Since it's the wrong engine anyway, there's little point in going for a lot of accuracy in the paint. I'm pretty sure it's an acrylic enamel on there and when I dumped fuel all over everything-(I had to rebuild the carb before testing it) the paint didn't run. Messing with catalyzed paint in a school environment probably breaks some rules, and you might have someone looking at how many microns your respirator filters, evidence of "Respirator Fit Testing," stuff like that. (Unless you DIY without students) That is a new gov rod on it and I noted crappy throttle actuation with that bit of throttle cable I left on it, so that needs rigged- probably need to move the Gov rod down lower on the Gov arm holes. There's plenty to do without painting. Maybe save it 'till the last once you get everything buttoned up and working right. Green spring in clutch for example is a cool classroom project. LMK off line if you guys need a hand.
