I have an O&R23FRV ign which would be a good runner except that it has a sideport shaft (ie no shaft port, so no way for fuel or air to get in except via the exhaust port).
Does anyone have a suitable spare (venturi UP timing) that they would swap for the sideport shaft? I don't want to try drilling a port.
Alternatively I also have a spare 19FRV UP shaft and housing available to swap. This fits in the 23 but of course the stroke and timing are wrong.
Serial no. of the engine is 457990
