rehma1bj Posted July 17, 2008 Share Posted July 17, 2008 Hello, I could really use some help because I have no idea what the problem is. I have a freeshbreeze 122 with solo 210. The fist time I flew the engine this year the engine seemed to run good until I tried to turn if off. The engine struggled to shut off when the kill switch was down and when it did shut off after 20 secs it chirped or screeched to a halt. Sounded like wear. I looked on the intake side of the piston had visible wear more so than on the exhaust side. I recently had the piston replaced. However after I got everything back together I ran the engine for 5 mins giving it no more than 3800 rpms. I killed the engine and it again struggled to stop and then chirped. I looked on the intake side again and I can see very slight visible wear. Any ideas what this might be? Why would it not stop and why does it screech to a halt? Thanks a million.

Farmer_Dave Posted July 17, 2008 Share Posted July 17, 2008 Have a look at the flywheel to see if both halves of the flywheel are tight together and all 3 screws are tight. I ask because I have one here which is falling apart and wont run. Other than that, how many cc's of 2 stroke oil are you mixing wih 5 or 10 litres of petrol? dave Quote Link to comment Share on other sites More sharing options...
rehma1bj Posted July 17, 2008 Author Share Posted July 17, 2008 Everything is tight. I mixed 1:25 and I used the 160 jet. Thanks for replying Quote Link to comment Share on other sites More sharing options...
dantheman Posted July 18, 2008 Share Posted July 18, 2008 Sounds like overrun, when the engine is running so hot (lean) that even without a spark the petrol is ignited by the heat in the combustion chamber and hence splutters on for a few seconds. Whip out your plug and check to see how it's running.... Quote Link to comment Share on other sites More sharing options...
rehma1bj Posted July 21, 2008 Author Share Posted July 21, 2008 I am away from my motor at the moment. But if the plug is white indicating it is running to hot then what should I do? Adjust the carb? Quote Link to comment Share on other sites More sharing options...

rehma1bj Posted July 21, 2008 Author Share Posted July 21, 2008 So I just need to turn the screw on the bing carberator or replace the jet? Quote Link to comment Share on other sites More sharing options...
Guest Posted July 21, 2008 Share Posted July 21, 2008 If the plugs central ceramic insulator is white then you are definitely running too lean and need to richen the mixture... however there is a way that the mixture can be too lean despite a correctly set carb. If the fuel line between the tank and the carb is not secured adequately the fuel can froth inside the line. Also any connections in the fuel line that are not properly secure can allow air in. Consequently instead of the carb mixing 'fuel' with air it will now be mixing 'fuel and air' with air (ie a correctly set up carb delivering a far too lean mixture). Make sure you have a perfectly sealed and secured fuel supply line before chasing the carb settings. Bing float type carbs are usually set and forget (unlike Walbro or Tillotson diaphragm carbs) so this could well be a supply issue. A float carb is not susceptible to the problems of minor air leaks in the supply lines however it is critical on a diaphragm carb. Quote Link to comment Share on other sites More sharing options...

rehma1bj Posted July 21, 2008 Author Share Posted July 21, 2008 After looking around I see the ground wire was not stripped before it was crimpped. It seems to stop ok now after running for a few minutes. And I have not heard the screeching halt I described earlier. So I guess problem is solved!? I'll have to run it more than 5 mins to see if the problem persists. Thanks everyone! Quote Link to comment Share on other sites More sharing options...
Guest Posted July 22, 2008 Share Posted July 22, 2008 So I guess problem is solved!? ...except you still have the lean condition you described earlier. That needs urgent attention. Quote Link to comment Share on other sites More sharing options...
rehma1bj Posted July 23, 2008 Author Share Posted July 23, 2008 Apprently it was never running lean. The repair guy said it didn't look like it was running hot. He said I was maybe hearing the belt. The spark plug is now a dark tan color. So unless the spark is lying I think its ok now. Thanks! Quote Link to comment Share on other sites More sharing options...
t_andrews Posted December 21, 2008 Share Posted December 21, 2008 If your ground wire was corroded or partially grounded, the screech could be attributed to an 'almost' backfire. That is, when the engine is dying slowly due to a partial spark/ partial ground, that last weak spark may occur somewhere other than TDC or fire the engine backwards, spinning your small pulley under the belt. Kinda like that 2 stroke bike that kicks you back. Glad you got it sorted. Quote Link to comment Share on other sites More sharing options...
