Another way to decarb your engine.

[johnm]

Hi all,<br /><br />The normal way of decarbing an engine is to run some sort of engine cleaner through the carbs revving it slightly and then going WOT for 5 - 10 minutes...or something similar.<br /><br />Yesterday, I found out another way, apparently the "proper way" from a mechanic who's been in the biz for over 40 years. <br /><br />1. Crank engine and warm up for about 15 minutes. <br />2. Switch engine off<br />3. Pull sparks<br />4. Tilt engine right up as high as it can go<br />5. Spray a can of engine cleaner down the spark plug holes, moving the flywheel by hand as you're doing so.<br />6. Once can empty, leave the contents of the engine cleaner to sit for 6 - 16 hours.<br />7. Take boat out to water. Start engine then go WOT for about 5 minutes or so.<br />8. Then, while engine is running throw another can of engine cleaner at the carbs this time round. Go at WOT for another 5 minutes.<br /><br />Apparently, this method fixes all sorts of problems such as stalling, choking and coughing. It's also supposed to fix problems for engines that run fine when cold but play up when warm(Exactly the sympton my engine is having).<br /><br />I'm yet to try it out as I'm still waiting on a jet for my carbs, but keen as mustard to give it a go as fishing season is nearly over.<br /><br />I havn't come across this info on this forum as yet and I have done a number of searches on "stalling" and "decarbs". I thought I'd share this information with everyone out there.<br /><br />If anybody has tried this method and fixed a problem please let me know. Alternatively, if you are already familiar with this method and I have missed a step, please advise.

Yeah, and I bet you can lose weight while watching TV and sleeping and improve your sexlife at the same time. Decarbing, even an improved method if there was one, is only going to work if your compression is low due to stuck rings and won't do much of anything if that is not the case.

The main reason for the decarb is keep carbon from building in ring groove, and pushing the ring out, where it will hang in the exhaust port,and break the ring, helps some other problems also. The varnish junk that you see in the carbs will build up on the cylinder walls, clean this off.

Re: Another way to decarb your engine.

Decarbing is a 3 step process.<br /><br />1. Use a decarb fuel additive to help prevent buildup.<br /><br />2. Spray a decarbing solution into the carbs of the running engine.<br /><br />3. Pull the plugs, spray, soak, run engine.<br /><br />You should do all three to do a thorough job. It should free up the rings and remove deposits that can cause detonation. Search this forum for the specifics, it has been covered extensively.
