I have a few problems with the HT20 that you guys might be able to help me solve.
1. mower deck decided to lose RPM's while mowing. PTO and Deck Belts look good - but they are 15 years or older. Can I adjust the tension on either.. as I believe one or the other is slipping.
2. The tractor is trying to kill me with Carbon monoxide poisoning. If it wasn't so much fun to drive - it wouldn't be worth it lol. I don't see or hear any exhaust leaks - and the tractor doesn't smoke under load. Just a little on start up, sudden throttling down, or shut off - and really it's not that bad when it does. Tractor does have an electric fuel pump and the carb is not set to the 2 turns and 1-1/4 turn that I had read elsewhere. I can't remember where it's adjusted exactly, but cranked on it until I could get the tractor to idle and throttle properly.
3. It has a ghost (I'd like to think it's grandpa messing with me). It'll randomly start running forward. It'll be idling.. not going anywhere.. may set for a minute.. or 20 minutes and then suddenly it kicks into forward movement (albeit at a slooooow speed). No clue why.
This tractor is 100% stock - original muffler, etc. All covers are installed on the motor, as is the top panel.
Anyways - I appreciate any suggestions you guys might have.
