I have a Bolens model 100202. It ran great last year. It had a new plug, new points, new starter clutch, new diaphragm, the carb was acid dipped and a new primer cap. This year it won't start. I have new gas. It has spark but wont turn over. I put a little gas in the carb and it starts until that burns off. Does anyone have any thoughts? It is a older model snowblower. Thank you for your help.
