Need help for friend who is not going to be around long

aengineguy said
I really need some suggestions. I am a Mopar guy, but my buddy has a 69 big block Chevelle and I am stumped. It has a Q-jet with automatic. When rolling about 40 mph in 3rd and you barely increase the throttle it starts stumbling and even loses all power until you back off the throttle a bit, not backfiring. The engine was recently went thru, he put a reman Q-jet on from Summit and new Pertronics ignition. I have been doing cars for 50 years, and cannot figure it out. He has Lou Gehrig's disease and is the point he cannot even talk now. We are going to Carlisle this weekend, kind of a bucket list thing. Appreciate any thoughts!

Man I feel for you.... Unless he can overcome what I have seen 2 people go through with the disease, a clock is not his friend. So be steadfast in finding the problem. If you suspect the carb find someone who will put it on their vehicle or maybe borrow a known good one.... But you can also make quick work of checking fuel pressure and all the other basic gearhead steps. It's tough to give an answer with much accuracy and if you were near me I would be more than glad to help get you in a direction......
