Yep, its not hard at all to work on engines. I'm self taught and can do alot of procedures. Just go slow and read ALOT.
as am i,....sort of. i am in the procedure of self learning. it seems stupid at first, but forums help ALOT. when i first got my snowmobile i thought i knew everything about it, but then i realized i didn't know how to take the carb off haha. but now after much forum talk and starring at things for hours i can easily do a top end rebuild and other things.
also, the taking off the outer easy bolts first is a good idea. for example: take the bolts holding the carb off first. then take a god look at the carb and get to know how it works, and then just go form there. also diagrams online are helpful.
(knowing how things work is very useful and valuable to know when disassembling-assembling things)
