So...I have a few questions
2. When I pull the two crank cases together I will obviously use the new gasket...but should I lightly apply some hylomar sealant or equivalent on both sides of the gasket as well? I’m thinking not but I’ve read plenty on here that says I should...
3. Should I omit the base gasket and measure squish, or should I install the base gasket and measure squish...or does it not matter?
2. I put a thin coat of Yamabond 4 on the surfaces of case and gasket before pulling them together.
3. Do both. Use gasket. Use grease to stick lengths of solder up to edges of 4 corners of piston. Using flywheel to turn crankshaft, turn piston past TDC and back and forth several times. Measure the thickness of the solder in the squish zone. Use a thin solder as close to squish size as possible - gives most accurate results. Now you can use the same solder lengths with the gasket deleted. If the results are too thick and too thin, you can use a very thin gasket such as aluminum coke/beer can to get closer to what you want.
