Thanks m8 its correct then

Gents my rubber compound boot that fits in with the reed vales. The thing that directs the fuel down into the reed vales only has one prong to it. Is this correct or should it have two prongs

Purchased one today m8, should get it by monday

Gents took the reeds out and they look new. Had a look a the spark plug and it looks like this

Hi gents, Have just had new bearings and seals in the crank. Carb is all standard. (Correct float hight?) Engine is running much better but apears to struggle to idle.

Its had new bearing and seals but will re check. cant look until tomos

Well i can only look for air leaks. Not sure what else it can be. I take it ylu judt let the needle slide cut away bit hit the bottom and then ajust throttle bable to suit. Then idle screw?

160 main jet, its a 130 standard on the 175 ) Thats the carb now fitted m8. with new internals

Its a 1978 but will check if its points and reed valves tomos.

Hi all, DT feels like its missing between 3 to 5 thou and isnt crisp at all, very spluttery. Engine is very quiet with no knocks or rattles what so ever. It will still pull to 65 but it dont like it. will clean carb but whats standard settings Also have the same problem with this bike as 175. Cant get driving lights to work? All other light function. obviously i have the bike running and have checked fuse but now joy:o(

DT175mx runs much better now ), very crisp but i am struggling to get it to idle? air screw set 1 1/2 to 1 3/4. It either dies or its above 2000rpm. adjusting the idle screw Still need advice on the 250mx. Feels like its missing heavily around 3 to 5 thous. Not very crisp either. bit sluggish. Any advice would be great.

cheers oldgit, ;o). Doing what you said. Have taken a loan out now so may keep it. But also managed to pick up a dt250 so will have something to mess with. Can you tell me standard settings for the carb dt250 mx 1978. Runs ok but feels like its missing around 3000 to 4500 revs. Hit it all the bloody time.

I can blow through it but you dont get a massive blow through. Have put some tiolet cleaner in it and will power wash it through in the morning. Will also put original carb back on tomos.
