Default Cadet 149 engine

I rebuilt the engine in the 149, K341.

It runs ok for a while, then like the timing changes, it misses pop, sputters, but will run nearly ok when I throttle it down to an idle. In fact it runs so rough and shakes so I was afraid it might come apart.

I changed the condenser, made no difference. My small engine parts guy says the voltage on the points should be 8.4 to 8.5 volts. Mine is 12 volts, same as the battery. I put a resister in line with the voltage lead and fried the resistor.

I am thinking the points are getting so hot they fluttering and the points arm may be flexing under the high voltage. Would this be right to assume??

Any ideas guys? I need some help. Is the 8.4 to 8.5 volts the correct voltage for the points?

Thanks
Dave

This statement is WRONG.

You should have upwards 13.7VDC at the Ignition Coil.

IF....you have the correct Kohler Ignition coil, then no resistor is needed.

Default Ignition

I bought the Kohler coil, suppose to be the correct one, I don't remember what it cost exactly, but I thought at the time it was pricey.

If I did not have the correct coil, what is the purpose of the resisitor other than drop the voltage?

Default Coil

I pulled this 12volt coil off this morning, it has NO part number on it nor the mounting strap. I don't think that would be normal for a Kohler part, but thats what I paid for. Looks to me like a generic coil....It is 6 inches long from very top to bottom. That looks longer than what is in the picture you sent me.

BUT, when I shook it there is liquid in it. I don't remember ever hearing that in a coil before. Has it got water in it or did it come that way. The Cadet has been covered anytime it has been outside without exception.

My Kohler coils have no identifying marks either but they did come in Kohler boxes lol.. One has died after6 months of use so my next one may be the Bosch. Have no idea for your problem but thought I confirm your coil might not say it was a Kohler.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
