RogerH Posted April 17, 2021 Report Share Posted April 17, 2021 Hi Folks, I got the BlueRacer out from it's winter slumber this morning It is always fun getting it started for the first time in 6 months. This morning was a little better. I removed the plugs and spun the engine over to get the oil moving. Add a squirt of 'Start ya Bas...d and it start on the button. The battery did well. However there was a misfire on #3 plug. I found that if I removed the plug lead and held it about 6mm away the plug fired up. So I then opened the plug gap from 0.025" to 0.040" and it runs a treat (Champion L87 plugs) The NGK straight plug caps are about 5 years old but have done very few miles. I will get new caps on Monday. Any other ideas out there for me to consider. Roger Quote Link to post Share on other sites
Waldi Posted April 17, 2021 Report Share Posted April 17, 2021 Hi Roger, It may be a petrol issue?? Maybe the std gap (0,025”) did not give enough spark, the larger gap did? Anyway seems your ign. system is good. Cheers, Waldi Quote Link to post Share on other sites
RobH Posted April 17, 2021 Report Share Posted April 17, 2021 Very odd. It might be indicative of some sort of tracking on the plug or connector. Opening the gap might be a red herring - perhaps you cured the actual problem unknowingly when taking the plug out. Quote Link to post Share on other sites
RogerH Posted April 17, 2021 Author Report Share Posted April 17, 2021 Hi Rob, all things are possible. I had the cap on and off a number of times and it was nly when the gap was increased was there a 'permanent' fix. I shall buy new caps next week and see if that does the trick. roger Quote Link to post Share on other sites
Lebro Posted April 17, 2021 Report Share Posted April 17, 2021 I agree with Rob, widening the gap would make the plug more likely not to fire. Bob. Quote Link to post Share on other sites
RogerH Posted April 17, 2021 Author Report Share Posted April 17, 2021 Hi Bob, I agree, but something is changing the physics. Early next week I shall have new caps. Roger Quote Link to post Share on other sites
Waldi Posted April 18, 2021 Report Share Posted April 18, 2021 Aha, now I understand the issue, it is NOT with plug installed. Weird indeed. Waldi Quote Link to post Share on other sites
