Several times I have been looking for some advice or tips on some project or hobby that I have been working on but felt like starting a thread on the topic would be kind of wasted. Besides that, it may be tough to find later, or if someone else remembers that it was covered earlier but needs the information now.
This thread is for posting questions that are likely to be answered by a Subject Matter Expert (SME) or wannabe SME (WSME), a Jack of All Trades (JAT), or JAT Master of None (JATMON). The idea is that we may not need a full discussion on the question, but just a line or two to get past a sticky spot.
This thread is NOT for giving advice like "Pull your head out of your ass" or other such unhelpful responses. Please keep the advice ON TOPIC and helpful. Off topic or unhelpful responses will be trashed in the interests of keeping an uncluttered Quick Advice thread.
I'll start the ball rolling, since I am stuck on a project.
I am having some minor trouble with a JCB backhoe (1400B or 3cx) with a Perkins A4 engine. It sat for a few years while I was gallivanting across the states for other work. About 2 months before I left I changed fluids and filters and performed other minor maintenance. I have come back full time and have been lightly working it... It's given me one previous issue that I asked advice about, which also should have been a question in a quick advice thread like this. (Solved starting problem. It was a backhoe valve sticking open, so was trying to start the engine as it was being asked to clinch the bucket.)
Current problem... Starts nicely, quick puff of smoke, then almost smokeless as it runs well at idle. 10 to 15 seconds of running at idle and the engine slows slightly, then starts smoking, then runs kind of rough. Not terribly rough, but noticeable.
I have hesitated to go through and replace fuel and air filters (2 of each on this machine, plus 4 more various filters) for a couple of reasons : It's a European machine and they're not cheap, and also that I have very few hours on the filters that were installed a few years ago. I don't expect it is a fuel quality problem because it runs fine for the first 10-15 seconds.
Any diesel expert advice? I'm a shade tree mechanic, although I do enjoy restoring old machines.

I have a Lee .223 shell holder (#4) that I use in my Lee turret press, and the case seems to fit too loosely in the shell holder; when I seat a bullet, for example, I need to put my finger on the case to keep it completely upright. Has anyone seen this? If I buy a shell holder of a different brand, will it fit more tightly?
Pretty sure the answer to every question is "O-rings".

Guessing old iron. Fuel pressure issues. Fuel tank not venting. To much case pressure. Some self advancing fuel timing stuck. Some compression release sticking, or gummed up valve guide.

Serial number puts it about 1989-90. I thought fuel starvation doesn't smoke... Air starvation smokes (among other faults.) Am I off base? Too much case pressure? Is that the same as blow-by and block pressurized, or are you still thinking of fuel? Injection pump case pressure?
I'll check the advance... Didn't occur to me. No compression release on this engine that I am aware of.
Thanks for the leads!

Somebody please help me. My elderly neighbor "gave" me his 20-year old Sears sit-down lawnmower. 16HP OHV Briggs & Stratton engine. He bought a new Deere machine, and figured I could use his. It's dead, of course. Flat tire. The older gentleman is kind of soft in the head, and had recently been changing parts (randomly). The folks at Sears were too happy to cooperate. He tried to start it, to show me it works. Well, it cranked, and then spewed gobs of oil on the driveway. I towed it to my place, where it has sat for months. I would dump it in the back 40, but the neighbor's wife tells me it was a gift from a family member.
I am no mechanic. What are the first 3 or 5 things you would do? Somebody suggested it might just have too much oil, and I should drain it and start again. Any advice welcomed!

It cranked. That's good news.
1.) Drain the oil. Then fill it with the correct amount of the right oil. Check the manual to see how, and what. 2.) Pull the plug. First look to see if the plug is oil fouled. If so, clean it, but do not replace it yet. 3.) Do a spark test. Ground the body of the plug somewhere on the body of the engine. Crank it over. Watch to see if a spark jumps the gap on the plug. If no spark, check the coil and/or magneto. 4.) Once you have changed the oil, and have a spark, replace the plug and try to start it. If it doesn't start, spray some starting fluid in the carb and try again. If it starts, but dies pretty quickly, you have a fuel delivery problem.
Edit: Should have said at the end of 2.)... If you have already changed the oil, and know there is not too much oil in the engine, crank it over a few times with the plug still out, to clear any oil in the cylinder.

Correct on fuel air. Old oil bath sir filter? Pull air filter completely off an see. Also if pump has ele fuel shut off on suction side could be issue. Highly doubt there's a fuel tank lift pump, but check.

Should I cerakote my exocet frame or have it powder coated? A huge pro is I can do the cerakote myself and save money. But I'm not sure of the durability of air cure cerakote, and I'd have to mix the color myself and getting the color where I want could be a headache. Powder coating has tons of colors, but would probably be 800 plus bucks, even more if I end up doing another color on top of a base.

Pull up Eastwood web site. Buy a powder coating kit and powder for less than a bill Hit CL for free stove. Powder coating needs air pressure, low air pressure. Even a hobbyist air brush compressor will work. Now, you can play.
