Status: offline 		Guys
My Z230 with Zenoah has a strange problem. It is about 4 months old the chopper that is and ran fine the first three. Now after it runs 4 to 6 minutes the engine gets hits like it's an ignition problem. The engine will start fine cold but after one of these episodes it can be a little hard to restart but does does. I am pretty shure it's ignition related but don't want to throw money at it yet. Have checked all the other possible causes and every thing looks ok. Anybody with any ides please respond would like to get the pucker facter out of this machine.

It really sounds like the carb diaphrams are weak. Did you try opening the high speed say, one turn, to see if it gets real rich? If you don't see a big change, then the carb needs rebuilding.

Full tank or anywhere down from there. It will start and run fine 4 to 6 minutes does not care where the fuel level is. Fuel tank is plumed so it has suction to carb, return to tank from carb, and vent to atmosphere from tank 3 lines. Thanks

Status: offline 		An engine needs four basic things to run. fuell, spark,air and compression. Something that happens only few min after starting the engine must not be (at first)an air problem. Check compression after and before, if equal then check the spark taking away the plug and grounding it to see if you still have or not. If all the three checks are ok then you should have a carb problem. Check the wide joint between the carb and the cylinder to see if it was bend or broken. Check also the carb temperature after these 5 min. to see if itīs hot a bit because if so you loosing some fuell are evaporated. (may be due to a bad temp isolation with the wide joint or due to an overheated engine.

OK , I wasn't sure who made the Z230. I have a G231 engine in my Bergan Intrepid.
