Hello everyone, here’s my story... I purchased a Scag Turf Tiger II paired with a Vanguard 35 7 months ago. It was their demo. I had nothing but issues with the Vanguard (to my surprise, I’ve read great things about Vanguards). The dealer could not figure out why it would run great when cold, then after running it, and letting it sit while string trimming, edging, blowing, upon start up it would puff out black smoke; but, then sputter until I choked it. Then it cleared up, ran fine again. Long story short, after 13 visits back to the dealership, and begging for my money back, while telling them I would purchase another one brand new, they decided they would swap motors and put the Vanguard 37 EFI on. Well, the motors were swapped. I now have the Vanguard 37 EFI. It starts great when cold; but, once it’s been warmed up and shut off, it’ll turn over about 10 times before starting. Anyone else with the Vanguard 37 EFI experience this? I took it back to the dealer; but, same results as always since the purchase. Nothing repaired.
