I have checked the timing and shimming multiple times and everything is to spec, I have spark and new gas, and I just cleaned the pilot jet. Before cleaning the jet I could get it to turn over for about a half second before it would die out but only with the choke off and holding the hot start lever. After cleaning it I turned the gas and choke on and it started for about a second first kick then died now it is doing the exact same thing that it did before. Questions: 1. Do you think that I could have missed some particles when cleaning the jet and that is why it start for a second then possibly got clogged back up? 2. Possibly running to rich and is flooding it, hence the reason it will only turn over with hot start lever? If so, how do I adjust it? 3. Any other possible solutions that I am missing?
