2014年1月30日 · EXAMPLE: factory specs call for B8ES plug: B7ES - 1 step colder plug (for easier starting in warm temps) B8ES - General all around use (factory spec) B9ES - 1 step hotter plug (use in -0 temps, or if fouling spec plugs) By switching between the heat ranges, you keep running with optimum spark.

2011年8月7日 · I'm trying to find what the correct gapping is for this 440 reed valve with a NGK BR9ES plug. I've been running B8ES with no issues but that's what was in it when I bought it. Anyone still have an original owners manual???

2008年1月1日 · What kind of plugs did you put back in? Sometimes some of them take a little time to turn color. Try running at the speed you would normally run or say about 50mph for a long stretch if you can, around here about the longest is a mile, shut it down and check the plugs.
