BSE 5.5 from Moto Skeeter 550s

#1
Hello again all,

So I've got two Moto Skeeter 550s. Until recently, both ran like a charm, then one won't start any longer.

Compression testing shows 100 psi for the 'running' skeeter and only 60 for the other.

So I guess that tells the tale....curious though, what kind of compression ratings should I be finding on a 1972 vintage 5.5hp BSE....? I'm thinking 100 wouldnt be all that bad? and 60 is certainly not a good thing...(autopsy still to be completed on this one)...what kind of ratings would one expect on a 'fresh' motor?

thoughts/input?

much appreciated

(does this mean I'll have to change my name from '2 skeeters' to '1 skeeter and a large paperweight'??? LOL :doah:

Not sure on what they should be testing from factory but I've been told between 115-130 is good for a 2 stroke in general. Each motor is different though.

thanks for the info grumpyed, now my only dilema is....does anyone have the compression data on these things? I have been able to find no data on them....?:confused:
