1985 Columbia cuts out
I have had this cart since about 1990. Always ran great until about a year ago. I have gone through the fuel system numerous times and have decided it must be ignition. It goes a few feet and then cuts out, immediately restarts and goes a few more feet and cuts out again. I say it "stutters". I have played with timing a little bit but that hasn't helped, sometimes better and sometimes worse but never good.

Re: 1985 Columbia cuts out
Could be a few things but you are probably spot on with an ignition issue. I would think the most likely issue is the coil going bad which happens. The key switch could be buggy as well.

Re: 1985 Columbia cuts out
Does it take a special coil or will any universal, 12 volt, coil work. I tried a Bosch coil from a car that I think is still good, didn't make any difference! I did install new points and condenser. I have a factory repair manual and plan to try to get a more accurate point adjustment, and timing setting, using that TO THE LETTER.

Re: 1985 Columbia cuts out
Long term, it needs a "continuous duty" solenoid but one from a car should work temporarily. Obviously, it's more than your solenoid.
You need to see if your spark is consistent ie, not starting and stopping. The best way to check is with a visual spark indicator. Check compression as well, it should be over 90 but something in the 80s will probably run. Lastly, you could have a "not enough gas" issue in that your fuel delivery is weak. Your motor gets good gas and runs but then it leans out and stutters. Once the fuel is caught up it will run good again then stutter again when it leans. |

Re: 1985 Columbia cuts out
THANKS for all of your help & ideas. Today is finish the J. D. Tractors. Tomorrow I will start through your suggestions. I think one thing might be to install an electric fuel pump. I have changed the 3 connector Mikuni pump a couple of times but it always seems to run about the same. It does do a little better when the choke is pulled about half, but richening the mixture makes no difference. That is why I tried to concentrate on the carburetor. Perhaps the crankcase vacuum/pressure is to weak to work the pump. THANKS AGAIN, Don

Re: 1985 Columbia cuts out
Yeah, those crank seals may need replaced. I have 2 85s. Replacing them isn't too tough.

Re: 1985 Columbia cuts out
Hey Lochlin, I need more help. My '85 Harley/Columbia engine is now all apart. My Son-in-law is a "get-her-done" guy. Came at about 6:30. Took it out of the cart and at 9:30 disassembled and a parts needed list. I had checked compression, 110 psi. Decided that the main shaft bearings are bad and the post that operates the points is wobbling all over the place. List we made is main shaft bearings and seals, and complete gasket set. Any suggestions? Should all '85 parts fit or are there several different variations, do I need a bunch of engine numbers to get the right pieces? Can you suggest a good place to start looking? Any other input would be greatly appreciated. I would like to give you my phone # but I guess I should do that in a Private Message, I don't know how to do that! THANKS, Don

Re: 1985 Columbia cuts out
85s are a bit of a red-haired step child as they are the last in the era when Columbia was converting away from legacy HD framework. The service / parts manuals are rare but, after a few years of interacting with other carts owners, I was able to luck into both. Parts were largely shared with other machines, to include 80s era EZGo carts, so parts are still surprisingly easy to come by.
The service manual is attached in two parts. Critically for your venture the parts list is also attached. This manual covers both 84s and 85s. Although most parts are the same for these years (all engine parts are the same) there are some differences so pay attention to specific year call outs. All of the OEM parts numbers are listed. There is a business dedicated to old carts: vintagegolfcartparts.com. Regardless of whether or not you order anything from them their website is an awesome resource as they list all OEM part numbers, have photos of most items, and will inform if a certain part is no longer available. I did the bearings and such on my 4 wheel '85 a couple of years ago. You'll have no issues with finding parts. To be honest, I procured the parts / gaskets and took everything (along with the service manual) to a local machine shop and they did all of the work for $70. That's something you might want to consider. For about $100 ($30 for parts and $70 labor) I got a basically new motor, ready for install. Also, the electronic ignition module that was used on later Columbias, will easily fit into your cart and eliminate the points altogether. There is a sticky about it here: http://www.buggiesgonewild.com/gas-c...formation.html The modules aren't cheap but nothing I have done with these carts made as positive of a difference as converting from points to electronic. I'll check your PM a bit later today. Although I monkey with carts as a hobby I am actually a suit and tie guy at work and Monday morning are busy. |

Re: 1985 Columbia cuts out
GREAT! Thanks again. Just ordered $150.00 from Vintage. Hope all is correct. Should run like a new one. Thanks also for the manual downloads. I have an original shop manual (maybe a reprint). The parts manual is most helpful. Son-in-law loves to rebuild engines and transmissions. Hope the parts arrive by Friday, Saturday he will have it running again?
