Ripped off
I hate to hear of the problems. I had David redo several carbs for myself and a couple of friends in the past. He did have to redo 2 of them. One had a problem with the secondaries hanging open and flooding the engine. I sent it back and he had quite a time with it. He said he had to test it on a friends car a couple of times to get it right but it worked awesome when i got it back. I let the other one sit for 3 years before using it so I can't totally blame him for it's problem. He did fix it though.
I have another one I will need rebuilt if I ever install my 400 in something but I will look for current feedback before sending it to him. Unfortunately it sounds like his quality of work and customer service have gone downhill since I used his services last.
