I am at a loss. I doubt it is lines since it tracks straight.
I can be moving at 30 mph and stand on it, and it doesn't pull either way.
I have to believe it is the booster.
but since this is lack of power, it is harder to "prove" without that gauge.
And thanks for the web pages. I did find a few online. I was just hoping some national parts chain might carry them so I don't have to wait till next week to figure this out.
but it looks like an online order is at hand. I found one for about that same price with several adapters, so I might go that route.
