i posted in the ski doo section an no replys so far. so maybe some engine guy in this section can help me out a little... long story short got a 521 started missing last year found the suction line for the fuel pump very loose and barely hanging on, well needless to say that cylinder (magneto side) had no comp. started tearing it down and the top ring groove and ring are completely gone and imbeeded in the head and what not... just wondering if the fuel line is possibly the entire problem or am i looking for somthing else... if you read my thread in the ski doo section you may be able to get a little more info... i wanna bring this sled back to life because it is in good shape for an 87 but i dont wanna keep spending money.... i gotta line on two standard jugs n pistons plus a head for $300 plus i still need a gasket set.. so at this point im looking at about $350
