Hi all Here is my tale... I got my car a few months ago. It needed some TLC. I picked up the Roe book on q-jets and using it I managed to determine that my bog was probably the power piston sticking. I managed to free it up and everything was great. I drove the car hard the few times I had it out to try to get the engine cleaned out. It was working perfect until I got it home and looked at my exhaust. It was obvious that I had a leaky head gasket. No antifreeze in the oil but there were a few oil spots floating in the coolant. I changed the intake/head gaskets. I did not pull the carb from the intake. During the time I had the intake off I had to hold it in many different positions (read-anything but horizontal!). Since re assembling the engine the bog is back. It starts and idles fine, tho the choke seems to be sticky now. I'm guessing that my flip-flopping the carb around probably loosened up some more gunk that was in there and is gumming it up. ou: I tried to free up the power piston again but it really doesn't matter. In fact when I decel getting off the highway I can hear a slight backfire (The driver side of the Y pipe isn't connected, just the passenger side) so I hear it on the driver side. 1) Looks like I have to bite the bullet and rebuild my carb (I knew it had to be done sooner or later). Is it fair to guess it is full of loose "gunk" now due to having to jostle it all over the place? 2) Would having only one exhaust manifold connected affect the performance? Thanks in advance! (My wife wondered why I didn't leave it alone until the spring. If I did all I would think about all winter was getting the head gaskets off!) :grin:
I have not looked at them but the carb wasn't off of the intake. Because of where I had to work on the car I had to hold the intake up against my chest and slide out past the car (with gas spilling down my shirt). I think that is the root of my problem. I likely unseated all the gunk that was in the largely untouched carb. I doubt the carb has been touched in at least the past 15-20 years so it is probably pretty grungy inside!
push the rear air valves open with your finger....there should be quite a bit of resistance. If they flip open real easy then tighten that spring and give it a try. D.
