93 Suzuki 140 h.p. compression

[kenh1010]

I have a 93 Suzuki 140 that runs well. When going at very slow speed I noticed seems to shake a bit<br />more than I think it should,so I did a compression test. The results were as follows.<br />#1-149#<br />#2-135#<br />#3-146#<br />#4-136#<br />As you could see, im very close to the minimum 15#<br />difference between cylinders. Does anyone know the normal compression for this engine?<br />It runs great at higher speeds but could this be the reason for the little (kick) at idle speed?<br />It idles well under no load (not in gear).<br />Thanks

kenh,<br /><br />I think you are OK. I would do a decarb. and check again. <br /><br />If you are not sure of the decarb. procedure, use "decarb." as your search word on this forum.<br /><br />The Suzuki 140 I owned also had real sensitive carbs. It would plug the jets.
