ORIGINAL: SAVAGEBANE
ok cool, thats what i was thinking, but i just wanted another opinion. I cannot wait to install it onto the the mt2. I was looking at the backplate of the motor because i was going to seal it there, but it appears that it is a ''onepiece'' with the crankcase??? is this correct. I am still planning on sealing the carb body with permatex red rtv sealant.
Any pointers or suggestions/experiences from those who run this motor? I have the 52t spur and 13t or 15t vented cb, which combo should work best with the stock geolander tires.
thanks for any input you have
Sealing the carb and/or backplate is quite unnecessary on a brand new engine; especially as well made of one as a current O.S. Don't get caught-up in all these "seal your engine" posts from the seal-obsessed people. It is completely unnecessary on this engine and you will just be un-seating the good seal(s) that was created with initial assembly.
I have the .18 CV-RX with slide carb (#11881) (ok I have a few of them) and it is a good engine except for the one-way bearing which likes to slip but hopefully you have several happy gallons to go before that. I run my MT2 with a 13T CB and 52T spur but I am not after all out top speed and it is pretty fast with that gearing and has the best bottom end acceleration. If you want more speed than you can get with your 13T or 15T CB just throw in a 49T spur. (that is what the now discontinued MT2 kits came with)
Here is some info from O.S. Engines web-site about air leaks. I highly recommend reading it in its entirety:
