broadmoor 738 questions

Recommended Posts

noob that needs help... first, i'm glad i found you all, i thought i was weird with my love of my 738. in fact i love it so much that when i broke a piston ring i ended up honing the original engine .050, added a .030 pison with .020 rings, and ported the intake. it is by far the best mower i have ever used. anyways, my tires are pretty bad, the fronts are 5.3x4.5-6 which i can't find anywhere. what size tire can i fit on that rim? the rear is common size so i won't have any problem with them. my other question is i have no first gear, is that a difficult repair? i'm a mechanic by trade, but this gearbox looks quite a bit different than anything i'm used to. the only reason i want it is because i'm about to invest in a snow blower for it and am afraid that the other gears might move too fast if there is a lot of snow. thanks in advance.

Welcome to the forum. The transmission problem can be fixed but lots of the internals for that one will probably be no longer available. Not sure how you have the right ring end gap when using .020 rings in a .050 cylinder?

About any of the narrow profile tires for a 6" rim should work. I have had good luck with both of these vendors.
