I have a 23 hp Vanguard GD longtail that I have had no problems with until recently. This summer I had to replace the starter solenoid and last week I had to have the start rebuilt. I put it back on and no cant get any fire. The motor turns over and I have gas, but nothing. I have run it several times this summer with no problem so this has me confused. My kill switch seems to be in working order. It's just seems to be not getting any fire. OK brain trust what say you?
