10* caster, 0* toe-out. Engine is in stock location, approx. 17 " from front axle. I weigh 185lbs.

Tires:
Front = Trac-Gard 13-5.00-6 @12p.s.i  (both)           

Rear =                13-6.5-6   @15p.s.i  L    18p.s.i  R





And by the way that 17" is measured from front axle to point at which crank goes through hole in engine plate...

First thing I would do is lower left rear air pressure to get more stagger that will help it turn quite a bit. I would run 5lbs left rear. When I run a huffy I litterally had to add some weight to the left front it was simply too light with my big but on it.

I used a lead weight from old race car weights, bolted it to the frame right behind front corner of chassis. I could move seat any farther forward. I could move motor, battery everything I could mount to the front was. Been several years I think all it took was 20lbs. It made all the difference in the world.
Regardless thouogh I still looked like a ape riding a golf ball.. LOL

George, everything went well. I made adjustments to the air pressure and front end. Added 14lbs. of lead by melting a bunch of wheel weights and pouring into a form. When it cooled I bolted it to my E.C. front end. Runs really well. Thanks

So, after all of my adjustments, it does corner better. But now the one thing I noticed is that it pulls left down the straight-away. The more caster I give it, the more it does it. I'm not at 10* caster,  I'm at about 7 or so. Is that normal?

When my mower is like I like it I don't turn left, I hold right down the straight and let it turn into the corners!

Well- I would go a little more rectangular like 1 x 2. The length will be determined based on the finished dimension you want for the overall width with the wheels and tires on. Mine is around 18", so once i got the spindles and wheels/tires on, I'm closer to 36-38". I bought mine from EC. all ready to go-and love it.

Drop left front or raise right front or do both one spacer. Too much cross will make her push.
