7016 issues

Recommended Posts

I've been working on a 7016 with a Briggs 16hp engine and large flo-jet carb. Also poking around here, great site!, and have become a Simplicity, AC fan. I bought the 7016 because of it's versatility, and I like old cars and machinery. The deal included a trailer, cultivator and Mighty Mac chipper. The rust bucket MM will be a project. I've found some issues that I think would make the engine cut in and out, idle to full throttle, and just wondering what you guys think. I found: 1) no carb runner to governor bracket gasket 2) no gov bracket to engine block gasket for carb runner 3) carb runner to carb body gasket partially blocking the runner opening 4) carb welch plug loose 5) throttle bushings with too much clearance - woobly 6) coil armature clearance of .006 instead of .010 to .014 7) a scuffing sound coming from under the flywheel cover. #1 & 2 aren't in the carb kit so I'll make those. Probably not a big deal in terms of the issues, but it will eliminate unaccounted for air leaks and dirt. #3 Replaced the partially blocking gasket. Again probably no an issue. #4 Replaced the welch plug, staked with sealer around outer edge. Probably just an unfiltered air issue since it is before the carb. #5 Replaced bushings during carb rebuild. It was pretty clean and the float seemed empty (yeah!). This could be a big issue except for #6. I noticed the p/o had the idle fuel kind of fat. #6 Adjusted armature to specs of .010 to .014. #7 I found a slight amount of rubbing on the outside diameter of the flywheel. Only in a couple of places though. For #6, I noticed a tiny, tiny build up of surface rust. This is almost unnoticeable. I'm thinking this might have accounted for the gap difference, and am thinking of giving it a slight brush off with 240 or 400 grit, paying close attention to the magnet and removing the particles, and then a very light wipe of fogging oil or cosmoline. I'm replacing the head gasket also. Looked like a leak issue, but turned out to be a build up of blackened oil in one suspicious spot. I was really curious to check the head and piston's carbon build up, valve coloring, and cylinder wall anyways. All look proper, heck there's even some factory cross hatching toward the front pto end. Valves clearances are on spec. Compression around 60 - 65. Thanks for reading this long posting. Any cautions and recommendations?

Thanks. The nickname was given to me by a military friend. I think it's important to write some memoirs about service for family history, and thank those vets you meet. I'm in the process of cleaning and painting this 7016. I found the Valspar International white to be a match for the AC white.

Good to know about the paint. A correction on compression. Checking my notes, compression is 60 on the first stroke, 90 on second to the fifth. I'm down to the steering and rest of frame on painting. Over the years I've turned the ugly into fantastic, but it still amazes me how good things look after some tlc cleaning, preping and painting. Then comes the task of avoiding scratches during reassembly!

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul

      I assume it's a bosche, correct
