    There are opponents to castor oil and will fight to the death that castor oil will cause every problem known to model engines if you use it in a 4-stroke and frankly that just isn't the case. ...

    The throttle doesn't have to be open more than idle speed to prime it provided the idle needle isn't set too lean and/or the idle stop set too low (idle gap too small). If an engine won't prime with...

    If stored for a long time, castor will gunk it up. If you oil the engine before storage, it won't gunk up. I use 20% castor in my 4-cycles with no issues. I oil mine up with ATF before storing and...

    The muffler pressure is very very low at low throttle settings though, so the engine needs to draw fuel on its own, essentially, at idle.

    As the piston travels up and the crank inlet opens, a low...

    Just because the instructions say one thing doesn't mean it's right. No skin off my nose if you bolt the engine to your plane and put it in the air for the first tank. It might run like a Swiss...

    Anytime I have an engine that is normally reliable and runs well and all of the sudden doesn't run properly in a different craft, 99% of the time the fuel system is to blame. That's why I suggested...

    If using a 3-line setup with two clunks, you may encounter issues. I did when I tried it with an ST S90. When coming off the throttle from WOT the pressure line would fill with fuel and the engine...

    That's likely not a major issue. I'd still pull it out of the plane.

    Whenever you have a misbehaving engine, put it on a test stand with a known good fuel system and run the engine. If it runs okay on the test stand then you know something is amiss in the aircraft. ...

    I kinda wish more car engines came with those prop drivers. Breaking in a car engine with a prop is so much better than in the car. Really it is the best way to run in an engine as you can run it...

    I have an Enya .60 4-cycle that I'd love to stuff in an LST2, but the 13,000rpm limit will make it a slow toad. Need a 2:1 or 2.5:1 transmission of sorts. It's down the road a bit. I'll...

    Unless they test run them, the piston ring, Rod ends, bearings, etc. all need to bed in. Especially the piston ring. Engines rarely run like they're supposed to until that ring is seated. I am one...

    Believe it or not, that's what I've done when doing a U-Joint. And I'm just a stupid uneducated redneck from Minnesota. Haha. ;)

    I do too, but the OP doesn't. I do find it odd that an RC car engine came with a knurled prop driver behind the flywheel and clutch. Makes me wonder if it would be that much easier to get a clutch...

    I don't think any recent or current models of RC cars come with 4-strokes anyway.

    The CPI setup is similar to the Vortec 305 & 350 - the injector system used a central injection pump of sorts with little electronic injectors with plastic hoses going to each injector. The v8...

    Too bad - the 4.3 was a 350 minus two cylinders. The CPI 4.3's were the good ones. TBI - not so much.

    2.2l or 2.5l? Mine had a 2.8 v6 which may have well been a 4-cyl. At least it had a 5spd behind the 2.8.

    My buddies said it was wussy unless it did wheelies. I guess it'll stay wussy. It's hard to get traction with 350-375hp as it is. When I get new heads and EFI on it it should push 400hp which is...
