felixx Posted April 27 Author Posted April 27 So I think I got all the airleaks sorted, she idles and runs better Lots of rust on the chrome.. Hit it with a brass wire wheel and crc.. Came up lovely 3 Quote
felixx Posted April 27 Author Posted April 27 She is coming along well I will try and get the black plate on her.. 7 Quote
felixx Posted April 28 Author Posted April 28 So once she is warm, she runs well but takes 100s of kicks when cold. She backfires but wont start until she does Thinking: Valves clearances Timing Points and / Condensor All of which I dont know how to do, but I do have youtube. When its warm it goes well but will eventually just die if left to idle for more than 2 min What order do you suggest attacking my list? Is there anything more to add? Quote

Certainly clean / check the points (and points gap) is the choke flap closing properly? It will definitely need choke to start when cold - does it start better with a shot of easy start? 1 Quote
Lord Gruntfuttock Posted April 30 Posted April 30 When it's cold check for spark, and fuel. If it has both, a compression test might indicate valve issues. Could be as simple as finding the choke position it needs to fire. If the plug is wet it could be flooding. My CTs the same, takes a million kicks when cold. Pull plug and dry it and it normally gets going. 1 Quote
Tumeke Posted April 30 Posted April 30 Charge your battery? The old C50s need voltage to make them excited. They're better when up and running. 2 Quote

Hmmm I will be checking valves as it starts easy when warm, there is a little smoke, but this could be a rings issue.. borrowing a compression tester tomorrow morning, hoping its not rings just for the sheer buggery involved 21 hours ago, mo999 said: Certainly clean / check the points (and points gap) is the choke flap closing properly?

Tumeke Posted May 1 Posted May 1 i would encourage a CDI upgrade on this bad boy if you feel like a challenge. Lifan parts should bolt on from memory. Quote

A multimeter and a 6v bulb are really handy for timing them per the honda workshop manual. 1 Quote

So I guess a stator and 'starting loom' off a Lifan will be whats needed with a CDI, Guess that is converting the Cub to 12v as well I have a couply dead 90cc lifans hiding somewhere, could scrounge em off them?
