oldmanstoner Posted July 30, 2010 Posted July 30, 2010 Hi guys im glad i found this site was readin a few topics and then joined i blew my head gasket on my dt and replaced it i stripped the whole bike down and rebuilt it but when i start it it just revs what could that be the slide in the carb that doesnt close because it is the wrong way or could it be something els and what spark plug should i use and when i tried to start it again i wont start i started it a few time while reving high and turned it off but it wont start again
Moderator Airhead Posted July 30, 2010 Moderator Posted July 30, 2010 You had the barrel off? and when you cleaned off the old base gasket you left a teeny weeny piece of gasket by mistake now that piece is causing an AIR LEAK This is of course a guess Have a spray around with WD40 and see if it affects the engine speed / tone, this may point you in the right direction to find the air leak. Feel free to intro yourself in 'The Bar' ...Paul

First of all, who are you? Introduce yourself! male/female. Where do come from? put a few punctuation marks in your sentence. It sounds like you are trying to say it in one breath. Don't come in all "Gung Ho" and you might, might, just find you will get a little bit of help, but the way you are going I think you will be ignored.

oldmanstoner Posted July 30, 2010 Author Posted July 30, 2010 My apologies. Iam a male and live in South Africa. When I put the head back on, I made sure that it was clean I sprayed DW40 but that didnt help. Any other suggestions would help thanks
Moderator Airhead Posted July 30, 2010 Moderator Posted July 30, 2010 I didnt say head, I said base...that's cylinder base.

Moderator Airhead Posted July 30, 2010 Moderator Posted July 30, 2010 You have an air leak Possible places are 1: Carb slide is not bottomed for whatever reason have you put the slide in the right way round with the cutaway facing the filter box? 2: Cylinder base gasket not sealing 3: Cylinder head gasket not sealing 4: Leaking reed valve manifold joint or carb to intake boot joint 2,3 and 4 Can be investigated by spraying WD40 around the relevant places

Vez Posted July 30, 2010 Posted July 30, 2010 Thanks changed the side and it now works thank you Can you be a little more clear as to how you fixed it, as it may help someone else out who finds this thread. What do you mean by changed the side? Vez.

What do you mean by changed the side? Vez. I unscrewed the cable that goes to the carb from the accelerarer cable there is a long groove that runs up the side of the slide in the carb with a needled attatched to it. I put that long groove on the same side as the air box and then scrwed it back on. Cleaned the plug and started fine.tym to ride
