Hard Starting

[ctltmp]

Hi guys. It's been a while. Priorities change...........

On my 52 cub, darn thing is hard to start. This is my work tractor, have no intentions of looking good, just everything working good. I needed the sickle bar mower and it came attached to a tractor.......

I went over it good when I brought it home last year. Full tune up, points, plugs condenser. They had a 12v battery in it with a 12v coil. I switched it back to 6v (it's the original distributor). Runs good once it fires off, but after it's been running an hour ago on a 90 degree day it shouldn't have to turn over more that a couple times to start. Any ideas??

Thanks in advance!

Timing slightly off or points need dressed/replaced. I like to idle mine down for a couple of minutes before shut off after working hard.

I'll check the timing tonight and take a look at the points as well.

Could be alot of things but definitely it should hardly need anything to start up once warm like that.

I started using NAPA parts for the ignition. IH200 capacitor and CS1600 points both say NAPA ECHLIN on box.

I was having a lot of problems with the IH points and the points from stieners and no names parts from others. The points came with a coating and I had the spring for the points break on two different tractors within a few months.

Also I use a multi-weight oil (15-45) in my tractors. I think that helps with starting when cold.

Like others said I would also check the timing.

Guys I'm using napa parts as well. I checked the points, they are probably within .003 of spec. Pulled plugs 1 and 3 are carbon fouling. 2 and 4 look good.

Cleaned and gapped plugs, dressed points, set timing (slightly off),checked wires (new). Still starts hard.

Maybe that's why the previous owner had a 12v battery in it to spin it over faster??

Probably old news to you , but I had fits with both Cubs till better grounding was arrived at.
I am a fan of the braided ground cable.
To a bolt on the transmission cover (cleaned up well first) on the 53 , and to an angle piece welded on the floorpan of the 48.

No starts and sluggish starts were kicking my butt.

I also cleaned the contact point of the starters where they touch the tractor frame. The frame hole edge in particular. Starters "rims" where they touch the frame when reinstalled too.

Stud on one starter was eroded till the voltage wasn't breaching the gap consistently anymore.

Guess I forgot how long it took to sort tough starting out on the 48. (!) But it was a learning experience.
The 53 wanted a new kill switch. It got it.

ever adjust the valves ? do a compression check ?

Ignition switch might not be allowing enough power to the coil, when ot is cranking. Run a jumper wiire from the battery to the coil, and see if it starts better.
