Well I noticed it was making some kind of "cling" noise.. so I pulled the valve cover and cranked it over.. one of the pushrods was just kind of rattling around, and not pushing the bar thing that actuates the valve on the other side.
Made some adjustments, then with the valve cover still off, I reached down and kicked the starter, while using my other arm to hold the throttle open full.
She roared to life.. so I put the valve cover back on, hooked the starter pedal return spring back up, hopped in the cab, stomped on the starter and..
..rurr.... rurrr..... ruh.
darn battery is dead!!
I have the other 6V battery on the quick charge.. i'll try that one in a little while.. maybe i'll get the thing to move before the sun goes down.
