I don't know what it is about Holleys that makes them so troublesome, new gasoline formulation that causes leaks, excessive drying out due to heat or storage, bad float design, etc., etc., but they just don't work well long term, without at the least fiddeling with them. When I got my Imp it had a Holley that needed constant fiddeling, so I fianlly rebuilt it and did a major tune up, and the car ran great, would idle down to almost nothing! Shortly thereafter made a ten hour roundtrip to Lowell Howe for some parts, getting 14 plus MPG, then parked the car for about two months while it was being worked on. The car would never run with the Holley again, wouldn't even start, and leaked like a sieve! Thats when it got its Carter, that hasn't been touched since I initially rebuilt it and it was put on. The car will start after three days or three months of being parked! I have never been able to get it to idle down as low as with the Holley or get as good gas mileage, but the trade off has been worth it, IMHO. Roy 67 Crown FDHT
