Hi everyone, so i have a Fly100evo paramotor which i have trouble diagnosing. What i have done so far: I have changed the cylinder and piston after they got stuck running too lean ( may have been damaged before as well since i bought it used). I have also done a carb rebuild (new gaskets and membrane) since it seemed to build up alot of air in the fuel line coming to the carb. The Problems i am having: -I can fly fine for about 20 mins then it starts behaving irregular in the RPM of the motor. loosing power to the point where i cant even climb anymore. -Now recently it have also started smoking a bit. - I used to have problem with it stalling when bending forward with it on my back until i did the carb rebuild. will changing the carb and reed valve to new parts help? I'm quite handy guy but combustion engines ain't my field so if anyone got tips i would greatly appreciate, I read this below which seems to fit my problems. but being stubborn i have hard accepting the not reparable part. The pilot bends over and the engine stalls. This is NOT a repairable problem! It is caused by the puddling of fuel and oil in the crankcase. Bending over will allow the flywheel to slop the puddle (usually with a higher concentration of oil) into the combustion chamber. The engine may either smoke a lot for a moment or stall source: http://www.southwestairsports.com/ppgtechinfo/top80/hrservicenotes/performanceissues/performance_issues.htm

I have a Polini Thor 2oo Evo engine. With a Bing carburettor fitted. The engine has always had a little problem, engine runs fine from tick over all the way up to 4900 rpm and from 6100 and higher. However the engine runs rough between these two power settings. If I make the smallest throttle movement the revs will run rough and if I keep making small increases in power I get to a point where the power band kick in and it jumps up to 6000 rpm and runs sweet as a nut. unfortunately for me at 6100rpm The aircraft wants to climb and I can’t maintain a level flight and 4900 the aircraft will descend. Any suggestions would be much appreciated

Hi All, I read this site everyday with Firefox but today I get this: An error occurred during a connection to www.paramotorclub.org. The OCSP server suggests trying again later. Error code: SEC_ERROR_OCSP_TRY_SERVER_LATER Chrome is fine. I think this happened a month or so ago. Not sure what changed. Anyone else getting this? Thanks Danny
