Hi All
I am having a problem with my mc21. It has had a full rebuild now it wont idle , I start it up with choke it is OK turn the choke off and after about a minute it will stall. Before it droped the big end bearing it was running fine.
Just before it stalls it will go splutterey then stall . If i rev it sounds good but when goes back to idle will go down to 800rpm then go back up to 1200rpm .
I have cleaned the carbureters out no change
I am running hrc jet kit ,Hrc delimiter ,no airbox yet,changed crank, new piston ,rings
This problem has got me stumped has anyone had the same problem or any suggestions of what the problem may be
Thanks All
