130 suddenly running poorly

Postby lightninbug » Sun Nov 17, 2019 1:35 pm

My 130 has suddenly begun running poorly.

Symptoms:

1. Difficulty cranking. It sputters and backfires, twice it blew the rain cap off the stack. (I've drained the battery twice since Friday.) It will finally crank and seem to run smoothly until I put it under load.
2. It won't run under load. I can operate the touch control with it sitting still, and it will move in 1st, 2nd, and R (I haven't tried 3rd or 4th), but I can't operate the touch control while it's moving. When I try to lower the cultivators, it immediately chokes out; it doesn't seem to matter how much throttle I use.

Any suggestions from the collective brain trust about where to start with this will be appreciated. Since it was running fine three weeks ago when I turned three sections of garden with the two-bottom blow and was running well two weeks ago when I used the bog harrow on one section, I can't help but think something has broken, but I can't imagine what.

Thank you in advance for any suggestions.

Chris

Sounds like an ignition issue. Coil give out?

Suddenly running poorly usually indicates an ignition related problem or second guess fuel related. First thought coil failure.

Before purchasing any parts, heading towards a complete engine tune up, no cost tests/procedures first.

First ignition timing, then compression tests. These tests should provide a good indication of the problem area and engine condition.
I have an excuse. CRS.

+1 on what Eugene said, and after that while you have a plug out checking compression you might try testing the plug and see what color the fire is on it. (NOTE Be sure its grounded and where you can see the plug gap) If the fire is blue, all is well with coil, if orange then coil or plugs are bad (may just be fouled and can clean plugs up) I'd also do that while you remove each plug. If compression, timing, gap (both plug and points) are good then if fire is orange it may be condensor or coil. If fire is good then next thing to check is gas. If old replace fuel.

Thanks! Hopefully I can get into it this weekend to see what's going on.

I had the exact same thing happen to my 130 this past summer and it was negligence on my part . It started and ran fine ( or so I thought ) in the beginning of summer and then one day it was hard to start , ran rough and lacked power . End result was green corrosion under the distributor cap , partially fouled plugs,worn points etc. With new ignition parts it starts and runs great . I am still amazed that it ran at all looking at the heavily corroded and worn parts . This tractor stays outside all year under a tarp at a seasonal camp . I had just put off the maintenance way,way too long ( luckily I have changed the oil filter, fluids annually ) ...........

Thanks, Bob.

Because of weather and work, it's still in the barn waiting for me. I'll be sure to check those issues when I get to it some warmer day after the holidays.

Lightninbug if you have time can you post a picture of the timing marks and pointer? I am having trouble finding them on my 130.
When you only have 9 horsepower you need to know the names of all of the ponies!
