Well, after figuring out the PO had the engine overfilled about a pint. I dumped the oil and changed it making sure it was right at the full mark. The next cold start it didn't smoke near as much as it did.
I did notice after awhile when it was parked on concrete the right front wheel was off the floor about 1/4". While looking things over good found the tube frame the front casters are attached to was cracked all the way thru. I've found this Dixon is very mechanic friendly. Only had to remove the operator deck, front mower deck guide pin? and 6 bolts to remove the whole front end assy. Got it on the welding table, ground out the cracks w/ my die grinder, pulled it back into position and welded it up w/ the mig. The tube must have been tweaked a little 'cause I had to make a 1/8" shim for the king pin on that side. Anyway the weight seems to be even on both wheels now.
The engine change confirms my suspicion I've had for several yrs that they're putting unneeded HP on these riders. This Dixon came w/ a 14 HP engine and it was replaced w/ an 8 1/2 HP Honda and it has no problem even mowing tall heavy grass.
PS: How come the paragraphs disappear when I post??
