Some time back I bought a 35-S from Tom Lay but haven't been able to run it until recently. Finally got the right fuel though (GMA 10/29) and have been breaking it in as per instructions. Had a mis-step at first as it wouldn't run through a complete tank of fuel without loading up and quitting. However, I replaced the glow plug (OS Max A-3) with an RC long style plug and solved that problem. It runs smooth and starts with 1 flip, even for me.
