Do any of you have a good method of hooking up a choke/prime system on a ryoby 31 with the rear mounted carb once its inside a cowl? I've got an idea or two,but want to here how some of you are doing it.

put a carb with choke and use a servo or bellcrank with a wire for manule

I belive it was av8tor that posted this suggestion.If not,i dont remember the name.Go to a store and or gum machine and buy one of those little super balls.
Cut it in half and then epoxy it on a popsicle stick.
Then put it up the open space under engine and hold against the carb.The round part of the ball will fall into the intake of carb and youll feel it.Then just flip engine over 3-4 times and you should be set to go.
Buy doing it this way there is no air to leak in and youll get a lot of gas with just a few revoltions of motor.

either that or reuse the stock slider choke lever from a weedie or do something similar...
