Hey guys, new to the site but not R/C i found these GO engines to be a great value after doing some homework, I managed to find one on ebay it is a gen 5.5, it's in great shape but when it comes time to rebuild can I just purchase the TiNi crank and throw it in there? (I do port my engines so I dont know if the TiNi coating would be what I want if there are no other changes to the crank)

Also wondering if any novarossi carbs would fit this engine, I am fond of them, or shall i look for a GXR series carb?

thanks in advance fellas this thread is a wealth of information but it's 600+ pages long lol
