Very nice dozer, to say the least!! Your issue with the motor may be not enough air flow over the motor to keep cool. Electric may be the best way to go. With your machining abilities, it should be no problem to make a drive system for the dozer. Ripper looks OK to me. Just needs to be pulled thru the dirt a few times and nobody will know its not yellow.

The Honda engine has a built-in fan that should keep engine cool. Have been thinking to add extra fan to get more air in-out of engine room.
Can't so much about engine (either), but if muffler don't let exhaust out easy I guess engine will have to fight harder to get mowing. Will test with new exhaust pipe.
Yes, yes, know wrong color on ripper but a soon model is up running good, all paint will be gone

Hi Dan Merry Christmas to you. Only a suggestion but you could try some computer fans under the hood to cool it and help remove exhaust gases. This is a very nice dozer and Big hope you get the kinks worked out so you can really enjoy using it. Ed

Yes Ed, have had same idea using such fan being powered from rc battery (have a large one and radio has voltage warning). Still think it's the homemade muffler causing the problem. A friend of mine installed a electric device that starts fan automatic when engine gets to a preset temperature.
