trialsrfun Posted March 22, 2015 Report Share Posted March 22, 2015 What spark plug are you fellow Triumph Cub riders using please, is one with a projected nose better or stay with the ordinary type, if NGK should it be a 5 or 6 heat range?

trialsrfun Posted March 23, 2015 Author Report Share Posted March 23, 2015 (edited) I have been running it with a NGK BP6HS and lead replacer fuel additive at the recommended ratio as on the bottle but have problems with rough running due to a carbon trace forming between the tip of the electrode and earth wire on the spark plug. I believe that the LRP additive is causing this plug fouling has anyone else had a similar problem?

jon v8 Posted March 23, 2015 Report Share Posted March 23, 2015 And the same to you Sir! Sorry, couldn't resist it ! I think the joke always was a petrol cap for a Skoda... Which is where the problem is because my current work truck is a Skoda pickup. 2 Quote Link to comment Share on other sites More sharing options...

totalshell Posted March 23, 2015 Report Share Posted March 23, 2015 why are you using a fuel additive.. no one else does.. Quote Link to comment Share on other sites More sharing options...
jon v8 Posted March 23, 2015 Report Share Posted March 23, 2015 Hi Jon, Don't you mean a VW Caddy in fancy dress? Deryk I don't know Deryk, I thought the Caddy was the one in fancy dress... I'd rather have an 80" series one Land Rover by choice, but they are a bit more than the £500 I paid for Cloda the Skoda ! Quote Link to comment Share on other sites More sharing options...
trialsrfun Posted March 23, 2015 Author Report Share Posted March 23, 2015 (edited) why are you using a fuel additive.. no one else does.. I am now thinking this as well so no more additive and I think no more plug issues. By the way Jon I learnt to drive in a Series 1 Land-Rover when I was 11 or 12 years of age, it was a 1952 model with the red and yellow range change levers 1500cc side and overhead valve engine Edited March 24, 2015 by trialsrfun Quote Link to comment Share on other sites More sharing options...
trialsrfun Posted March 24, 2015 Author Report Share Posted March 24, 2015 The additive is meant to cushion the mechanical collision between valve & seat providing the same protection to these parts that lead did when it was part of the fuel.

totalshell Posted March 24, 2015 Report Share Posted March 24, 2015 so i ask again.. why in a low reving low usage engine are you using it.. no one else does. 1 Quote Link to comment Share on other sites More sharing options...

For the above reason but from now on just fuel followed by more of the same. 1 Quote Link to comment Share on other sites More sharing options...
