Andy G. Posted February 11, 2018 Share Posted February 11, 2018 As far as I remember, it just unscrews. But I think you have to unscrew the red bit from the crankcase as I'm sure the metal hexagonal head with the C02 feed pipe is fixed to the red bit and doesn't come off. Be very wary of damaging that tiny and fragile pipe!! Quote Link to comment Share on other sites More sharing options...
dave windymiller Posted February 12, 2018 Share Posted February 12, 2018 If i recall, you twist the whole cylinder to alter the rpm (raises or lowers the valve in the head in relation to the piston). Keep twisting it anticlock and it should come off but dont let the pipe twist. This method of throttle control wasnt great as the pipe suffers as you twist it when mounted in a model!

Martyn K Posted February 13, 2018 Share Posted February 13, 2018 I thought the Telco adjusted its running speed by altering an offset nut on the front of the crankshaft which raised or lowered the crankshaft thus restricting the amount of CO2 passing into the cylinder. I have a brand new one here I have just looked at. Mine has a metal cylinder head Quote Link to comment Share on other sites More sharing options...
Buz Cederlof Posted December 3, 2018 Share Posted December 3, 2018 Hi onetenor, I realize your post is from earlier inthe year, but I run a Facebook page named "CO2 Model Flying" and we discuss working on these motors, and you can post a question. Heres the link **LINK** As well, I sell parts for many different type CO2 motors, you can view the current catalog at this link: **LINK** We're just a group of guys trying to figger out this co2 motor stuff together, feel fre to ask anything.
