The first tiem she didn't start I let her sit for 2 days then she started right up and did every time since. I only started her every few days. So, after filling the coolant with 50/50 Presetone for a fill up she won't start but here's an interesting thing: If you let her sit for a bit, she actually almost turns over...or perhps she turns once but doesn;t keep going. it almost seem slike she is starving for gas. I am wondering if there is too much air in the line because there was no coolant in her for so long?? I know I am reaching here, but any advice would be great!
