I need to borrow a tool. I would buy one, but they cost around $80 and I only need it for about 30 minutes. It is used to replace valve springs, particularly when the heads are still on the engine. It has a shaft that is just like the rocker arm shaft, with a long handled lever on the shaft that slides to the valve spring you need to compress. It comes with a spark plug insert for putting air pressure in the cylinder, to keep the valves shut while you are working on them.
The reason I need to replace my springs is because this engine sat around since 1988 with pressure on the springs, only being turned a few times during that period. I suspect that these springs have remembered some of the shape they were in, and that all of them are not operating the same. I suspect that this may be the reason that the engine stumbles so badly when advancing the throttle. For those of you who I have not told, Steve fixed the engine for me, and it is installed and has been "run in". I am now trying to fix an oil leak that I think I caused when swapping the oil screen plate for a side drain adapter that I got from Revmaster. Once that is done, I can get to some real Aero Carb tweaking and then on to flying. Oh, I am installing the O2 sensor, so expect that the tweaking will be much easier this time.
