Question about Radio Communications

1 Answer

I recently acquired an old Cobra 78x from my father in law. It was sitting in a shoebox in his basement for over 8 years and when I fired it up I noticed that other users said that my transmission was crackly. It will be clear right away but quickly becomes annoyingly crackly and staticy on every channel. I tried a different mic and it still happened. Then I tried a different antenna...still happened. Then I resoldered every connection that I could see...3 hours later still the same problem. I have no idea what is wrong with it!

Change the plugs? Might want to have a professional go over your new ride to make sure all is well. You did a good job ... you don't want to suffer a break down away from home. The tune up will be less costly than the tow job.

I took my father in law's Remington 1.25hp


PRAY! NEVER BORROW a father in laws equipment!!!! Let it sit for a short time and cool down and then see if it will start. I would also check the air filter and make sure that it isn't plugged!

Hobart 10,000 has been sitting for about 3 years and won't start any suggestions?


I know this is an old post, but I just had this same situation. Inherited a unit from my father in law and it had be sitting about a year. I drained the gas tank (disconnect fuel line and pressurize tank inlet with shop vac) and flushed out fuel lines and replace fuel filter, air filter, oil and filter. Cleaned and lubricated all carb and choke mechanisms. Sprayed a bunch of carb cleaner and let it soak. Put in fresh gas. Cranked and cranked and cranked. Did not start right away, but stuck with it. I put some gas in a syringe used for injecting meat (just so you know the size) and remove everything above the carb venturi. Put about 1 cc of gas directly in the carb and cranked. it started and ran until that gas burned up (about 2 seconds). It ran ok but wasn't getting fuel so I suspected the fuel pump. Kept at it and repeated this about 15 to 20 times and noticed that it would run just a wee but longer each time. Until finally it caught and ran strong. Put everything back and it is in great shape. Hope that helps. Also, I noticed there was quite a bit of moisture in the muffler. This sputtered out until it got out enough to evaporate it all out. I now keep it covered when not in use - something I am not sure my father in law did.

Have a 1985 ford f150 302 efi v8 need to know the firing order?


1-5-4-2-6-3-7-8 The rotor turns counter-clockwise. Make sure to keep #7 and #8 spark plug wires separated. The 5.0L had a problem with 7 and 8 cross-firing because they fire so close to each other. Ford changed the firing order on that engine, in later years , because of that reason. Hope this helps ya... Cobra :-)

Once you plug it in, most the time you need to reset the modem and the router together, Unplug both let sit for 2 min then plug in the modem first then the router a couple seconds later. If your modem has a reset button, reset it!
