Wondering what the rules are for 4 cycle versus 2 cycle body/tread width. I have it setup for 2cycle which measures 38 1/8 for my tread width but I'm going to convert to 4 cycle. It has a 36.5 inch body. So my question is does it need to be at least 38 1/2 tread width (which I've seen before I think) and do you have to run the 38 body work? I've looked in the Wka manual but can't seem to find it. Only thing I've seen is the 28 inch width rule. If anyone knows and can direct me to the manual reference I'd greatly appreciate it. I'm not wanting to buy new body work but I will if it comes down to it. Thank you in advance!
