Still working on this engine. Starts but won't run unless 1. Throttle is pumped
constantly or 2 wobble is pumped or 3 primer is pumped. Any of which will keep
engine running at 1500 +_.
I have taken the carberater and fuel pump off running engine with no effect. Also
cleaned points in both mags.
Any ideas?

I had a problem similar to this in a Yak 52. A Friends Yak the problem was
the fire valve was closed. Fire Valve fuel shut off valve, tried for about
an hour till a friend came over sat there pumping the primer keeping it ru
nning till it quit sat there and looked around and said is this lever suppo
sed to be off? problem solved turned the fuel ON.#1 throttle pump probably
after pressurizing the system, on a Yak the system primer-pump (wobble pump
) draws from the header tank by passing the fuel valve also why #2 the wobb
le pump works. #3 primer CYL also by passes the fuel valve. so go to the en
gine side of the fuel shutoff valve and see if you have fuel flow.
I believe in a Yak when you run out of fuel there is 2 gals in the header t
ank that can be accessed buy the primer pump as it draws fuel from the bott
om of the tank the header tank is there to supply fuel to the engine invert
ed and when upright that fuel is unavailable.
