Ok after putting the old exhaust on, had to double the exhaust gasket to get a good seal.
Gapped the plug back to .030 as mentioned earlier (yes, again today), wouldn't even bother trying to start unless I was going at least 10mph. Seems like the smaller the gap I get, the easier it starts, runs for a second and stalls itself out. Been playing with the needle settings, too, since I've hollowed out the stock air filter box (black nt punisher looking one).
Gonna pull the magneto in a sec, get pics of the magneto plate studs sticking out on the flat side and grind them f***ers flush to the plates. Been playing with this thing off and on all day today and I still have to go to work lol
