Glad to hear that you have it running well, a reliable idle at 3500rpm is great for any .15 engine. :)

Older engines had a smaller bore in the carb, and would draw fuel fine without the extra pressure from the muffler. The addition of muffler pressure then enabled a larger bore in the carb to be used...

It sounds like you do not have enough pressure feed to the tank from the muffler. Which muffler do you have?

Yes, i liked it very much. The radial mount is a big improvement over the stock tank, that simply vibrated too much. The Turbo plug gave a large boost in power too, but the throttling was better on...

The power of the .030 engine can be increased over the stock version, for sure.
My best version will do about 21700 rpm on the Cox 4.5x2 prop (and 10% nitro), but even the hottest Turbo plugs from...

Yes, I think they used regular M2.5 threads on both the FSR and FP (I can check if needed). I have replaced several of them with regular M2.5 hex screws. The head screws are usually pretty worn on...

Glow plugs are either for 1.5V or 2V (but 2V is not common these days). There is no plug designed for 1.2V. When a 1.2V NiMh or NiCd battery is fully charged the voltage will be higher than 1.2V,...

Regarding the carb screws, they use some sort of locktite on them I think. A little heat from a hand held torch is usually enough, plus the right size of JIS screw driver.
