1650 gas

dirtpusher · Oct 5, 2014

haven't been on here in a long time so I'm hoping some of you folks can still give me some advice. I have a 1650 gas that I have owned for about a year and a half. It only gets used to gather up round bales so it rarely runs for more than a hour at a time. All summer it has run well but after an hour it would quit and not restart for about 10 minutes and then would be fine for another hour. The coil would get extremely hot so I replaced it last week. It started and ran great for about 15 minutes then began to miss and run like crap. After trying a second coil and doing a general tune up it will start and run good for 2 minutes the run like crap and eventually quit. i'm pretty well confused here. I know these tractors pretty well my 1550, 550, and 2 770 gas burners all run like tops. This tractor is my only one with the holley distributor and I've been told they are junk. Is this true? Where else should I look? I was looking into an electronic ignition before but now i'm not sure if maybe I should get a Mallory distributor first. I apologize for the long post.

I went to electronic ignition in the Mallory on my 1550. The points kept wearing down and closing up on that one. It acted just like you describe when they'd start to close. It would act just like it was starving for gas. The electronic ignition solved all my problems with that one.

I also have the electronic in my 1550 whick also has the Mallory. My concern is that I want to know if the holley is worth keeping. Do I put an electronic ignition in my holley or do I put a Mallory on it then do the electronic ignition?

I don't know. My others are all Delco. I wasn't happy with that Mallory at all when it was stock. There's a little screen in the side that lets moisture in. I can't imagine that a Holley could be any worse than that piece of junk.

I've got a Pertronix electronic ignition in the Holley on my 1650. Works great. It was installed when I bought the tractor, so I don't know how bad the original points acted. However, the only time I've had symptoms similar to what you described, it was fuel related (clogged fuel line). I'd still suggest getting rid of those points, you'll sure appreciate it in the winter.

First, confirm which system is at fault - ignition or fuel.

It certainly appears to be ignition, but may not be. 'Is there a spark when it stops?' is one giveaway.

The distributor may be worn, leading to reduced contact gaps, the condenser could be leaking. Continually burned/pitted points are an indication. Multi-cylinder engines are more problematical due to the decreased dwell angle as number of sparks required per revolution rises.

The ballast resistor, if fitted could be short circuit.

It is usually down to a simple fault. Finding it is the main problem for most that don't really understand the system which has been around since the early 20th century (the system replaced magnetoes). Electronic replacements are clearly the modern replacement, but the old system has been successfully used for decades.

I know Grandpa's 1600 (now my 1600) was always finiky and eating ignition parts. Wasn't any better after I rebuilt the tractor, so after about 25 hours (and having to replace the points, condensor, cap, rotor, etc....) I went to EI and it's been running great ever since. Had to replace the cap last year, but it was a few years old at that point. The symptoms sure sound similar to what you're having.

1600 has a Delco distributor on it.

Thanks for the replies guys. One thing I forgot to mention was that the second coil I tried was a high energy coil. Could that have harmed the breaker points?
