Default RE: GMS .76 idol needle

Don't expect your new engine to run perfect until it is broken-in. Read this link:

Get yourself a gallon of fuel (with castor) and follow the instructions from that link. GMS engines require a good break-in period before you can expect to get them dialed in, and plan on using that whole gallon of fuel just for this purpose.
