I wish my first post werent of this type, but my frustration has gone far enough. In any case Hello! Im a proud owner of TR3 driver car. Nothing perfect but fun
Now on to the troubles... :wink:
I was having issues with an old Grose valve sticking in the float bowl of my TR3A. It was sticking really hard. It has the stock, likely original SU carbs in it with the side bowls.
I purchased two new Grose valves from Moss, one as a spare and replaced it. I noticed they both seemed to stick a bit, but installed the one that felt the loosest. I took the car for a short trip up the hill (incase it dies its easier to coast back home!) and sure enough it stuck again and killed the car. One bowl with a new valve is empty, the other is full. The old grose valve in the other carb is very free and never sticks.
Fuel pressure is about 2.25 psi with a hot engine from an aftermarket electric pump long ago replaced by a previous owner. There is no pressure regulator, just an after market strainer and filter which are both clean. Fuel lines are new, not kinked, and have been purged with cleaner and compressed air. No obstructions in the bowl lids, fuel lines are insulated, and im not vapor locking. The lever on the float bowls have been set to 7/16" per tech instructions.
Suggestions? Should I contact Moss about the parts? Ive been thinking of replacing the fuel pump with something a little higher pressure to force the valve open but i dont want to band aid it.
Thanks for the help guys!
Cheers,
Milan
