Carburetor issue

[Kurt Adams]

Well, this is more to share info than to solve an issue.  That way if someone has the same problem it might come up on the search.

Since I can't ride yet, I had my friend take my berkshire up and down his driveway (1/2 mile long) a couple of times to see if he noticed anything strange with the bike.  First trip went good.  Second trip the bike started to surge slightly then loose power until it quit.  Then he tried to start it up and it would run as long as you did not put a load on it.  This then progressed to running as long as you didn't twist the throttle.  It would idle fine, just don't ask it to do anything else.  

Spark check = good.
fuel check = fresh premix and fuel was getting to the carb.
plug condition = wet.

After digging into the carb, I found the main jet had come out of the carb and was causing the issue.  Once I screwed it back in and tightened it, all was well again.  Guess it was only finger tight when I put it all back together.  [:I]

So, if you ever do a compelte rebuild and your bike goes south in a similar fashion - check the main jet!!
