refuses to fit. Once it IS fitted all attempts to remove it, access the needle valve or any other part of the carburettor will not work. WARNING - trying to tighten engine retaining bolts that you wire locked, used thread lock on and finally welded up will defy all attempts to re-tighten. IF you do succeed be aware that as soon as you refit the cowl the bloody things will loosen up again.
