Hi,

When you take out the gasket under the cylinder to raise the compression, here is the stuff to use to seal it. It is called Yamahabond case sealer from Yamaha. A tube runs around $6.00. We use it on our engines in our ultralights as well and this stuff works great. I just used it on a Homey hop up I'm doing and as always, it sealed perfectly.

Now my question: On the carbs with a plunger bubble for priming, can you just run a "Y" fitting in your line from the gas tank, or do you need to run a separate line??

Thanks,
