This snowmobile was given to me along with an 88 400. The 88 is running good now. The 86 is all together after a top end rebuild and it has no compression on either cylinder. The engine has not fired once yet. What would cause no compression in both cylinders? It has maybe 5psi in either side. Would the crank seals be so bad that it would have this little compression?
When it was given to me, I was told that a screw had been taken out of the oil pump of the 86 to put in the running 1988 400 but I cannot see what screw is missing on the 86. Would this cause the loss in compression? Thanks!
