Post subject:  Valve adjustment question

I've got a 35 GDSD with about 200 hours on her. To my knowledge, the valves have never need adjusted. I'm trying go find out if the 35 vanguard had adjustable valves or do I need shims to adjust them? I've noticed that lately it's been a little harder to start my motor and a little bit of black smoke out of the exhaust when I do start it up. It usually gets worse once the motor is hot after running for a while.

Am I correct in thinking that a valve adjustment would help use issues?

Pull your valve covers off and set dem at 0.005 while at a 1/4" past top dead center.

Well, adjusted my valves this afternoon. Really easy job. But I did find a new problem while doing so. Went ahead and checked compression and I'm WAY low on each cylinder. 82 on one side, 86 on the other. I really could have done without this. Oh well, time to start looking for parts.

No, didn't open the throttle. Guess I'll have to check it again.

Without the throttle open the intake is basicly a closed valve cutting off your air supply. No air means your not going to get the air needed to displace / fill the cylinder, causing the piston to draw some what of a vaccum until it can compress what air that it had or what it could actually suck in.

Is that right BJG? :mrgreen:

Post subject:  Re: Valve adjustment question

either that or u set the valves to loose. But i dont think thats the case. They would have to be really loose.
