putting the motor back together
I think your best bet for this first engine build is to find an engine building friend that lives near you. Someone on this site with experience must live in close proximity to you. There is no substitue for experience, even if you can & do read & follow the instructions in an engine assembly manual. Having someone experienced present to guide, mentor, & assist (not do the work for you - that's not helping you at all and not what I'm suggesting) will make a tremendous difference in the ease of assembly, the knowledge & comfort that it was done right and that you can fire it off without worries, and hopefully the confidence & the ability to do it on your own the next time. I'd say that it's time to start networking.
