The problem with Amazon reviews and evilpay feedback is they are time limited
So for instance the GX 25 carb a customer gave me to fit last year has now packed it in after 10 months.
It has a defective check valve but the customer can not go back now and say these are defective ( wrong rubber used )
And his vendor had a 5 star rating as well
Ijabe fitted one of my carbs, from a reliable supplier who gives me 12 months warranty and it was only $ 11 more than the junk carb + $ 90 for two services .
