My brother recently acquired a cub cadet 149. It is in reasonable condition, has a mower deck and snowthrower.
The problem is it won't start. The past owner used it regularly (he passed away without anyone else knowing the secret to getting it to run). Here's what I know:
It has spark, pretty good spark actually.
It gets gas (plug gets wet after trying to start).
The starter (starter/generator combo) seems weak--it has trouble turning it through the compression stroke. It seems to have a bit of torque (I can't stop it by holding a wrench against it when the belt is off). We're having the starter rebuilt.
I put a new plug in. It fires on almost every rotation, but it blows back through the carb each time (one time creating a nice little fire . I'm a little suspicious that the timing is off and it is firing far enough before TDC that it is pushing the piston 'backwards'/blowing back out the intake valve, but I don't see how to adjust that (and I'm not sure it is the problem anyway).
I've tried a little starter fluid and various options with the choke and throttle. Any suggestions would be greatly appreciated.
