Going!! Thanks to Jamie, who stopped out and got our car moving , we now know that we need a new carb. Right now we're running on Jamie's borrowed carb, and need to find a replacement. And ad the electronic ignition!!! Anyone have a suggestion on replacing this Carter YF 1BBL? Does the Holley 2BBL 5200 work as a replacement for this? We looked at the tech article, but it never says anything about being able to actually close the hood, so we're not sure there was any resolution there....We'd like to still be able to close the hood without cutting any holes. Car is a 170 I6 The problem is with the kickdown lever and the way it attaches to the YF in our 69.5.........right now with Jamie's carb, we've got the "over the valve" bracket on, and had to redo the acc cable to the carb. It is not attached to the kickdown.......is there a kit they make to modify that type of linkage to the kickdown?
No problem, Dean. It most certainly was not a fuel pump problem. I have no idea what was up with that carb. It would fill all the way up to the point that gas would spill out the vent tube on the top. And some how, gas was running out the bottom of the carb around the throttle shaft. You could actually hear gas boiling inside the float bowl also? The car would sit there in the driveway and idle all day long, and rev up great. Drop it into gear, and it would immediately change it's tune, misfiring badly and trying to die. We adjusted the timing a little and I noticed the car was idling pretty high and you could smell that the car was running rich. Every time I tried to lean out the idle mixture, you hit the gas and would immediately be met with a deafening back fire out the carb. It was running all wrong. My thoughts were either a problem with the needle and seat, or maybe the float had a pinhole and was filling up with gas. Dean pulled the carb apart and we ruled out both of those problems. Everything inside the carb appears brand new. Swapped the other carb on, and the car immediately sounded better. Dean's son and I drove the car around the roads by their hose, climbed some pretty steep hills and had no problems, other then a moderately bad misfire which is definitely ignition related (the car still has points, which appear to be pretty old). Obviously, the 69.5's have that odd ball throttle linkage setup which doesn't work with later carbs, so we swapped on the '71+ throttle cable and bracket. Unfortunately, the bracket doesn't seem to fit correctly on the 170? And of course the kick down needs to be sorted out, as it was totally different to match that '69.5 throttle cable setup. I feel confident they are on the right path now though.
You guys did a great job... i ran my 250 w/o the kickdown ...just shifted to 2nd for passing... ...:Handshake...
It appears that might be what we have to do. We're looking at ordering up the duraspark II for the ignition, is this the right thing? I see it's about 75 bucks over at JC Whitney........... We're also wondering about putting that Holley 5200 2 BBL on there with the adapter. I sent a note over to that Stovebolt place, but they don't open until 4/7. Do you guys know if that will fit under the hood with a air filter on it? It looks to be the less expensive way to go as opposed to trying to replace the YF Carter........... We're trying to make sure we're getting the right stuff for this little 6..
I stopped back by today. Dean's son Garrett and I installed Duraspark II ignition and I brought another throttle cable bracket that I KNOW is off a 200. The bracket still didn't fit right. So we made it fit right. Unfortunately, the Duraspark ignition still did not solve the miss fire/rough idle problem. I fear it may be a valve or lifter problem and not an ignition problem.. The car runs much better then the first time I drove it, but it still just dosen't have much power going up hills. Of course, I've never driven a properly running 170 before, so I don't really know what I should expect. But I know my 200 wouldn't have much problem going up hills that this thing struggles a lot with. I think a compression check needs to be done on all cylinders, but I didn't have the stuff with me to do it. I made a video of the car running, which I was going to post, but after watching it on my computer, it isn't really as clear on the video what it's doing as it is in real life. We also changed the sending unit, but the gasket tore in the process and leaks. I assume one from a Mustang would be the same? Something neat I noticed when we were working on it today, the VIN on his '69.5 ends in 167167. The VIN on my '69.5 ends in 167193, so the cars are only 26 units apart, both St. Thomas cars. I didn't check to see if they were built on the same day.
