Mebob2 8 #1 Posted March 5, 2022 Hi guys, I started working on a tiny tiger I purchased back in April,2020. It was used very little if any but would not run. Took carb off and followed tutorials off this site, I knew nothing about ohlsson and rice engines,1974. Played with if for a few weeks on and off in the evenings. Main issue was getting the little check valve thingy, it was stuck and I didn’t want to drill it out (as suggested)if I could help it. Finally it seemed to function properly. Then everything sat in the corner of my work bench disassembled until 2 weeks ago. Finished full carb cleaning and reassembly as shown on this site but used original gaskets and diaphragm. I used 24-1 with 30w as per manufacturer. Used an auxiliary fuel bottle above engine as I wasn’t sure if carb would work well enough to suck fuel out of tank or work at all. Second pull it fired right up. Quite smoky. Jet was out about 1 1/8. I let it almost run out of fuel. Changed fuel mix to 32-1 using STIHL 2 stroke oil mix, backed jet off to 1/2 turn out. Started it again, runs like a top. Just a slight hint of smoke, running smooth and steady. My next question would be, what is a good No load rpm? My tiny tack shows a steady 5500 rpm, is this too high? Share this post Link to post Share on other sites
Wallfish 698 #2 Posted March 5, 2022 Glad you got her going! 6300 rpm is typical for these little engines Share this post Link to post Share on other sites
Mebob2 8 #3 Posted March 5, 2022 I appreciate the reply, I did see 6300 mentioned but seen some other opinions as well. I’ll use 6300 as a baseline. It starts great, 1 pull choke , 1 pull half choke and it’s running. I misspoke in initial post, jet is out 1/2 turn. I’m getting a bit of oil coming out exhaust, comes out we’re chrome manifold fits into aluminum exhaust box. It’s much better then it was with 1 1/4 turns out on jet. Is there anything I can adjust differently to help this? Or is there another issue? Is there an approximate engine running temp that I could use as a reference? I appreciate your help thanks Share this post Link to post Share on other sites
Wallfish 698 #4 Posted March 5, 2022 The other thing you can try is adjusting the carb when the generator is under load. But it seems like you got Share this post Link to post Share on other sites

Enjoyed following your work in progress and troubleshooting with members 😊 Are you having trouble running an O&R ? If so, best to start a new thread of your own and let us know the background of the engine and if it's on a tool like a TT Share this post Link to post Share on other sites
