Dellorto install Started yesterday, stripped plastic and removed stock Mikuni and reeds  My original throttle cable wound up being too short after putting a 90* fitting on top of carb to clear the seat bucket After a few hours of digging through my cable stash... I found a longer cable It pays to hoard parts   Got the corb and cage on, hooked up and adjusted cables for throttle and remote choke  I figured I'd have to cut a hole for the filter to fit...but it went on without modifying plastic  It was a tight squeeze  Remote choke location  Now to put the plastic back on it, and tomorrow weather permitting I can fine tune  |

Well last week while experimenting with jets on my dello, I got it running pretty good After running it pretty hard for a while........... it shut down and engine would rotate,but not start After it cooled, it fired right up I'm thinking soft sieze? Made a leak tester    Pumped it up to 6lbs, and within 4 minutes... it was flat zero I think the permatek stuff I sealed the cases with gave out , Well see Did a compression test & read 125 (kinda low ?) Looks like I'll be putting it on the bench and trying to determine where the leak/s are I've got a gasket order coming soon In the meantime.... I'm gonna pull it apart and start over, when I find leak/s Hopefully the cyl and piston are salvageable |

Nice tester. I could not find fittings like the one for your intake. All I could find around here is threaded stuff.
You've probably already done it, but make sure your tester is sealed well. I had a heck of a time getting my exhaust sealed for some reason. I thought my cases were leaking like crazy at first.
125 is a little low. If your squish isn't tight that could be normal I suppose.
What you did sounds like a soft seize. I did that so many times when I first got T2. Don't worry just yet. It may not be that bad.

I tested the tester lol after I made it and it held for a half hour with no loss, so it oughta be good to use I used a little 3/8 in test plug inside the pvc cap to seal it to ensure the tester was good Like these but smaller ( these are 7/8" and 1" I got to seal exhaust)  My local Ace hardware has them in many different sizes The hardest part I had finding was a gauge that went to 30psi max, there were many available for 120psi, also had to buy a cheap blood pressure cuff at Walgreens and throw everything but the bulb and I kept the stethiscope for listening to parts  Total cost was about 30 bux I looked around for ready made leakdown testers and way too expensive for what they are Thanks to you and Robert's posts....... I got 1 on the cheap I performed the leak test while the engine was still in the scoot I'm going to take it out and remove all the cooling plastic so I can get a better idea where my leak/s are The low compression kinda worried me though I'll see what I'm dealing with after I get it apart I guess |

I looked back and you said it was set at 1.4mm of squish clearance. You probably aren't gonna get really high numbers with that much clearance. Not really sure what your kit should normally do though.

After putting it to the bubble test, I was relieved to find that the base, head and case were sealed good......... but when I swapped carbs and put new reeds in, it was leaking bad at the intake  I was pleased to find the rings free and no damage to the piston or cylinder   I have several gaskets and some other stuff on their way from Canada When I built it the first time, I just slapped it 2gether with minimal knowledge, it performed well but when it goes back together..... I plan on experimenting with some port matching and tightening up the squish for more compression It should go back together next week sometime I hate waiting for parts  |

Glad it was minor. Great excuse for you to do a little more tuning. ;D Just leaving that head gasket out should drop your squish clearance .4-.5mm.
