Hey guys I'm new here if what I'm posting about is inappropriate please delete me.Im restoring a home made "cart" from the 1940s for a deceased freinds grand daughter.Its heavy..prob 200 pounds at least and has 15 inch diameter wheels.I have a 13 or 15 hp engine for it and I need to figure out gear ratios with a jack shaft.I have used online calculators and I ve got decent results but I'm good with the moh my concern is that it will have enough power to get moving and not toast the clutch...here's the ratios so far..clutch 10 teeth,jack input 20 teeth,jack out 20 and axle 50 teeth...that equates to a ratio of 5.00 and 10.22 mph.keep in mind this is for a 9 year old girl...it just needs to drive around and be safe.is 10 mph too slow?Is this ratio gutless from a dead start??...Any help will be greatly appreciated,I have zero experience with this but I'm stoked to get on the welder and learn!!!
