Hello,
The power head on this motor(model 35R78) was recently rebuilt and I can't get it to start. I've done the synch and link and everything I can do without the motor running . It has good spark and the fuel pump is working, there is fuel at the carb, compression is 120psi in both cylinders. I'm using a 25:1 mixture by the way(just for the break in period-if i ever get that far).
It seems to be flooding( the plugs are wet with fuel after attempting a start) and it also backfires after about 5 seconds of running the starter. Also, when I have the manual choke pulled and try to start the motor, the choke plate flutters(opens and closes) as the motor tries to start...thats not normal is it?
One other thing. I had old fuel(>1 year) in the tank which I replaced, I thought I was good to go, but the tank or line still had old fuel in it when I initially tried to start. The fuel looked like mud water(anyone ever see that before?). So I bought a new tank and line and flushed the whole system by removing the drain plug in the carb bowl, tilting the motor, and pumping the fuel bulb until the fuel draining out was "clean". I thought that would do it but nothing changed. I had also rebuilt the carb before trying to start the motor.
Anyone out there have an idea what might be going on with this thing?
thanks in advance,
Sam
