LukeSandiefer Posted April 27, 2017 Report Share Posted April 27, 2017 I'm doing a squish test today, and was wondering what gauge solder to use. And from what I remembered, you bend the solder to an "L" shape, stick it down the spark plug hole to the side of the cylinders, not to the exhaust and intake ports. Is all this info right?

You can check squish from exhaust or intake. Through the spark plug hole and in line with the wrist pin. Something soft, like 50/50 and something that is thicker than your squish will be.

Canadianshee Posted April 27, 2017 Report Share Posted April 27, 2017 I just did my the other week after a rebuild. I used several different sizes for comparison. Sizes used were 0.062, 0.125 and 0.84. Sent from my LG-H831 using Tapatalk Quote Link to comment Share on other sites More sharing options...
LukeSandiefer Posted April 28, 2017 Author Report Share Posted April 28, 2017 So I got the numbers, and I got a consistent 0.051-0.053 this is good correct? Quote Link to comment Share on other sites More sharing options...
LukeSandiefer Posted April 28, 2017 Author Report Share Posted April 28, 2017 And also, if I have 21cc domes and 0.052 squish, mixing 110 octane with 93 pump is preferred? Sorry, i'm new to all the technical stuff lol. Elevation is +500ft Quote Link to comment Share on other sites More sharing options...
LukeSandiefer Posted April 28, 2017 Author Report Share Posted April 28, 2017 is this a stock stroke and bore engine? if so, you should be able to run just premo gas on 21cc. Yeah, stock cyl and stroke. Are those squish numbers good? Quote Link to comment Share on other sites More sharing options...
Canadianshee Posted April 28, 2017 Report Share Posted April 28, 2017 Yeah, stock cyl and stroke. Are those squish numbers good?I'm not an expert on squish there are a few guys on here that know this very well. Only thing I can say is depending on your build your smaller number should be near the cylinder wall your larger number should be towards the spark plug.

trickedcarbine Posted April 28, 2017 Report Share Posted April 28, 2017 Good to go. Quote Link to comment Share on other sites More sharing options...
LukeSandiefer Posted April 28, 2017 Author Report Share Posted April 28, 2017 Good to go. Fuck yeah, this is my first "engine build" and everything went so smooth. Compression is good for not even being started up yet, passed leak test, and squish is good. A lot of people doubt us teens lol. Thanks for the help everyone Quote Link to comment Share on other sites More sharing options...
