I’ve run a fused wire (10 amp) off the fuse box. It starts well and does seem to open up completely after warm up but I find it idles at a higher rpm, similar to the earlier post. If I continue to have problems or get annoyed with the higher idle, I may install a manual system like Chris has chosen to do. I just wanted to give the electric choke a try since it’s already there. In the final analysis, the choke is only needed at the very start and even then, usually on warm summer days.
