The only bad thing I figure is that the back tires life will be shorter now... My first ride with the E carb, Man am I impressed, If I had rode a BRP with the stock carb and then one with a E carb, The E carb would have been one of my first mods.. I know how the stock carb would pop and burp at times pinning the throttle on a qwik take off, Not today, takes right off lifting the front tire so much easier, No more stalling on steep hill climbs with a sudden stop.. Had a small tip over ,The stock carb would have flooded needing to kick over to clear its lung, My son comes over and says, Well heres the test, Fires first kick we were all in awe, Way cool...... When I start it cold, 2 blips of the throttle and first kick she lites off, never before.... Riding today with the E carb made me feel more confident in riding without a concern of it dying...... I've read some of the search history here and cant believe the negative talk .. Oh well, In my book the E carb is top of the list......... This is how a four stroke should run... Plus I like how Edelbrock used allen head and torx screws instead of philips.
