It's stuffed. I'll give you $500 bucks for it.

How deep was the Bog? You may have sucked some shit into the carb causing the starting issues, also check the carb drain tubes if they're blocked with crap the engine gets fuel starvation making it stall and hard to start.

Clean air filter and carb I would guess

the plug was fouled up had been in the bike for a while, a little bit of spooge but not too much, running at 33:1 castrol racing 2stroke and 98, wasnt to deep, maybe just past the foot pegs, i will clean the carb out tomorrow and see how it goes

Hi I would think clean carb, new fuel (if not new all ready) , clean airfilter and I would have thought 40:1 would be better for a 125
If that does nt work recheck compression , I dont think it would take to much to have it running mint now you have done piston / barrel .
Bring on the cambridge trail ride on staurday (hope the weather is ok )
