i love the pull starts since i'm using two 46cc goped engines but they're heavy as hell. a single cylinder 46cc engine with the pullstart, ignition, clutch, and fan weighs 4.8 kg. a twin cylinder 100cc engine with ignition is only 2.8 kg. being a plank engine there's not much i can do but using onboard electric or external electric starting. i was hoping to kill two birds with one stone

Wow, that's a large engine.
I guess the simplest solution, if not the most elegant but one that will get you in the air sooner is to use a dedicated generator and the electric (onboard or external) starter.

Yours must be an interesting project.

May I ask what the 100cc motor is in or going in?? This is purely out of curiousity.

that's cool I am thinking about building a conventional helicopter that would utilize a Desert Aircraft 150.

what's your plan with regards to starting, cooling and the clutch?
