I received these 14 days after ordering them. It only took 2 weeks to get them here into Ontario, Canada. I have ordered q-jet parts and asked for advice from here before and my experiences have always been very positive. This experience was no different. The quality, fitment were top notch. Not to mention the cost was very reasonable, even after the exchange rate was calculated. I asked them to advise on the proper size of these for my Rochester and they were spot on. After install, I adjusted them to about 2 full turns with each of them. I’ll probably need to fine tune them as time goes on. I definitely would not hesitate to continue ordering carburetor parts from Quadra-jet Power. Thank you.
