| Re: \'Bowl Trays\' & Flame Arresters
Hi Fran,
I'm not sure what designation the valve covers came under but I will look into your sugesstion. FYI ONLY - The Dish tray around the base of the carbs is a pelenium chamber shut out panel or bowl tray is an ingenious device that has two fucntions: One is to shut the lower engine area away from the air intake pelenium chamber and therefore draw on clean air brought in by the side intakes. It also keeps hot air rising from the motor itself and the exhaust system which is usually running at 450+ degrees when racing!
Sometimes cars have a rubber seal on the edge of it to seal against the underside of the body to shut any hot air getting up into the fresh air area.
The panel on top of the carbs is a flame arrester. The webers have a tendancy to spit back (especially IDAs) and flame up the carb and there is little to prevent the flame jumping back. If your not wearing an air filter, then the cough of fuel back up against the window (plastic!) can be set light! The main jets have owners set the jets too high or they have the fast idle set too open. This even on throttle shut down, allows unused fuel to wash the bore, which can detonate and either spit back or worse, blow your motor, usually by ring failure and scoring on the bores.
Just a heads-up.
