my girlfriend has an 87 with the howell setup. it works pretty good, but every once in a blue moon, it floods on her, and i have to go mess with it for a bit to get her fired up (the jeep). one thing you dont want to do is give it ANY gas when trying to start it. it seems like if you do, it keeps dumping it in. i dont know if they are all that sensitive, but i have looked it over and everything seems OK. it runs perfectly though, other then that. starts up great in the cold (usually). its a lot nicer then the carb.
hers already had it when we bought it, but the install should be relatively strait forward, nothing real goofy or anything. it seems like it uses mostly all gm parts wich are readily available in case of trouble.
