Pierce can rebuild anything that you can throw at them. It just might cost you a bit. If you need rebuild they are the people to talk to. They basically built me a carb for 800.00 and threw in the rebuild on two more. | ||

>>I have narrowed it down to cyl 4,6, and 10<< where is the raw gas coming from in those 3 cylinders? | ||

? LOL! You lost me....You really need to open a shop out here. I have narrowed it down to cyl 4,6, and 10. Bill, the carbs on my car are from a typo 211 engine. Will Pierce...or anyone for that matter be able to get parts to rebuild them? | ||

Sometimes the problems can be solved with the carbs still on the engine by partial disassembly and cleaning, readjusting the floats etc. you need to isolate what the problem/s are (ie: which circuits) before knowing how to solve them. For example: if the needles & sea ts are old & leaking causing chamber spillover the fix is just a matter of new seats. If the problem is incorrect float height a simple reset is all needed, etc. Point is without knowing "why" the certian throats are dumping raw gas it's not possible to know what the fix is. You can run some tests to help isolate the problems with the AC off, FP on, engine not running. Just pressure up the carbs and see what they do. There should be no evidence of raw gas dripping or pouring into the throats. You can also check the Acc. Pumps Circuits this way by looking at all the injection nozzles & Acc. pump quantities per barrel. | ||

Eye Cumberia! It's running on all 12 but the plugs foul fast. Carb rebuilt needed? | ||

Seems strange that it was running okay for a couple of months, this would eliminate jetting and possibly float levels - I would check the syncronising of the carbs, also check the accelerator pump jets for weeping fuel. Is the engine firing on all cylinders, a wet spark would result in high HC levels? | ||

JRV, There is gas in a couple of the throats. Also some of the linkages seem to get hung up. I think it might be more prudent to have them rebuilt. What's wierd is that it was running fine for a couple of months. M | ||

Matt, Color Tunes will tell the mixture even off of idle in the same way they show idle mixture. Off idle rich could be float levels set to high, flooding, wrong jetting, chokes stuck on, Acc Pump Circuits Check Balls stuck, etc. With AC off look into the throats for signs of raw gas. HTH's | ||

Hey Todd, Long story but I owe you a trip back down to SD. Maybe the 18th? JRV and Bill, You know the history of the engine not being a standard 250 GT PF. It idle's fine but runs very rich. I am sure the HC/CO are off the charts. JRV, I printed it out. It will take a few days to get it sorted out. I'll keep you posted. Thanks | ||

>>Is there a trick to sync 6 carbs? << Go to you know where {  } and follow the Daytona Carb Adjusting procedure in the permanent Tech Archives. If it's outside plug you'll need a little mirror. | ||

My brain is starting to work now. Check and make sure that all your carbs are 36 or 42 DCL's. I think thats what should be on the car anyway. My car ran fine at sea level, but when I got it home it was so rich that I thought it was going to kill me. Thats when I found the lone 42 DCL-6 hidden at the middle of the carbs. It was a bear finding a replacement, and I had to have it sleaved to match the others. Does your car idle Ok? | ||

Yes, there is a trick alright. Send them to Pierce Manifold first. Then expect some serious time with your car. Six is going to be way harder than three, and three took me a long time! Good luck. | ||

My car is running rich but I cannot tell which side so I am going to resynch the whole lot. Is there a trick to sync 6 carbs? I have done the 4 on the 308 but the 250 looks like it's more involved. I have a case (really...a case) of the colortune plugs. Any advice?.....Bill?.....JRV?... |
