I just got this running . I put a new impeller in it.it is pumping a little water but not much.I think there was a rubber boot that the water pump tube slid into that if I remember correctly did not look right.I am going up to the shop to remove the foot.Do I need to blow compressed air in the tube on the motor to make sure its not stopped up.Fairly certain I have the water pump on correct.It is a 62 or 63 not 72
.

15036 best I can tell ITS A 62 or 63.i blowed air. through the water tube and air was coming out of the exhaust holes.Something did come out of the exhaust holes.I reinspected the pump assembly and found no problem .Then I tried to crank it and it would not crank.I checked spark with a tester that lights up and I'm getting spark.Tommorrow I will replace the plugs.I just cleaned the old ones and try it again .At least I did have it running for a little while so maybe there is hope for it
