Thunderwolf Posted July 3, 2007 Share Posted July 3, 2007 i make the throttle quite high at first then just turn it down untill it starts to struggle, then just turn it back a bit then thats it. Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 well with the idle at about half throttle it stays on for about 15 seconds at half throttle then dies .... also there is lots of fuel coming out from around the plug evern thaugh it is in a tights as i can get it Quote Link to comment Share on other sites More sharing options...
dazzi220 Posted July 3, 2007 Share Posted July 3, 2007 there should be a washer on the plug - copper coloured its jus too rich try leaning out the lsn and hsn a bit more, take note of how much u turn each needle and really u should be using a cold plug period.

cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 a clod plug ... would this make the engine run better / easier and yes there is a copper washerforgot to mention im running 25% odonnels in a .25 engine Quote Link to comment Share on other sites More sharing options...
dazzi220 Posted July 3, 2007 Share Posted July 3, 2007 u indicated u need a new plug .21+ engines will be fine on a cold plug for all year round starting and running. TBH I can't be bothered to explain it all nor can I find an old post where I did, hot and medium plugs start the engine a tiny bit easier but cold plugs and will with stand the heat issues during the break in and there after.

Mel Posted July 3, 2007 Share Posted July 3, 2007 sounds like you have got the wrong plug, make sure the one you are using is the same size as the original one because the Turbo plugs i use in the Falcon are slightly shorter that other turbo plugs. i tried using a different one and got fuel coming up around the glow plug Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 im not using a turbo plug ..... should i Quote Link to comment Share on other sites More sharing options...
Mel Posted July 3, 2007 Share Posted July 3, 2007 lol look at the one you got with the engine. did it use a brass washer? Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 i didnt get a plug with the engine Quote Link to comment Share on other sites More sharing options...
dazzi220 Posted July 3, 2007 Share Posted July 3, 2007 turbo's don't use a washer as they're tapered and fit better, they're the same as a normal plug really for what they do but Mel is assuming u need a turbo cos your current one leaks Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 hmmm i will email smd and ask Quote Link to comment Share on other sites More sharing options...
Mel Posted July 3, 2007 Share Posted July 3, 2007 sorry mate i thought you would know if it was a turbo plug or not. what i meant was that even though my engine took turbo plugs they came in different sizes and you can only use 1 size so it could be the same with normal plugs. When i was braking in my engine i couldn't work out why there was fuel by the plug until i noticed 1 plug was a couple of mm longer. i will find out what one the go's is supposed to take Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 cool i did ask on maxbashing a few weeks ago but it didnt post as im on validation and the admins dont like me because i cant spell Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 right well jamie booth recomended i use an os a5 plug (standard) so i will nip to modelsport tomorrow and get some Quote Link to comment Share on other sites More sharing options...
Mel Posted July 3, 2007 Share Posted July 3, 2007 nice one mate hope it turns out to be the problem Quote Link to comment Share on other sites More sharing options...
martin Posted July 3, 2007 Share Posted July 3, 2007 For break in cew i have always used an osa3 hot plug and they do the trick perfect, if you look at the back of the packet it says they are for rich/break in settings. Also having a hot plug on break in will stop the engine cutting out, once its broke in i have found the alrounder os8 plug is spot on for big blocks. marty Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 ahh well i looked on modelsport website and it said that the os3 was for small blocks so i wasnt sure ..... whats the difference between os a5 and the 0s8 Quote Link to comment Share on other sites More sharing options...
martin Posted July 3, 2007 Share Posted July 3, 2007 They are slightly cooler than an 8 mate heres a link to understand os plugs better. clicky hope this helps your break in, it can be a right pain in the butt sometimes you just got to take your time doing it and not loose your rag. marty Quote Link to comment Share on other sites More sharing options...

cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 well ..... i after about 3/4 turn leaning on the lsn and half a turn on hsn i got it to run and idle but it dies when i take the glow start out and its smoking at idle even after all that leaning .... i set the idle gap to about 3mm and opened throttle to about a quarter .... should i lean it out more or what Quote Link to comment Share on other sites More sharing options...
martin Posted July 3, 2007 Share Posted July 3, 2007 well ..... i after about 3/4 turn leaning on the lsn and half a turn on hsn i got it to run and idle but it dies when i take the glow start out and its smoking at idle even after all that leaning .... i set the idle gap to about 3mm and opened throttle to about a quarter .... should i lean it out more or what To much on the lsn mate 3/4 is way to much they are so more precise than hsn, as for the hsn not enough, turn hsn in by 1 turn it won't hurt it, the 3mm gap mate is to much it should rev like made at 3mm unless your really lean and it cuts out. to be honest cew i think its still to rich thats why its cutting out when ignitor comes off. i know what your thinking "so why did he say its to much of a turn on the lsn". this is because the hsn is the main jet where the fuel comes in so if you have a rich setting it will be automatically rich on the lsn even at 3/4 of a turn in on lsn it can be rich if the hsn is set to rich. I would seriously give the hsn at least one turn and maybe the lsn 1/8 and1mm gap on the carb. if you have smoke at high rpm your ok mate. marty Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 ok well 1/8th lean on lsn and one full torn on hsn didnt do much as i couldnt get the car to start but i will richn the lsn up by a half turn and lean the hsn by a half turn and try again 2 morro Quote Link to comment Share on other sites More sharing options...
martin Posted July 3, 2007 Share Posted July 3, 2007 What are the base settings for that engine mate? Sounds to be a bit of a pig to tune. marty Quote Link to comment Share on other sites More sharing options...
cew27 Posted July 3, 2007 Author Share Posted July 3, 2007 i dont have a clue ..... it isnt a pig to tune .... i just cant get it lean enough to idle ... and im scared that if i lean it too much i will damage the engine Quote Link to comment Share on other sites More sharing options...
