I just realized this is an 11 month old thread. They will easily to that and not give you any trouble but they will put more stress on your tractor if you spin them fast. I had a build pretty close to this on an Ariens and it was over clocked at 4000+ rpm
This is an engine that will reliably embarass every other stock machine on your block and now one will understand why it runs so good HA HA I like the Tillotson TF carb because its fully adjustable. I like the cast Champion generator valve train with Honda valves and exhaust retainers and caps on both valves for stability and ease of adjustment.
I like the 18cc head off the 5.5 Honda on that combination even though the valves are small ( you want torque not screaming top end here anyways ) I like the 636 predator piston in that block but with a HONDA OEM rod and 54mm cranks. I like the 70mm over bore blocks, but in a standard clone casting. I will tell you its best to build an engine out of parts. You would have to show us some photos of the engine to make some calls on what you need.Īsk 3 people and you will get 3 different answers about whats better a rebuild or swap. The other predator the 212 wedge has slightly different mounting brackets for the tank and this might match the parts on your MTD. If you have a standard clone all the parts will transfer but the carb and you will need to modify the 636 carb for a primer line ( not a big deal ). Predator 636 hemi ( last three digits of the SKU number on the box ) is a standard clone on the outside but with a bigger bore and longer stroke for a 212 displacement. You have the opportunity here to build an improved engine with better parts than the OEM and tighter tolerances for better performance, longer life and your own piece of mind in the future
I would suggest a roller kit for it as the easiest way to get up and running.īut if your willing to listen and ask the right questions I can line up up with some very specific places to buy individual parts and give you very specific information for assembly. Since its a used engine and you are going to rebuild it make a point of finding out exactly what you have and come back to this thread.
