Default Need a few opinions

Ok guys...im really starting to think that something is wrong with my 86. the old girl runs great once you get her started....hard part starting. i thought it was my battery so i replaced it and same problem again....it turns over until it hits compression stroke and stops but once it picks fuel up it turns right over and fires off. im thinking either timing is a bit out on the points or my starter/generator is lagging again (it has been replaced one already got 2 on stand by). my battery is 360 cold cranking amps. so im open to any ideas what it is....i know the head gasket is blown again but will be replaced soon.

Check the timing, it can make a world of difference in starting.

I would start with all electrical connections, especially the ground(s) make sure they are good and clean and tight. Then see what happens.

I would start with the timing, simply because it is a definite, it's either right on, or it isn't. If the timing is good, then you can rule it out as a possible problem, and move on to something else.

Next, I would hook jumper cables from your running car/truck directly to the Starter/Generator, Pos to "A" terminal and Neg to ground. This is more or less another good or not good "test". If the engine wants to hesitate on the compression stroke, then the acr could be the problem. If the S/G seems slow or sluggish, it could be on it's way out. If it spins the engine over like crazy, then all is good and you can move on to something else without doubt.

There is a good possibility that wiring or grounds is your problem. However, the above mentioned things are fairly quick and easy to check, eliminating them as possible problems will enable you to move on to wiring and grounds with all confidence that this is where your real problem lies.

What made you decide, the S/G is faulty?

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.
