Rear tires with more traction

I remember my uncle who raised me picking up scrap mowers all the time. One of them was a 5HP B&S and manual transmission like you describe. That thing operated good until you hit any kind of minor incline.

He also picked up an 8HP snapper rear engine rider and that thing was like a little bulldog. It was too bad the deck was in pretty bad shape so he had it hauled for junk.

With your tire situation maybe an ATV tread type tire would work best for you.
 
As I understand the problem with ethanol , its not the engine as such , its all the other fuel related bits. Such as non ethanol compatible fuel delivery systems, "O" rings, diaphragms. etc

With no evidence to support my position, I think the use of ethanol, as a method of redusing dependence on fossil fuel, is a con job.
Ethanol is produced from crops. Crops are grown/harvested using diesel fuel, oil derived fertilisers and pesticides, (if rainfall insufficient irrigation required). Up to this point only sunlight has been cheap. The crops are transported by diesel truck to a ethanol plant, that then uses prodigious quantities of electricity to process, brew and refine the resulting ethanol into a fuel - where is the savings to the environment??

Then there is the efficiency of ethanol as fuel, - lower than both petrol & diesel. So you will use more of it to deliver the same performance - where is the savings to the environment??

:devilish:
I live very close to an ethanol "still" and the tremendous amount of steam coming off the distilling towers is staggering! Visualising the sheer amount of natural gas burned to turn that much water into steam is impossible. This isn't a good use of a finite resource. I also can't imagine the carbon footprint of burning all that natural gas! All this waste to produce a worse fuel than plain gasoline or diesel. What a scam!
