Sorry-I couldn't comment on each pic directly--If you look closely at the very bottom of the first pic--at the corner of the foot plate, there is a secondary foot throttle--pushing it down-also brings the throttle lever rearward (towards driver) so the tractor is backwards from the "Book"?
I'm cranking her with a 650 cranking amp Marine battery. it spins it like a '63 plymouth. When I release the compression release, its apparent that compression is present because cranking slows considerably. After much trying it "seems" to try to fire because this cranking momentarily quickens--as if engine and starter are both working--for just a second or 2, thats all.***
I had 2 sessions today about 45 minutes this AM and about an hour this afternoon--the above repeats. I bled the fitting at the injectors twice this PM and in order to reach #2 cylinder, I pull the intake tube and white smoke-even flame is present in the intake.
Air in the injectors themselves? Darn thing almost acts flooded. The air cleaner may be dirty-haven't replaced it, but I've tried it with it removed-no difference.
I hung on to the starter switch and got it to go maybe 4 seconds--like its trying harder , then nothing.
My other issue is, Im really jumpy about cranking the starter-under compression, for more than about 15 seconds, for fear of frying the starter---------SO between cooling the starter, and re-charging the battery, its wearing me slick ...
