Hello all! I'm new to the site and new to the world of the 6x6, but I've been riding and rebuilding bikes and atv's since the age of 11. I just thought I would chime in and share my experiance in getting my max up and going.
So, I brought home my 2000 Max IV a few days ago with an 18hp vangaurd twin. I knew it had sat for some time and had 4 year old gas in it, but it still ran and I was able to drive it on and off the trailer and over into the field across the street. I had put 4 gallons of fresh gas in it (plus a bottle of HEET), thinking it would improve it's running condition. Well, it still felt WAAY underpowered. I had to run the choke half open just to keep it going, so I was sure it had carb issues. It would hardly even turn without stopping and almost dieing. So, I pulled the top of the carb off and it was surprisingly clean! I went ahead and blew everything out and put it back together hoping it would help, but it really didn't. So, next I dropped the tank. It was LOADED with dirt and junk, so I figured surely it was clogging the supply and starving the engine for fuel. I cleaned it all out, blew the line out, and put her back together. You guessed it; no difference. SO, I thought, "Maybe the chains are too tight?" Got them all checked out; no problems there. Well, after hours of screwing with it I'm standing there scratching my head while it idles and I think to myself, "Did I ever check the spark plugs???" I reach down and pull the cap off the rear facing cylinder and the idle doesn't change one bit. Sure enough, I put it back on and pull the other side and it dies. After all my fiddling I found it was only running on one cylinder! I put a plug in it and it smoked for about 30 seconds while it burned all the junk out of that cylinder. I went for a test ride and WOW!! What a difference!
I was starting to worry that it was just a dog and had no guts, but it's a beast and a blast to drive now!
Anyways, the lesson here is to always check the simple obvious stuff first. This is something I've always known, but this was definetly a reminder...

well they did look ok and would have run another 20,000 miles in a car, but the relative small output of the briggs coils needs plugs more often.
