oh? what happened, I thought you were the master walbro tuner and I didn't know what I was doing. Now you finally realize that the walbro 603/668 can't keep up with a moderately modded motor? Just returning the flame job you did on me. Try a WJ series.

I believe the WYK has the largest venturi. Call Robert at ADA racing on Monday, he is pretty knowledgable about the Walboros.

The Walbro HDA series are used on most Zenoah engines between 50-100cc. For example, the Zenoah G62 airplane engine uses the HDA-48.
