    Sorry, pics are in reverse order.

    Nice clear pics on how to measure squish.

    On those carb screws, most will cut the ears so you have full adjustment. Just a sharp utility knife will do the job.

    M2theB are those pieces of solder, held in place with some grease in order to measure the "squish"?

    I gather that is the way to measure the gap between the top of the piston and the cylinder head?

    That's exactly what it is. A very soft solder, it's hard to find lead wire, that came off the spool at 062. The measures at the wrist pin are most important. The high was 0275 and low 0265. I wanted to see above 0200.

    Thx :thumbs:

    Edit.. the grease reminds me of Polyrex EM, I see a lot of it through my job.

    .062" solder...or lead wire...is it softer than normal solder? I ask because even with .035" electrical solder I always roll over tdc 10 times or so until I can't feel the solder any longer. If I twist 2 pcs together I can't get it to roll over if squish is below .025"ish .

    This is soft stuff and its solder. Probably mostly lead though.
    It is an electrical solder that I got from an industrial setting, so it's probably not at HD. Infact, if looked there and did pick up some electrical and it wouldn't work for me.

    I was told by one of my builders that 4 pieces is too much. I did it the same way till he mentioned it and had me use just 2. I also sent him the pieces after I did the check and his high end calipers measured a bit different than my cheaper one.

    I'll let it set over night and if I have time when I get home from work tomorrow we'll gas her up and see how it goes

    All the pematex products I looked at had a caution not recommended in the presence of gasoline or something similar. So I settled on this stuff, high temp, use with auto fluids, etc.
    Checked the compression first thing this afternoon and was cautiously disappointed. It was 125 to 130 psi. I felt better when I saw the decomp valve decomping. I pulled it out tried again. I got just short of 160, so felt better. I also think there's something squirrelly with my pressure gauge.

    Fueled it and got it to pop after 5 pulls. Set fast idle and pulled it to life.
    Runs nice! Stops and starts right up again.
    I made few cuts on a round. It was ok. I'm in shorts and working on a round, so I wasn't really in a position to give it a good test. The chain needs some attention too.
    I do like how it runs.

    I did see a seized 359 today being offered. I had to take a run at it.

    160 sounds pretty good

    Permatex grey should be ok I reckon.

    I'm declaring this one viable.

    I woke up this morning around 02:00 wondering why I didn't like the cut. I thought I did an ok job on this beater chain, but maybe not. And wondered if the bar was too wide for the kerf, because the initial cut was ok but when I got more than bar deep into the cut, that's where it was a dog.
    So tonight I pulled it apart and found I got this beater with an 050 gauge chain on an 058 bar. So I swapped the chain with a sharp 058 and made a bunch of cuts.
    Rakers may be too low, but this thing didn't care and threw out chips like I was noodling something on a 16" round.

    I like it!

    I like it. I've always liked when inspiration/insight pops in at odd times.

    Just goes to show, your brain was still working on the project while you were pre-occupied with other things.
