some usb charger from no were at $5 induce noise in radio com , some dont ,,,,,

i have a turn coordinator to do the same noise when transmit ,,,

scrap , over 500 f do not rebuilt

copper washer missing on the tester part to cylinder spark hole ,air leak just a little 5 to 10 psi lost

yes sir 10/10

Ps larger orifice , make more air escape, more sound, easy to hear for old men like me , 70 Michel

just to point for Tomas 1142 what could be the reason for is change in test ,Some engine(0-360) are test .060 and give reading 70/80 ,you change next year for instrument .040 and have a drop 65/80 if you no about , it ok . Test serve to find air escape , identify the leak ,intake valve ,exhaust valve """"by muffler , ring by air in oil pan , , source of leaks .. and boroscope to finish . Many AP use .060 on 5 inch piston and more , but you right about 1998 Lycoming bulletin , Michel

ok E2M and E2MA .040 orifice piston under 5 inch diam tester no E2M-100 orifice .060 for piston 5 inch and more like 0-320 0-360 Michel

look to me ,,,,, the are 2 size orifice for tester one for 5 inch diam . piston and over big ,,,,, and a smaller one for under 5 inch( smaller hole ) look to me your test was made whit tester for small piston like 0-200 ect 0-360 need big hole orifice tester , small one lower your test les air volume , if you look at the tester number you will find orifice number , sorry for my English. Michel

what is your price ,, $150 ok for me 418-392-3113 Michel

i thing it just start , like just not close completed , like hear little puff from idle exhaust , missing a beat , The final result will be like you said , and some time blow the head off , but could be water , but must have some in the filter , or air bubble ,

oup thanks

i will go for stuck valve , if my plane do that , just in case , Michel

thank you for help. Michel

last question, where are those servo so many door thank Michel
