Rory Posted May 11, 2016 Share Posted May 11, 2016 (edited) So i took apart some of my little TS4N for a good clean, and put it back together. Go to start it and fuel wont prime... not covering exhaust or physically blowing up tube. It wouldn't reach the carb. Spray loads of carb cleaner down there and manage to get it to prime as normal. It will only run for a couple of seconds then dies from lack of fuel - what I need to know is should the carb be flush with the body of the engine? I had it off, and when I put it back on it was very stiff to push back ... I pushed it down as hard as I could and even used grips to squeeze it .... but the O-ring at the top of the carb neck sits over the intake for the engine.... its not totally flush. Should I feel the O ring pop inside the intake as I push the carb home? I think I have in the past with other cars. Checked google images for pics to see if the O ring is visible but cant really tell. Edited May 11, 2016 by Rory Quote Link to comment Share on other sites More sharing options...
Ziggy122 Posted May 11, 2016 Share Posted May 11, 2016 Any pics of how your currently setup? As for the situation ur in, it would suggest its that youve got an excessive lean caused by the air leak Also when refitting - did you slacken the pinch bolt on it?

Ziggy Sent from my GT-I8190N using Tapatalk Yeah Im thinking it might be a carb air leak, thats the only thing that I took off. Yip slackened bolt , pushed down on carb and tightened bolt again. I never felt a little pop as the O ring went into the collar of the engine though , I think I might have on previous cars? This will be the 3rd time taking this engine out since I cleaned it the other day lol. Quote Link to comment Share on other sites More sharing options...

When installing something like a carb. with O rings then a bit of lube will be helpful.....never try to press rubber stuff into metal dry.....personally I always use RTV on anything...but you could always use some silicone grease...or spittle...WD40.....virtually anything rather than dry... Oh and many carb. necks are clamped in place by collets....ensure they are removed before trying to forcefully add/remove. Quote Link to comment Share on other sites More sharing options...
