I posted this in the performance section under a reply but no answers so here it is.
Basically my HS50 is the 25mph verson but I can only get 20 out of it.
Carb looks nearly brand new, decarbonized the piston head & muff.
Three problems; 1 crank axel is bent so the drive pully wobbles, 2 paper gasket on read valve is deteriorated, 3 base gasket is missing.
Would this cause a 5mph loss or more? Im ordering parts from Mopedjunkyard as soon as I get paid on Fri. So well see…
Also Im having a problem with carbon buildup on the piston head, sparkplug, and Muff. Im running it 50/1 and putting a tad bit of marvel mystery oil as well. The build up in the muff is also oily. The build up happens pretty quickly. What could cause this?
Thanks for every ones help. :)
