About Pull Start- Potential Problem.
Hey fellas, I got a pull start adaptor from Zoombicycles.com But I have a question about it. When installing the metal plate. Does it matter if the metal touches the magneto coil screw? Will that short it out? I had it running, today but strangly, it stoped so I decided to chain the Mag Coil b/c that is what I thought it was then it worked again. WHat do you guys think?

Put the lock washer under the pull start bell and use lock tight on the nut...POPS
Ps. Aluminum is not an electrical conductor.

Re: About Pull Start- Potential Problem.
Aluminum IS a conductor and was used in manufacturing of residential wiring during a copper price hike in the 70's . It also degraded over a short time compared to copper and caused fires , that was when it was discontinued as a residential product .

Bare aluminium wire is used for ALL HIGH-VOLTAGE CONNDUCTORS. You know, the ones going from metal tower to metal tower. So yeah, aluminum is a conductor.Don't want any of you guys touching the wrong thing. Walter F.

Re: About Pull Start- Potential Problem.
Walter sent me a pair of pull start units to inspect.
One had a stamped sheet metal driver, the other was cast Aluminum.
The sheet metal piece just barely cleared the screws, the cast one wasn't even close.
The pull starter that came with the sheet metal driver worked great until the grommet for the cord popped out. I didn't realize the grommet had come out of the housing. The edges of the casting are so sharp that the cord shredded after a few pulls. No big deal, I put new cord in and made a nylon grommet that will stay put.

Quite right- it is a very good conductor (after silver and copper), but corrodes.

Re: About Pull Start- Potential Problem.
Ok, So does it matter if the Pull Start Plate Adaptor touches the screw of the magneto Coil? Will that short the Mag Coil? When I pull started it when it was touching there wasnt any resistance or anything, and there is a lock washer but it still seems to be touching A LITTLE. Any Recommendation, and will that short out the Mageneto coil?
