tanveer Posted May 19, 2018 Share Posted May 19, 2018 (edited) Did a couple of 5 minute heat cycles and then ran it for half a tank to run the engine in, put it away and tried to start it today and its just flooding itself. Took the spark plug out and it seems clean and its sparking. un plugged the killswitch to check that and still wont run. Iv checked all the usual things like fuel cap vent hole, head bolts etc and all seems tight and good. Carb is at factory settings. It does ever so slightly cough every now and again like its going to start but then wont run, the plug is always wet and stinks of fuel when i take it out. Iv even tried both methods of un flooding it by removing spark plug and pulling a few times with the truck upside down, and removing the carb and trying to start it OBR style, it still didnt start after trying both these methods. Anyone able to help with any other bits im overlooking? Its a brand new engine and iv never had problems with any petrol engine like this, so im not too sure if theres anything im overlooking Edited May 19, 2018 by tanveer Quote Link to comment Share on other sites More sharing options...

supersavage Posted May 19, 2018 Share Posted May 19, 2018 Where are you in Leicester? If you're still having problems your welcome to bring it round (if you don't mind dogs) or meet up somewhere at some point as I have a few used but usable plugs we can try and a couple of carbs as well. 1 Quote Link to comment Share on other sites More sharing options...

tanveer Posted May 21, 2018 Author Share Posted May 21, 2018 Just to update the thread, turned out to be a dodgy spark plug. It was sparking when put up against the cylinder so not sure what was going on. But as soon as i stuck a new ngk in there it fired up first pull. Bit iffy how rc modelz are advertising these as coming with "ngk performance" plugs but mine came with a chinese torch spark plug....

kenny_st Posted May 22, 2018 Share Posted May 22, 2018 guys at my local track said the same thing about the plug and the fact it only lasted a few heat cycles but even the best plugs don't last long after the running in period anyway Quote Link to comment Share on other sites More sharing options...

Il be keeping a couple spare cmr7's with me whenever I take it out from now on though. Quote Link to comment Share on other sites More sharing options...

Leci Posted March 19 Share Posted March 19 How long does a spark plug last after the break in cycle on a 30dn truck Quote Link to comment Share on other sites More sharing options...
JonnyUK Posted March 19 Share Posted March 19 (edited) A faulty spark plug won't spark when under compression. Had it a few times on motorbikes, cars etc. That's why most garage mechanics will first fit a set of spark plugs when fixing a non runner.
