...........with my TTHP48", its got around 200 hours, The first problem I had was the engine, the govener would go up and down, So the dealer and I put new coils, fuel pump(& filter), spark plugs, air filter, and a new carb (I put on because they told me it need one, but thats another story) It solved the problem for a week, then did it again, and a freind helped me and said the bolt on the governer was loose, and we adjusted the carb, It fixed the problem and ran good for 3-4 week. Now the mower starts bogging down in some what thick grass, that it use to plow though with no problem, I even tryed taking the baffles out and side discharging, and it still bogged down, The blade speed will start to slow, and then the belt will slip and make noise, and the engine Rpms go down. And the engine is starting to do the governer thing again Im not sure if they go together are not? I plan on ordering new belts(just to have extra), Should I order a clucth? Are anything else I should order that could help my problem? I rather order extra parts and have them on hand than wait a week are more to get my mower fixed. I almost ready to order a engine! Thank you for any help!
