I am not sure plugs make a difference in performance, but... Autolite has a new line of iridium fine wire plugs for small engines. I use fine wire plugs not to increase performance, but to enhance longevity of electrical componenents in older ATV's and motorcycles. Same spark, less effort to do...

There are some products in marine applications that claim to revitalize, clean and stabilize gas through the use of enzymes, not solvents. But that is not what this is.

I went 10 on one but it was not OHV, with more recent models..... They are overhead valves with mechanical lifters. If they go out of adjustment, they can lead to hard starting wich will lead to coil and starter trouble. Which further complicates starting. It is a known weakspot in an otherwise...

Walt at garden Web e-mails the instructions out. I have detailed instructions for adjusting your valves as well as trouble shooting at address below, put in proper format. Walt Conner wconner5 at verizon dot net I will attempt to scan my printed version in and post here tonight

I believe Flanso is correct, The clutch would appear to be working, and it is idle Clean the air filter, new fuel. If no gains then I would richen both the low and high mixture a 1/8 turn out and readjust your idle (turn out to slow)to where the chain will not spin at idle The leaner the mixture...

I have a generator with a clone by Jiang Dong 6.5 HP. It runs at mission trip work sites right along with my Honda, and ran a freezer and TV 7 days on and off during IKE. No problems. Rotella 5-40 synthetic and stored properly after every use. I am probably pushing over 100 hours, If it blows up...

Originally Posted By: Jaymus I've got time. Don't have a feeler gauge. I've seen my dad adjust them on SBC's all the time. He did it by ear. I never learned lol. No valves by ear, it is feeler guage (gap), like on a spark plug. High and low idle by ear if no tach.

I use seafoam aerosol deep creep. It is one of it's listed functions. I just bought aerosol fogging oil and will give it a shot. First smile of the day fsskier! Certain products develop some intense loyalties. MMO is one, and it's uses are just behind WD 40 or Duct Tape.

FWIW Seafoam and flushes did not do as much as a new PCV valve and Valvoline Maxlife 10W-40 in one of my kids 96 dodge stratus. Went from 1.5 quarts per 1000 miles to .5 quarts, when switching from Supertech 5w30. It has become our test lab. Penzoil HM and Supertech HM have a slightly higher...

UOA's, synthetic oil, 16$ filters and "Peace of mind for my Briggs and Stratton v twin" ...................For the love of lawn tractors, We are a sorry lot

Originally Posted By: yeehaw1960 Oops, my soapbox broke. It must have come from Lowes! Yes the box store equipment is not as well made and will not hold up to commercial use. But they share similar components. The carbs are made by the same people. If you have some skills with small...

Cujet and TDIRick know their stuff, and have cited tests that show that extreme high ratios may not be best for wear and have lower HP. I run Stihl HP synthetic at 40:1 (a 50:1 oil)for everything I have(ratings 16:1 to 50:1. I should probably go to 32:1, based on what they say, but am hard...

Air leak as stated earlier. If manifold is not the culprit (Carb to cylinder connection) tighten the bolts on the bottom of the saw. They hold the case/jug together. They can vibrate loose. good luck
