Re: GLV305 Compression question

As I'm sorting out my new boat, I did a dry compression check across all cylinders and sure enough, number 5 is sitting at 100 pounds with all the rest at 140, 150 and numbers 3 & 8 at 160..! So, I shoot some 30 weight oil into all the cylinder (three squirts each from and oil can then turn the mot...

Re: KLC Numerous Issues

What Trick414 did. Is really your only option at the present. The company that was rebuilding the gear pumps has closed and no one is doing them right now. I do wish someone would. The reason yours is leaking is the lip seal assembly has gone bad. Which is what the weep hole is for. If the bearing o...

It could be. The F series had a special upper tube that went between the manifold and the engine.

Re: oil line fitting size

You will need an original nut. Everything Chris Craft used was odd size and threads compared to anything available today. Once you have an extra nut. Any 1/4 compression ferrule and some 1/4 inch tubing will work. On the other end get the brass fittings from the hardware store that will let you adap...

Re: My boat mechanic working to put in a remanufactured 350 Chevy into barrelback

Its not a difficult swap. But its not a simple in and out either. There are some modifications that have to be done. I've done at least 20 of these conversions. Off the top of my head. It needs to be a marine engine. Not a car crate motor. You have to drill the nose of the crank for the oil passage ...

Hi Jim, The stampings on the block are the Hercules stamping which says its a long stroke marine engine. Flywheel is correct and the intake has to be correct since it has the KLC carb on it.

Re: wrong carburetor?

Since it will start on ether and you confirmed there is fuel in the float bowl. The carb is more then likely stopped up with old fuel and probably rust. Give it a go with trying to start it with the choke closed as the choke creates more suction in the carb so it pulls more fuel to go to the cylinde...

You have to set the timing running down the lake wide open. Advance the distributor until you hear the engine start pinging. Then back off until it goes away. Also will your running wide open adjust the high speed valve on the carb. If its running lean that can cause it to run hot. It also melts pis...

Re: Zero compression on cylinder 5

To have zero compression on one cylinder you have to have a big hole or gap somewhere. You ned to spin the engine over and make sure the valves are opening and closing and when they close they are fully seated. The ding you have will not give you complete compression lose. I had one come it one time...

Re: KLC Numerous Issues

100LL will work fine. Just keep an extra set of plugs with you as the lead can clog them up. Its a higher amount of leaded in it then the old car leaded gas.

Max RPM is 3600 for the KLC. But it varies due to weight load. You should at least get 3000 to 3200.

Since the gear pump will not prime by itself. Its worn out. Also since it is leaking past the shaft seal it worn out. The pump more then likely has an open shaft bearing bearing. Which will allow the water leaking past the shaft seal. As the leak gets worse all the water will not be able to leak out...

Since you still have points. Go to NAPA and get a 12 volt internal resister coil. Buy the top of the line.
