    When I do pickle an engine (which is rare) I completely fill the inside of the engine with oil and drain it out. Install into a ziploc Baggie and away I go. I use a concoction of mineral ATF, and...

    Doubt it. 5-10% nitro 20% castor made fresh in my basement. I also make and use 5% nitro 25% castor in my bushed engines, 30% nitro 8% oil in cars, and 80/20 FAI fuel from time to time. See...

    Cutting out on throttle transition usually indicates a lean low speed setting. If there is a midrange adjustment then it's a piece of cake. If not, then you have to battle with having the...

    Hydraulic locking doesn't usually blow the whole cylinder off. Usually as has been said, the conrod and/or piston suffer the most damage. A 2-stroke is more likely to run a little bit and hydraulic...

    I stand by the point of this being a manufacturing defect of some sort. Nobody is going to tell me a 21cc piston and rod could hydraulic lock so hard it blows the cylinder apart without any other...

    That is some pretty serious carnage for just a hydraulic lock. Looks to me like it had probably had a stress crack or other anomaly that fatigued the metal and perhaps under the right...

    So yesterday my friend and I made the new heads for low nitro glow fuel for my Fox 1.20 twin. The factory heads (center 2) are setup for 25% nitro fuel. New heads are aimed at 5-10% nitro. ...

    That's odd it's gotten goopy on you. I've never had the sensor safe RTV silicon get mushy or goopy. I've used it on many engines too. Maybe I got lucky?

    You guys must have missed the part where the OP said there was not enough tank pressure from his homemade muffler. Plugging a tube cured the trouble?

    For its day, the Combat Special .35 is quite impressive. .87bhp is crazy high for a .35 of the era, eh?

    I'd use the black stuff. It's sensor safe and intended for oil pans. I use this or the copper colored stuff. Never had the stuff burn up. The blue stuff that doesn't harden is a joke IMO. ...

    I'll add a question; do these little .15's prefer to rev like many Enyas? What props are ideal? I'm much more accustomed to larger engines .29+ so an 8x6 is he smallest prop I've spun though I...

    With the head off, the piston will get stuck at TDC. It starts to get snug about 1/8" from the top of the cylinder. Yes I know it's an iron piston engine, but it has a pinch! My SS30bb had...

    Being able to open the needle valve 4 turns and it doesn't go rich tells me it's not getting enough fuel. On most carbs, 4 turns out would barely run at WOT. I suggest if your are insistent on...
