Hello, I have a 1975 dt 400, its got a huge dead spot in the throttle, and it kicks back when I kick it. Just got the bike had a broken woodruff key. Starts and idles just hesitates when you open it up.I cleaned the carb already.I also bought a dial indicator and it does seem like its in time, although I might not of been using it right. 2.9 mm btdc. Any suggestions? Thanks

my suggestion is keep the throttle closed when kickstarting her

Standard kick process.

Couple of slow pushes on the kicker till you feel it come up against the engine comp.

Then take the kicker back to the top an give a strong 'kick' through that compression. That should have it go ok.

Ok ill give that a try, when I get my kick starter back. It broke last time i kicked it.
