davidreckitt Posted May 26, 2016 Share Posted May 26, 2016 Hello I own a brand new Simonini Mini Evo 2. It should have come with a 2 blade helix prop. For some reason Helix let the dealer down and so it was arranged to have a hyfly 3 blade prop sent to me instead. So..I cannot start the motor with the prop on. The motor starts just fine (for a second before I shut it down) without a prop. I put the prop on and the thing just turns over and over. So I can conclude that all is working in terms of the motor itself. It has a brand new YTZ 7S Yuasa 130CCA battery. The carb is clean. So one major question - can the prop type/design have such a major effect on the ability of the motor to start? It just seems the starter cannot get quite enough turnover speed to kick off. The earth from the starter motor did overheat at one point during my attempts to recharge another battery. Would that be a cause? Thanks for any help at all Frustrated David Quote Link to comment Share on other sites More sharing options...

admin (Simon W) Posted May 27, 2016 Share Posted May 27, 2016 Also worth saying that the starting motor on these engines are not great (they don't last very long) if used regularly. Although it may be a pain in the bum, it's maybe a good idea to buy a new one. At the end of the day, you either need one now, or will need one in the future. So if when you fit it there is no change you have a spare SW 1 Quote Link to comment Share on other sites More sharing options...

Neilzy Posted May 27, 2016 Share Posted May 27, 2016 I had a Simo with three blade prop and the only way it would start would be primed and then turn over it would fire a couple of time then I would add the smallest amount of throttle and it would start. I sometimes would take the spark plug out and prime and turn the engine over replace the plug and that would help start if it had been stored for any length of time Quote Link to comment Share on other sites More sharing options...

SW Prop should not make any noticeable difference between 2 or 3 blade Quote Link to comment Share on other sites More sharing options...
