Loss of power and stalling while Mowing

Postby Mr Ziffel » Sat Jun 03, 2017 10:21 am

I am trying to mow grass again . I am using a woods 59 on my 1950 Cub. I usually have no problems with the mower even in tall grass with the deck elevated enough. Recently AFTER the engine gets fairly warm I loose power and stall out when the pto is engaged . I put the tractor in neutral, disengage the PTO a)nd it fires up ad runs normally , until I mow 10 or 20 feet. I put in brand new plugs and it makes no difference (others were carbon fouled somewhat. I have never been sure about my Governor Is it supposed to kick in under load? and give more power?
I can put the cub in neutral and move the Carb.to Gov. rod and it revs up fine. It does nothing when I need power (ie. mowing )
P.S I can turn the spindles by hand and the deck does not bind at all

Coil, replace with a known good one. Next guess, condenser.
I have an excuse. CRS.

Thank you . Will get one to replace it asap. I will let you know what happens. I had an old motorcycle that would conk out when it got warm at traffic lights, but when you let it cool off a few minutes it would start again. I had to keep up my speed so the air could keep the engine and coil somewhat cool. The minute you stopped, the coil would get hot and conk out. As soon as the coil cooled she would go again. A new coil did the trick then. :thanx:

Hi,
The governor should keep the engine running at the speed it is set at the throttle lever, as long as the engine has enough power to run the mower, or whatever load that is put on it.
The external linkage has to be adjusted right so the governor will work right.

If the coil or condenser is bad, like Eugene said above, then the engine won't run right. :)

Re: Loss of power and stalling while Mowing

The good news is , i have a nice looking coil without the ugly external resistor. The tractor runs fine but it is still loosing power
and stalls out. It was tuned up last year so I decided to check my fuel condition. I removed the fuel line prior to the carb.
and drained a pint or so into a glass mason jar. I saw a few flakes floating around in the fuel . Using a clean magnetic pick up wand
I found a lot of fine metal particles stuck to the head of the tool. There was also some non magnetic junk floating around.\
It looks like the relining job done by the prior owner has failed somewhat. I have had her over 6 or 7 years now.
Its my fault for not putting a filter on the darn hose . Looks like the tank needs relining and the
carb cleaned out.

Any input on relining jobs that are permanent ?

Redkote and Por 15 are both good, but they probably won't bond to the old liner. I'd suggest the Model T tank filter that Bill Hudson did a "how to" on.

I tend to overkill on fuel filtration. I crud gets in the tank I don't want it in the carb. I'm moving to the following configuration for my Cubs:
In the tank, http://farmallcub.com/phpBB2/viewtopic.php?f=139&t=94154
The sediment bowl has the filter screen installed.
In the fuel line prior to the carb, http://farmallcub.com/phpBB2/viewtopic.php?f=139&t=38266
In the carb, the small inlet screen is installed.

Fuel flow has not been a problem for any Cub this filtration configuration has been installed.

I'm still not positive it's not the coil/condenser. Even new out of the box coils can be bad.

Thank you all for the good ideas. I was hoping to reline and get the tank clean inside. Has anyone been able to re-coat a tank after a previous
reline job. ? My brother took a tank off my Grandfathers old 8n and placed clean gravel in the tank and left the tank in the back of his pickup.
A couple hundred miles of country roads did the shaking . I dont want to beat up the cub tank doing that though.

I will try the fuel problem and if that doesnt solve things ,I will go back to the coil and condenser etc. Thank you for your reply.
The Napa coil I bought IS made in China. So.......... :roll:

Eureka! Yesterday I installed a new fuel strainer from TM along with Bill Hudsons Model T filter modification.
I was able to cut grass for over two and a half hours with no problems. What a great feeling that was.
I also said a prayer to the good lord above, and want to thank him above all else .
You guys have been very helpful. Thank you all for your input.
