'89 yamaha 115etxf compression test ????

[flounderman]

I was doing a comp. test, did cyl's 1,2 & 3, all were 100 #. Now the wierd thing cyl 4 was 102# but the starter would disengage after 3 or 4 revolutions, did it twice, the others would stay engaged untill I released the key. Any ideas? thanks Jerry
