Coil gap off fly wheel

[Iggy]

I'm working on an MS 270 my uncle sent to a shop recently where they replaced the coil. He said its not running right, warms up and dies. I took it, it starts idles poorly. Checked inside carb, air filter, tank breather, changed fuel, reset carb to factory, and it likes to flood. Checked spark and didn't get any for a while, now I get spark but I'm looking for how far off the flywheel the coil should be, thanks in advance.

Business card is usually the standard gapping tool.

Sounds like the coil is fine, I would go back to that shop and insist they fix it correctly, since they bought a ticket....

 

[Fish]

Or had your uncle pay for the ticket......

I thought about having him take it back but I was already in the saw, wanted the trouble shoot experience and I didn't have any real measurement of gap previous to me loosening it. I just told him not to take it to as shop anymore. It cost him $100+ for a coil

I also have another issue I don't believe to be related to the shop. It runs for a bit then dies I think it's going to need a carb kit
