ATC 70 3 wheeler Restored engine rings, cam chain tensioner gasket set brakes bearings etc
Bike ran good untill My son tore the bike apart to sand blast and paint frame and fenders
Since then it will not fire It has points and condenser that are new changed out after not be able to get it to fire
This is what it does do I can hold the coil wire in my hand and when the recoil starter is pulled it will knock the crap out of me but still not fire thru the spark plug tried several plugs also stuck plug into end of coil wire by passing the spark plug cap
Any and all suggestions etc appreciated
Thanks in advance
This may help.......Make sure the coil is grounded to the frame....... Sand the paint off where it contacts frame...... Check the wiring with the diagram below.
Also sand down the frame where the engine mount holes are, the engine may not be grounded to the frame.

I know have another parts bike atc 70 and a trx 70 so that equals 2 atc 70 s and 1 trx 70 but know will run
Ok I took the top coil off the bikes 2 of them brought them to shop and had them tested one had very good fire and one very weak fire.
The one that had weak fire I peeled the coil wire back to naked wire and spark jumped from the end of the naked wire to the fins on the head but when put on a known good plug and cap will not fire thru Any sugestions please post up
Thanks in advance Jim
