We have left the 1/4x32 full shielded spark plug lead out of our price list.I have to hand build these and do not have much time to make them. I still have the parts and build them when I can find the time. I thought XuLaing at RCEXL was going to build these caps but he is ill and has not been around for a couple of months. Does anyone no what he is ill from,they will not tell me what the nature of his illness is.
If you use just the little silicone boot it will create a lot of RFI If the ignition has a stranded copper core it will be much worse. RCEXL has tried to find a good 5MM resistor wire but I guess they don't make this in China.There 10MM-CM6 ignitions with resistor wire has gave them a lot of problems. Now he is using solid core copper with a 5K resistor added in the metal cap. Even using a good resistor wire The ignition is very noise with a none resistor spark plug. The NGK CM-6 -10MM is non resistor but they have a full shielded cap for these.
There is probably room on the OS-160 cylinder head to drill and tap for the 10 MM spark plug.This is what we do on the ST 2300.Much tougher and lower priced spark plug. We use two spark plug gaskets on this Mod. I will look into having a Walbro carb adapter built for OS 160.
Do not use much less them 10% oil with a bushing type rod.Do not ask me how I no . The ST 2300 ran for about 10 min when by mistake I put in 40 to one mix in the tank.
I still do not think these conversions are worth the cost and agrevation ,when there are so many good little gas burners available. I no they do not make the power of the OS
but what ever.Terry(TKG) has a Zenoah G-20 on a mini pipe that turns 8800 on a 16x8 APC. Sounds like a glo engine. Maybe this is not good. I do not own a tach,so I do not have all of these RPM problems.
