Spudders in higher RPM's or when you simply get into it

I have a Buick 225. and I have been having problems with getting into the throttle. when it reaches higher RPM range (I have no gauge in it so I am not sure what range) It likes to sputter or cut off like. I keep on looking at the ignition area. I have replaced the coil did not make a difference. I replaced the condensor (more because it just died and I was getting no spark) and it ran AWSOME for a day, then went right back to it. I was thinking maybe the points. I have fairly new plugs and wires. The cap and rotor looks good also. I was thinking maybe the points. I cleaned them up yesterday but it did not make a difference. Does anyone know if I am even looking into the right area or am I way off? thanks in advance.

 

If you can't get it to run at higher rpm you might want to look into the fuel filter and make sure nothing is plugged, it may simply be running out of fuel.

 

I agree, I have seen several that will run fine at lower RPM's and start cuttin out at higher RPM's because of the fuel filter. I would check it out before you go any further.

 

I just put that fuel filter on last year, but come to think of it, it also was on when it sat for the winter, so maybe it is clogged because of bad gas. Also come to think of it, when I first got it It needed a new fuel pump and AutoZone could not find the correct one, and I think the one I ended up putting in was from a 231 maybe. not sure.

 

The main problem is because of too much trash in the tank in the cases where it has been the filter for me. Even with a new filter, I have had to take it off and blow it out on several occasions until I could drain and clean my tank. It is just something you might consider trying first cause it is pretty simple to check.

 

mine had the issue that would run great around town etc but put your foot in it and it would want to die....... Fuel filter was the problem was starving for fuel

 

Take the fuel line from the tank off the pump. You should get a good flow of fuel. If not, change the filter. If it still doesn't flow, the pickup in the tank is plugged. With the gas cap off, blow air back up through the line. If that's not your problem it could be that a piece of junk has plugged up a passage in the carb somewhere, or the points could be bad. If you haven't changed the points, they're probably due. My girlfriends 1950 Dodge p/u did the same thing. The spring on the points was weak and they would "float" at high engine RPM and it would break up. Changed them and no more problem.

 

Well I guess that is the plan for the weekend then... Now I have to find a parts store that actually carry the points...

 

Should be available at any auto parts store.
I can get them at NAPA, Autozone, Advance, O'riellys and any mom/pop shop around here when I walk in.
Make sure you tell them if you have a Prestolite distributor or a Delco with the window to adjust the points.

 

What about the Carubretor?

I had the same problem with my 225, but it was because the carburetor float was slightly out of adjustment, as well as some sediment buildup in the bowl that had made it past the fuel filter.

After a little cleaning and a minor adjustment, she's been purring like aaaa...well like and 225 I guess

Make sure the ballast resister is good and not bypassed. This will definitly cause it. Ask me how I know.

 

I cleaned up the carb, and it did not change. Now the balister resistor I asume that is the device that kinda looks like a sphere attached to the distributer, then a vacume hose to the carb?

 

The ballast resisitor is the little ceramic piece mounted on the firewall.
The thing attached to the side of the distributor with a vacuum hose is the vacuum advance module to advance the timing as the engine climbs in rpm.

 

The vacuum advance actually retards the timing as vacuum drops (engine load increases), this helps prevent detonation. The mechanical advance advances the timing as RPM's increase.

 

how do you test the ballistor resistor? Well the fuel filter tested ok, also tested for blockage in the line, also ok. now the points, well i bought points from summit, the part # is right, but i can not see how it would fit, it is bigger then the one in it now it is a accel. so i bought another one from the zone looks the same size but it is flipped. why cant i find the right set

 

one other thing I noticed, if you are looking at the front of the engine, on the right valve cover the rubber line (vacume line maybe) just cut off, but on the other valve cover it also has a line but it goes to the rear of the carb. should the other one also go thier?

 

No! It goes to a point on the air cleaner.
If you're getting parts from advance, autozone or something similar, find a mom and pop shop that still uses books and knows what an engine looks like, that will help with the parts problem.

 

Ok now I just need to find that mom and pop store.. Wish I had the funds to get out of the old points and into a electric Distributer

 

If the distributor is in good shape the points will be fine. I run a Mallory dual point distributor, have for about 8 years now. The points have been in there for about 9000 miles, untouched. If you can find a Dleoc pointed distributor drop in a pertronixs ignitor. I just hate the large diameter of the HEI unit and the problems they create in certain circumstances.
