(Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..

This old boy has been coastal so lots of rust. But when I turn the key, nothing. Green neutral light works, head/tail lights work. Was running fine when I parked it for a few months.. no issues with starter. This did happen once before (last year).. not sure what overcame it.. maybe playing around with gear shifter.. but not sure if that was what did it. But doesn't seem to do anything now when I play around with it while hitting the start button.
I did take apart the handlebar mounted start button housing and looked it over. Couldn't figure anything out there, but looked the same as when I had the problem last year. Put my probes on various wires there but didn't learn anything.. not sure how it is wired.
So this first image there is a connector with 2 wires coming from forward (the male part of connector) - one blue and one blue w/ red stripe. The blue continues down to a post near where the gear shifter enters the housing. (Second image). I was wondering about that.. I opened up the connector and the 2 wires (coming from forward) show continuity when I put my probes on 'em. Thought that was weird, but maybe supposed to be like that? I turned on the key and tested for voltage but didn't find any.
I'm just unaware of how to test for anything. Would be interesting to put 12 volts to the starter, but not sure about doing that or how. The wires going in are kind of hard to get to. I suppose I could take out the starter.. but wanted to ask if there is something easier to check first.
Thanks for looking!

Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!!
Drove about 100 yards, ran about half throttle wouldn't idle. Put on somenew parts, jug/piston and rings, carb and valve seals.
'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
Thanks for any thoughts.
