MEP806b no start MPU

[319cssb]

I got this 806b . Was supposed to have been running a while ago. Not it isn’t firing , just turning over. I bypassed the fuel shut off and the gen starts. Shows 43.1hz instead of 60hz .
Removed the MPU and after a long struggle got it out. It had a bunch of rust flakes stuck to it. Due to the lack of space the wires got a bit twisted and in not sure if they have been damaged . So I ordered a new sensor, installed it and it shows only .5vac, whilst being maybe a 1/4 turn away from the flywheel. It was a MSP675 , I have bought from Amazon. Looks like it’s a Chinese knock off. Anyhow the gen set still doesnt
Is there a good known supplier for these sensors?

I heard a dream one time of a burr on the threads for a MPU, wouldnt let MPU adjust down to the flywheel,

verify the depth of MPU
