Flatheadpete 183 #1 Posted September 26, 2014 I really enjoyed the misquito control when I mowed with my '66 WH 856 this summer but I think it has to stop. Before I bust this thing open, any tips or tricks or usual things to look for? I recently purchased a new (!) lawn tractor for mowing duties so I can afford the downtime for my WH. But, I still want to plow snow with it. BTW.....Did I mention it smokes BAD? Share this post Link to post Share on other sites
rmaynard 16,344 #2 Posted September 26, 2014 The K181 on my 857 smoked like a chimney. I pulled the piston and measured the ring gaps and had over 1/4" gaps. I honed the cylinder and installed new rings and the smoking stopped. However, that's not to say that that would be the problem with your, but it is a starting point.

Fordiesel69 271 #3 Posted September 26, 2014 There are alot of times rings will fix the problem. If the engine also has a slight knock, it is best to do it all while your in there. Share this post Link to post Share on other sites
Flatheadpete 183 #4 Posted September 26, 2014 Runs like a watch but just smokes. I plan on new rings but will completely overhaul it if need be. Thanks, guys. Share this post Link to post Share on other sites

slammer302 2,156 #6 Posted September 26, 2014 I would say one thing to not over look is the valves if it is smoking as bad as you say the valves are going to be caked with carbon I would say at the least take them out and inspect them and clean them up the cheap eBay kits come with new ones Share this post Link to post Share on other sites
WH nut 553 #7 Posted September 26, 2014 I always recommend a new rod any time you replace rings or piston. The extra stress on the old rod can cause it to break. Share this post Link to post Share on other sites
